Denial Of Service
Monthly
Unauthenticated database writes in CyberPanel versions before 2.4.4 allow remote attackers to abuse two AI Scanner worker endpoints (/api/ai-scanner/status-webhook and /api/ai-scanner/callback) that ship without authentication checks (CWE-306). Because no credentials are required (CVSS 4.0 PR:N/UI:N), any attacker who can reach the panel can flood the database, corrupt scan-history records, and pollute stored fields, degrading integrity and availability. Publicly available exploit code exists and the flaw was reported by VulnCheck, though EPSS remains low at 0.21% and it is not listed in CISA KEV.
Integer overflow in OP-TEE OS RSA signature encoding crashes the Trusted Execution Environment on platforms with RSA hardware acceleration. Affects versions 3.8.0 through 4.10 when attackers supply cryptographic operations with deliberately undersized RSA moduli, causing memset() to overwrite memory until the TEE crashes. This denial-of-service attack requires no authentication and can be triggered remotely (CVSS AV:N/PR:N), completely disabling the secure-world environment that protects cryptographic keys, biometric data, and DRM operations on affected Arm TrustZone systems. EPSS data not available; no active exploitation confirmed at time of analysis.
Unauthenticated remote attackers can crash Node.js applications using marked versions 18.0.0-18.0.1 by sending a specially crafted 3-byte sequence (tab, vertical tab, newline). The infinite recursion loop exhausts memory and triggers an out-of-memory crash, enabling complete denial of service against any exposed markdown parsing endpoint. Vendor-released patch fixes the vulnerability in version 18.0.2. No public exploit identified at time of analysis, though the attack input is trivially simple and reproducible. CVSS v4.0 8.7 reflects high availability impact with network reachability and no authentication barriers.
Unbounded memory allocation in Eclipse zserio serialization framework allows remote attackers to trigger system crashes via crafted payloads as small as 4-5 bytes, forcing allocations up to 16 GB and causing out-of-memory errors. Affects both C++ and Java runtimes used in Navigation Data Standard (NDS) implementations deployed across millions of vehicles from Toyota, BMW, Volkswagen, Mercedes-Benz, and 39 other automotive manufacturers. Vendor-released patch available in zserio v2.18.1, addressing unchecked length parameters in Array.h, BitStreamReader.h, and Java runtime equivalents. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation without authentication.
Pre-authentication NoSQL injection in Dgraph allows remote unauthenticated attackers to exfiltrate entire databases and modify schemas via crafted JSON mutation keys. The vulnerability exploits unsanitized language tag fields in the addQueryIfUnique function, enabling DQL query injection through specially crafted HTTP POST requests to port 8080. Attackers can extract all database contents including credentials, secrets, and AWS keys with two HTTP requests against default configurations where ACL is disabled. CVSS 9.1 (Critical) with network vector, no authentication required, and low attack complexity. No public exploit code confirmed outside the GitHub advisory, though a complete proof-of-concept with video demonstration exists in the advisory. EPSS data not available for this recent CVE.
Remote unauthenticated attackers can exfiltrate all data from Dgraph databases via DQL injection in the /mutate endpoint's cond parameter. Default configurations with ACL disabled allow single HTTP POST requests to bypass authentication and execute arbitrary read queries, returning complete database contents including credentials, PII, and secrets. The vulnerability exploits unsanitized string concatenation in buildUpsertQuery() where user-supplied cond values are written directly into DQL queries without escaping or validation. Proof-of-concept demonstrates extraction of AWS credentials, GCP service account keys, and user secrets in a single request. No public exploitation confirmed at time of analysis, but POC code publicly available via GitHub advisory. EPSS data not available; CVSS 9.1 indicates critical severity with network vector and no authentication required.
Use-after-free in Linux kernel batman-adv (B.A.T.M.A.N. Advanced mesh networking) allows remote network attackers to trigger memory corruption and potentially execute arbitrary code. The batadv_bla_add_claim() function can prematurely drop a gateway reference while readers still access the pointer, causing netlink dump and claim-check paths to dereference freed memory. Despite CVSS 9.8 critical rating, exploitation probability is low (EPSS 2%, 7th percentile), no active exploitation confirmed, and patches available across kernel stable branches 6.1.169, 6.6.135, 6.12.82, 6.18.23, 6.19.13, and mainline 7.0.
Race condition in Linux kernel memory management allows local attackers with low privileges to corrupt kernel page state, potentially achieving high-impact denial of service, data corruption, or privilege escalation. The vulnerability affects kernel versions 6.6.x through 7.0-rc3, with patches confirmed released for stable branches 6.6.135, 6.12.82, 6.18.23, 6.19.13, and mainline 7.0. EPSS exploitation probability is low (0.02%, 5th percentile), and no public exploit code or active exploitation has been identified at time of analysis. The CVSS vector (AV:L/AC:L/PR:L/UI:N) indicates local access with low attack complexity, while the specific race condition requires precise timing between file mapping and inode size modification operations.
Null pointer dereference in Linux kernel rxrpc subsystem allows remote network attackers to crash the system by sending malformed packets to a client-side connection after a call has been torn down. The flaw affects Linux kernel versions 6.2 onward where the rxrpc client code unconditionally releases a call reference that was never acquired, converting a protocol error into a kernel panic. Vendor patches are available across stable branches (6.6.135, 6.12.82, 6.18.23, 6.19.13, 7.0). EPSS exploitation probability is low (0.02%, 5th percentile) and no public exploit has been identified at time of analysis.
Kernel panic in Linux arm64 memory management causes system crash when handling invalid large leaf page table mappings during DMA bounce buffer operations. ARM64 systems running Linux 7.0-rc4 and earlier (specifically kernels with commit a166563e7ec37 that introduced large block mapping support) crash with translation faults when components like SWIOTLB, secretmem, kfence, or realm DMA attempt to invalidate large leaf mappings. Exploitation requires no special privileges as this is triggered by normal kernel operations during boot or DMA activity. Vendor patches available across stable branches (6.18.24, 6.19.14, 7.0.1). EPSS score is 1st percentile (0.01%) indicating extremely low observed exploitation probability, consistent with this being an availability issue requiring specific ARM64 hardware configurations rather than a remotely exploitable vulnerability.
Use-after-free in Linux kernel blk-cgroup subsystem allows local authenticated users to potentially execute arbitrary code, escalate privileges, or crash the system. The vulnerability occurs in cgwb_release_workfn() when releasing cgroup writeback structures, where a CSS reference is dropped before subsequent dereference, creating a race condition. Meta reports sporadic crashes in production across multiple kernel versions. Patches available for stable branches 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% suggests low widespread exploitation probability, and no active exploitation or public POC identified at time of analysis.
Local privilege escalation and denial of service in the Linux kernel's em28xx USB media driver arises from a use-after-free (CWE-416) in em28xx_v4l2_open(), which reads dev->v4l2 without holding dev->lock. A local attacker who can open the V4L2 device node during a race with the driver's init error path or teardown can trigger a use-after-free on the embedded video_device (via v4l2_fh_init accessing vdev->ctrl_handler) or a NULL dereference in em28xx_resolution_set(). No public exploit identified at time of analysis, and EPSS is very low (0.02%), consistent with a hard-to-win kernel race requiring physical/local USB device presence.
Local privilege escalation and denial of service in the Linux kernel's bcache subsystem stems from a use-after-free of the cached_dev.sb_bio structure; if a cached backing device is stopped while a superblock write is in flight, the freed bio is dereferenced at I/O completion (endio), corrupting kernel memory. Affected systems are those running bcache-backed block devices (observed crashing via librbd/libceph rbd workloads), where a local user with the ability to trigger device teardown during superblock activity can crash the host or potentially corrupt kernel memory. This carries no public exploit identified at time of analysis and an EPSS of just 0.02%, consistent with a hard-to-time race rather than a readily weaponized flaw.
Denial of service via CPU soft lockup in Linux kernel's wlcore Wi-Fi driver (versions 5.10 through 7.0) occurs when memory allocation fails during wireless frame transmission. Incorrect error code return (-EAGAIN instead of -ENOMEM) triggers infinite retry loop while holding critical mutex, causing system unresponsiveness. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.167, 6.6.130, 6.12.78, 6.18.20, 6.19.10, 7.0). CVSS 7.5 (High) reflects network attack vector with no authentication required, though EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV); no public exploit identified at time of analysis.
Use-after-free race condition in Linux kernel Wi-Fi cfg80211 subsystem allows local authenticated users to trigger kernel crashes or potentially execute code. When a nl80211 socket closes while a peer measurement (PMSR) request is active, concurrent interface teardown can leave a scheduled work item (pmsr_free_wk) that later invokes the driver's abort callback on already-freed interface structures. EPSS score of 0.02% (7th percentile) indicates very low probability of exploitation in the wild. Patches available across all supported kernel branches since commit 9bb7e0f24e7e (introduced in Linux 5.0), with fixes released in stable versions 6.1.167, 6.6.130, 6.12.78, 6.18.20, and 6.19.10.
Denial of service in Grafana Tempo allows unauthenticated remote attackers to exhaust server memory by sending trace queries with excessively large result limits. The vulnerability causes unbounded memory allocation during query processing, degrading or halting service availability depending on deployment resources. EPSS data not available; no CISA KEV listing or public exploit identified at time of analysis. Mitigation available through configuration change rather than software patch.
Remote unauthenticated attackers can trigger denial of service in Delta Electronics AS320T industrial automation devices by invoking an undocumented subfunction. The vulnerability allows network-accessible exploitation without credentials against default configurations, potentially disrupting critical industrial control operations. Delta Electronics confirmed the flaw in PCSA-2026-00006, grouped with three other CVEs affecting the same product line.
Denial of service in basic-ftp for Node.js allows remote malicious FTP servers to crash client applications via unbounded memory consumption during directory listing operations. Attackers controlling or compromising an FTP server can send infinite or extremely large listing responses to Client.list() calls, exhausting client memory until process termination. Unauthenticated network attack with low complexity (CVSS:3.1 AV:N/AC:L/PR:N). No public exploit identified at time of analysis, though attack concept is straightforward for anyone operating a malicious FTP server.
A type assertion bug in Kyverno's forEach mutation handler crashes the cluster-wide background controller into CrashLoopBackOff and blocks admission controller operations, causing denial of service for policy-matched resources. Any authenticated user with Policy or ClusterPolicy creation permissions can trigger the crash by creating a malformed policy. The vulnerability affects Kyverno versions prior to 1.17.2 and 1.16.4, is limited to the legacy policy engine (CEL-based policies unaffected), and persists until the malicious policy is deleted. Vendor-released patches available with confirmed fix commits on GitHub.
Resource exhaustion in Open Source Social Network (OSSN) versions prior to 9.0 allows remote unauthenticated attackers to trigger Denial of Service by uploading specially crafted images with extreme pixel dimensions (e.g., 10000×10000). While the compressed file size appears small, server-side decompression and resizing allocates excessive memory and CPU, crashing or degrading service. EPSS exploitation probability data not available, but the attack vector is straightforward (AV:N/AC:L/PR:N) with publicly documented technical details and fix commit available on GitHub. CVSS 8.2 reflects the easy remote exploitation path despite limited confidentiality impact.
Denial of service in libxml2 allows a remote attacker to crash any application that uses the library to XSD-validate an attacker-supplied XML document containing an internal entity reference. The flaw is a CWE-843 type confusion triggered during schema validation, affecting a wide range of Red Hat products that ship libxml2. No public exploit identified at time of analysis, and EPSS is very low (0.01%, 3rd percentile), consistent with SSVC exploitation status of 'none'.
Denial of service in OpenClaw before 2026.3.31 lets remote attackers exhaust image-gateway memory by submitting a decompression bomb - a tiny compressed image that decodes to an enormous pixel count. The pixel-limit guard fails open on the sips backend, so oversized images are decoded before any size check runs. EPSS is very low (0.03%, 9th percentile) and there is no public exploit identified at time of analysis; a vendor patch (2026.3.31) is available.
Denial of service in SWUpdate (versions through 2025.12) allows unauthenticated remote attackers to crash the update service by sending a crafted HTTP POST to the /upload endpoint with a malformed multipart boundary and controlled TCP stream timing. An integer underflow in the bundled Mongoose multipart parser produces an out-of-bounds heap read that corrupts data written to a local IPC socket. No public exploit identified at time of analysis; EPSS is very low (0.03%) and CISA SSVC rates exploitation as none, but a vendor patch commit is available.
Lua code injection in Contour (Kubernetes ingress controller for Envoy) from v1.19.0 through the fixes in v1.31.6/v1.32.5/v1.33.4 lets a low-privileged tenant achieve arbitrary code execution inside the shared Envoy proxy. A user with RBAC rights to create or modify HTTPProxy resources injects Lua via the cookie-rewrite pathRewrite.value field; although the code only runs on the attacker's own route, it executes in shared infrastructure and can steal Envoy's xDS credentials (exposing other tenants' TLS keys) or cause denial of service for co-tenants. No public exploit identified at time of analysis, and EPSS is low (0.07%, 22nd percentile), consistent with the requirement for pre-existing cluster RBAC access.
Denial of service in the Argo Workflows controller (versions 3.6.5 through 4.0.4, plus the 3.7.0-rc1 through 3.7.12 pre-releases) lets any user able to submit a workflow crash-loop the entire controller by attaching a malformed workflows.argoproj.io/pod-gc-strategy pod annotation that contains no '/' separator, triggering an out-of-range index panic in an informer goroutine that sits outside the controller's recover() scope. Because the poisoned pod persists across restarts, the controller enters CrashLoopBackOff and halts all workflow processing cluster-wide until the pod is manually deleted. A working proof-of-concept manifest is published in the GHSA advisory (SSVC exploitation status: poc), but there is no evidence of active exploitation and EPSS is very low at 0.04%.
Sandbox escape in Google Chrome's DevTools component (versions prior to 147.0.7727.117) lets an attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page. Rated High by Chromium and CVSS 9.6, this is a use-after-free (CWE-416) that serves as the second link in a multi-stage exploit chain rather than a standalone remote code execution. No public exploit identified at time of analysis, EPSS is very low (0.03%), and CISA SSVC records no observed exploitation, so it is a patch-and-move-on desktop browser fix rather than an emergency.
Out-of-bounds memory read in the X.Org X server's XKB key types request handling allows a local, authenticated client to disclose adjacent server memory or crash the server (DoS), with higher-impact outcomes possible in certain configurations. The flaw affects the X server component shipped across Red Hat Enterprise Linux 6 through 10 and corresponding SUSE releases, and stems from missing bounds validation on an XKB request. There is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and CISA/SSVC records no known exploitation.
Local privilege-relevant memory corruption in the X.Org X server arises from a use-after-free in the XSYNC fence-triggering path (miSyncTriggerFence()), letting any client with a connection to the display crash the server or corrupt heap memory without user interaction. Rated CVSS 7.8 with total technical impact per CISA SSVC, it currently shows no public exploit identified at time of analysis, no CISA KEV listing, and a very low EPSS of 0.01% (3rd percentile). Because the X server frequently runs with elevated privileges, successful memory corruption could escalate beyond denial of service.
Memory-disclosure and denial-of-service in the X.Org X server arises from an integer underflow (CWE-191) in the XKB compatibility map handling, which lets a client with local or remote X11 access trigger an out-of-bounds buffer read. Any attacker able to open a connection to the display server can crash it or read adjacent server memory, with Red Hat and SUSE rating the technical impact as total; no public exploit identified at time of analysis and EPSS is negligible (0.01%, 2nd percentile). This was reported by Red Hat and affects the X server shipped across Red Hat Enterprise Linux 6 through 10.
Unauthenticated remote file read/write and NTLM coercion in Kofax Capture (rebranded Tungsten Capture) 6.0.0.0 stems from the Ascent Capture Service exposing a deprecated .NET Remoting HTTP channel on TCP/2424 with a default, publicly known endpoint identifier and no authentication. A remote attacker can abuse .NET Remoting object unmarshalling to instantiate a server-side System.Net.WebClient, allowing arbitrary file read/write and coerced NTLMv2 authentication that can cascade into credential theft, denial of service, remote code execution, or lateral movement depending on the service account's privileges. Publicly available exploit code exists (VulnCheck/gist PoC); it is not listed in CISA KEV, and EPSS is low at 0.16% (37th percentile).
Remote denial of service via regular expression attack in GROWI allows unauthenticated network attackers to exhaust server resources by submitting maliciously crafted input strings that trigger catastrophic backtracking in regex processing (CWE-1333). GROWI, Inc.'s collaboration platform is vulnerable to ReDoS with a CVSS 4.0 base score of 8.7 (High), reflecting high availability impact through network-accessible, low-complexity exploitation requiring no privileges or user interaction. No CISA KEV listing or public exploit code identified at time of analysis, though vendor advisory confirms the vulnerability and provides remediation guidance.
HTTP response splitting and denial-of-service in i18next-http-middleware < 3.9.3 allows remote unauthenticated attackers to inject arbitrary HTTP headers or crash Node.js processes via CRLF sequences in the lng parameter. On Node.js < 14.6.0, attackers achieve response splitting enabling session fixation, cache poisoning, and reflected XSS. On Node.js ≥ 14.6.0, malformed headers trigger unhandled ERR_INVALID_CHAR exceptions, returning 500 errors to all concurrent users sharing the affected process. Vendor-released patch available in version 3.9.3. No public exploit identified at time of analysis, though exploitation is trivial given the attack vector (simple query parameter manipulation).
Denial of service in @xmldom/xmldom Node.js XML library allows remote attackers to crash applications via deeply nested XML documents. Seven DOM traversal methods (normalize, serializeToString, getElementsByTagName, cloneNode, importNode, textContent getter, isEqualNode) implement unbounded recursion consuming call stack frames until RangeError exception terminates the process. Exploitation requires no authentication - attackers send a single valid XML payload nested ~5,000-10,000 levels deep to trigger stack exhaustion in any subsequent DOM operation. Browser implementations of identical DOM methods use iterative C++ code and are unaffected. CVSS 8.7 High severity reflects network attack vector with no complexity barriers. Vendor-released patches (0.8.13, 0.9.10) replace all recursive traversals with iterative 'walkDOM' utility consuming heap instead of stack. Legacy unscoped 'xmldom' package (≤0.6.0) remains unfixed.
Remote unauthenticated denial of service crashes Nimiq blockchain nodes by exploiting a protocol state machine flaw. Attackers can force panic conditions in the libp2p discovery handler by opening duplicate protocol substreams, immediately taking peer-to-peer networking offline until manual restart. Vendor-released patch available in version 1.3.0 with no workarounds for unpatched systems, creating urgent upgrade requirement for blockchain node operators.
Remote denial of service in dnsdist allows unauthenticated attackers to crash the DNS load balancer by sending specially crafted DNSCrypt queries that trigger a divide-by-zero error. The vulnerability requires no authentication, low attack complexity, and directly impacts service availability for all DNS traffic routed through affected dnsdist instances. Organizations using DNSCrypt protocol support in dnsdist face immediate risk of service disruption from remote attackers.
Use-after-free in Linux kernel CXL (Compute Express Link) subsystem allows local authenticated attackers to corrupt memory and potentially execute arbitrary code or cause kernel panics. The flaw occurs in cxl_detach_ep() during device removal when parent port references are freed prematurely, before child operations complete. Affects Linux kernel 6.3 through 7.0-rc5; patched in versions 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% indicates low exploitation probability. No active exploitation or public exploit code identified at time of analysis.
Double-free vulnerability in Linux kernel SMC (Shared Memory Communications) splice handling allows local authenticated attackers to trigger use-after-free conditions and kernel panic. The flaw occurs when tee(2) duplicates an SMC pipe buffer: both the original and cloned pipe_buffer share the same smc_spd_priv pointer, causing smc_rx_pipe_buf_release() to free the same memory twice on pipe cleanup. This escalates from KASAN-detected slab-use-after-free to NULL pointer dereference in smc_rx_update_consumer(), resulting in denial of service via kernel crash. Vendor patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS exploitation probability is low (0.02%, 7th percentile) with no public exploit or CISA KEV listing at time of analysis.
Type confusion in Linux kernel team driver allows local authenticated users to trigger memory corruption and potential privilege escalation. The team_setup_by_port() function incorrectly copies header_ops from non-Ethernet lower devices (such as GRE interfaces) without proper context validation, causing callbacks like dev_hard_header() to interpret netdev_priv() as the wrong structure type when processing stacked network topologies (e.g., gre → bond → team). While CVSS rates this 7.8 (High), EPSS probability is very low at 0.02% (5th percentile), and no active exploitation or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0).
Use-after-free in Linux kernel SPI subsystem (fsl_lpspi driver) causes NULL pointer dereference when DMA channels are torn down while SPI transfers are active. Local attackers with low privileges can trigger denial of service or potentially execute arbitrary code on affected systems running Linux kernel versions from 4.10 through 7.0-rc2, particularly impacting embedded and IoT devices using Freescale LPSPI controllers. EPSS score of 0.02% indicates very low observed exploitation probability, and no public exploit code or active exploitation has been identified at time of analysis. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).
Memory exhaustion and kernel crash in Linux kernel's ksmbd SMB server allows remote unauthenticated denial of service via crafted lock requests. The smb2_lock() function contains three critical error-handling defects: memory leaks when vfs_lock_file() returns unexpected errors, stale error propagation in UNLOCK operations, and NULL pointer dereference during rollback when smb_flock_init() allocation fails. CVSS vector indicates network-accessible, low-complexity exploitation requiring no authentication. EPSS score of 0.02% (7th percentile) suggests minimal observed scanning activity, and no KEV listing confirms no widespread exploitation detected. However, the network attack vector (AV:N) and high availability impact (A:H) make this a realistic DoS risk for systems running ksmbd. Vendor patches available across stable kernel series 5.15-6.19.
Use-after-free in Linux kernel's XFS filesystem allows local authenticated users to achieve arbitrary code execution, privilege escalation, or information disclosure. The vulnerability occurs in the XFS Active Item List (AIL) push mechanism where log items can be freed by background reclaim processes while still being dereferenced by tracepoints. Vendor patches are available for kernel versions 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (7th percentile) indicates very low observed exploitation probability in the wild, and no public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.
Race condition in Linux kernel ext4 filesystem allows denial of service through kernel panic when fast commit feature processes incompletely initialized journal inodes. Affects Linux kernel versions from 3.11 through multiple stable branches (5.10.x, 5.15.x, 6.1.x, 6.6.x, 6.12.x, 6.18.x, 6.19.x) prior to patched versions released in early 2025. Vendor patches available across all affected stable branches. EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. Not listed in CISA KEV, and no public exploit code identified at time of analysis. CVSS 8.8 reflects authenticated network attack vector, though real-world risk limited to systems where attackers have filesystem write access and ext4 fast commit is enabled.
Denial of service in Linux kernel ext4 filesystem allows remote attackers to trigger infinite loops and system hangs (143+ second inode lock blocking) via crafted mkdir/mknod operations. The vulnerability stems from incomplete cleanup when extent insertion fails - ext4_ext_map_blocks() reclaims physical blocks without deleting stale extent tree entries, causing reuse of blocks already allocated to xattrs. This triggers infinite loops in ext4_xattr_block_set() that hold inode locks indefinitely. With CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) but EPSS only 0.02% (percentile 7), the network attack vector rating appears inconsistent with typical local filesystem exploitation. Patches available across stable kernel branches 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. No active exploitation confirmed (not in CISA KEV), but tagged for denial-of-service impact.
Use-after-free and descriptor management error in Linux kernel's Intel IDXD DMA engine driver allows NULL pointer dereferences, double completion, or descriptor leaks. The llist_abort_desc() function completes the wrong descriptor object due to a loop cursor bug introduced in commit aa8d18becc0c. Patches released for kernel 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS exploitation probability is very low (0.02%, 5th percentile), and no active exploitation or public exploit code identified. Despite CVSS 9.8 critical rating with network vector, the actual attack surface requires local access to DMA engine subsystems, making the CVSS vector likely inaccurate or context-dependent.
Heap buffer overflow in GNU Binutils XCOFF linker allows arbitrary code execution when a local user processes a malicious object file. Red Hat Enterprise Linux versions 6 through 10 are confirmed affected via CPE data. CVSS 7.8 reflects local attack vector requiring user interaction (opening/linking the crafted file). No active exploitation confirmed (not in CISA KEV), and no public proof-of-concept identified at time of analysis. Real-world risk depends heavily on whether development workflows involve linking untrusted XCOFF files, which is uncommon outside AIX/PowerPC cross-compilation scenarios.
Uncontrolled resource consumption in Progress Telerik UI for AJAX RadAsyncUpload component allows remote unauthenticated attackers to exhaust disk space by uploading files exceeding configured size limits through chunked upload bypass. The vulnerability arises from missing cumulative size validation during chunk reassembly, enabling attackers to circumvent intended upload restrictions. No authentication required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N), making this exploitable against any internet-facing application using affected versions. Patch available in version 2026.1.421. No CISA KEV listing or public exploit code identified at time of analysis, but low attack complexity and no authentication barrier indicate straightforward exploitation potential.
Concurrent DAAP login requests crash OwnTone Server 28.4-29.0 via race condition in session list handling, causing remote denial of service without authentication. Attack complexity is high (CVSS AC:H) but requires no privileges, enabling unauthenticated attackers to flood the /login endpoint and trigger crashes through unsynchronized global state access. Vendor patch available via GitHub commit dca94641; no active exploitation confirmed at time of analysis.
Remote unauthenticated denial of service affects facil.io (all versions prior to commit 5128747) and iodine (all versions before 0.7.59) through malformed JSON input triggering infinite CPU loop. Attackers can send crafted JSON payloads as small as two bytes ('[i') to the `fio_json_parse` function, causing the process to consume 100% of a CPU core indefinitely without crashing or returning an error. This vulnerability allows trivial resource exhaustion against any web service using these frameworks to parse untrusted JSON. EPSS data not available; no confirmed active exploitation (CISA KEV absent), but the attack requires only network access with no authentication and minimal complexity (CVSS AV:N/AC:L/PR:N), making exploitation straightforward once discovered.
Unauthenticated remote attackers can crash free5GC Policy Control Function (PCF) versions before 1.4.3 via repeated HTTP requests to the OAM endpoint over the Service-Based Interface. Each request leaks memory by registering duplicate CORS middleware in the Gin router handler chain, causing progressive memory exhaustion that prevents all User Equipment from establishing 5G sessions. Patched in version 1.4.3 via commit 599803b. EPSS data unavailable; not listed in CISA KEV. CVSS 7.5 High severity reflects network-accessible unauthenticated attack with high availability impact.
Denial-of-service in Oracle Identity Manager Connector (Core component) version 12.2.1.4.0 lets a remote, unauthenticated attacker send network traffic over TCP to hang or repeatedly crash the service, producing a complete availability outage (CVSS 3.1 7.5). Oracle disclosed this in the April 2026 Critical Patch Update; there is no public exploit identified at time of analysis, and EPSS is very low (0.04%). Confidentiality and integrity are unaffected - the impact is purely availability (CWE-400, resource exhaustion).
Denial of service in the Networking component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition allows an unauthenticated, network-based attacker to cause a hang or repeatable crash (complete availability loss) of the affected runtime. The flaw is described by Oracle as easily exploitable via multiple protocols against any application that feeds attacker-controlled data to the vulnerable networking APIs (e.g., an exposed web service). There is no public exploit identified at time of analysis; EPSS is very low (0.04%, 12th percentile) and CISA SSVC lists exploitation status as none, so this is a patch-in-cycle availability issue rather than an active threat.
Remote denial of service in Coturn TURN/STUN server allows unauthenticated attackers to crash ARM64 deployments with a single malformed UDP packet. The vulnerability triggers a fatal SIGBUS signal via misaligned memory access during STUN attribute parsing, requiring no authentication or special configuration. All ARM64 installations of Coturn prior to 4.10.0 are vulnerable to instant process termination. EPSS exploitation probability is not yet available as this is a newly disclosed CVE, but the attack complexity is low (AC:L) and requires no privileges (PR:N), making exploitation trivial once awareness spreads in attacker communities.
Out-of-bounds read in NVIDIA CUDA-Q endpoint allows remote unauthenticated attackers to crash services and disclose sensitive memory contents via malformed network requests. The vulnerability affects an exposed network endpoint with no authentication barrier (CVSS AV:N/AC:L/PR:N/UI:N), enabling trivial exploitation against internet-facing deployments. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis, suggesting exploitation remains theoretical or limited to targeted scenarios.
Unauthenticated remote attackers can access administrative diagnostic endpoints in FreeScout versions prior to 1.8.213, exploiting a predictable MD5 hash derived from the exposed APP_KEY. Attackers can harvest sensitive server information (full path disclosure, process IDs) and trigger resource exhaustion denial-of-service by repeatedly invoking unprotected background tasks. The vulnerability has publicly available exploit code (CVSS E:P), making it immediately actionable for attackers. EPSS data not provided, but the combination of network exposure (AV:N), no authentication required (PR:N), and confirmed POC significantly elevates real-world risk for internet-facing FreeScout installations.
Denial-of-service in Firefox versions prior to 150 allows remote attackers to crash the browser via malformed audio/video content during playback. The vulnerability requires no authentication and minimal attack complexity (CVSS 7.5, AV:N/AC:L/PR:N/UI:N), enabling attackers to render the browser unresponsive or terminated through crafted media files. Mozilla has released Firefox 150 to address this issue. EPSS data not available; no evidence of active exploitation (not in CISA KEV), though SSVC assessment notes the vulnerability is not currently being exploited and is classified as non-automatable with partial technical impact.
Denial-of-service in Firefox's Audio/Video playback component allows remote attackers to crash the browser via network-based exploitation requiring no authentication or user interaction. Mozilla patched the vulnerability in Firefox 150. CVSS 7.5 (High) reflects high availability impact, but SSVC assessment marks it as partial technical impact with no confirmed exploitation, indicating lower real-world priority than critical RCE vulnerabilities. No public exploit code or CISA KEV listing identified.
Signal K Server versions before 2.25.0 allow remote unauthenticated attackers to crash the server via Regular Expression Denial of Service (ReDoS) in WebSocket subscription handling. By injecting unescaped regex metacharacters into the context parameter, attackers trigger catastrophic backtracking that consumes 100% CPU and renders the server completely unresponsive to all API and socket requests. This creates a complete denial of service for marine navigation systems relying on Signal K Server as their central data hub. While EPSS score is low (0.04%, 13th percentile), the trivial exploitation complexity (AV:N/AC:L/PR:N/UI:N) and complete availability impact make this a priority for boat operators running vulnerable versions. No public exploit identified at time of analysis, but the GitHub security advisory provides clear technical details. Vendor-released patch available in version 2.25.0.
Out-of-bounds read in GNU C Library (glibc) versions 2.1.1 through 2.43 during wide character pushback operations can cause application crashes and potential information disclosure. The ungetwc() function incorrectly operates on the regular character buffer instead of the wide-stream buffer due to an implementation bug in _IO_wdefault_pbackfail, leading to reads before allocated memory regions. While CVSS rates this 7.5 High with network vector, EPSS exploitation probability is extremely low (0.02%, 5th percentile), reflecting the highly specialized conditions required: applications must use ungetwc() with character encodings having single-byte/multi-byte overlaps (not standard Unicode sets). No active exploitation confirmed (not in CISA KEV), no public exploit code identified at time of analysis.
Path traversal in Everest Forms (WordPress plugin) allows unauthenticated attackers to read and delete arbitrary files on the server through malicious form submissions containing crafted old_files parameters. Vulnerable versions ≤3.4.4 use regex-based path resolution without canonicalization, enabling attackers to traverse directories, exfiltrate wp-config.php via email attachments (exposing database credentials and authentication salts), and trigger automatic deletion of targeted files post-email. CVSS 8.1 (AV:N/AC:H) reflects the remote vector with high attack complexity. EPSS and KEV status not provided; proof-of-concept details available in Wordfence advisory and plugin source code references.
Control-flow disruption in XiangShan open-source RISC-V processor allows local authenticated attackers to trigger denial of service through malformed CSR operations that fail to properly invoke trap handlers. Affected commits from November 2024 contain improper exception handling in the NewCSR subsystem that can leave the processor core in a hung state when targeting non-existent CSR addresses. GitHub issue #3959 and pull request #3966 document the flaw and proposed fix. EPSS score of 0.02% (5th percentile) indicates very low predicted exploitation probability. No public exploit code identified and not listed in CISA KEV, suggesting primarily theoretical risk limited to specialized RISC-V development environments.
Denial of service and incorrect virtualization-configuration enforcement affect NEMU, the OpenXiangShan RISC-V full-system emulator, because its Hypervisor CSR logic derives henvcfg[7:4] (the CBIE/CBCFE/CBZE cache-block-management fields) from menvcfg[7:4] via an erroneous mask on read. As a result, machine-mode code that writes menvcfg implicitly mutates the hypervisor environment configuration, so guest code running virtualized (V=1) can hit unexpected traps or a denial-of-service when executing cache-block-operation (cbo.*) instructions. No public exploit is identified at time of analysis; EPSS is 0.01% and CISA SSVC lists exploitation as 'none', which conflicts sharply with the 9.8 NVD base score.
Availability-impacting instruction-decoding flaw in OpenXiangShan NEMU (a RISC-V emulator/reference model) before v2025.12.r2 lets crafted RISC-V binaries slip malformed OP-V encodings past the RVV decoder. Because the decoder fails to validate the funct3 field, invalid vector instructions are misinterpreted and executed as vsetvli/vsetivli/vsetvl configuration instructions instead of raising an illegal-instruction exception, causing incorrect trap behavior, architectural-state divergence, and denial of service. There is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and CISA SSVC records exploitation status as none.
OpenXiangShan NEMU emulator's RISC-V Hypervisor extension implementation allows VS-mode guest writes to the sie (supervisor interrupt-enable) CSR to corrupt machine-level mie state, breaking privilege isolation between virtualization layers. Fixed in commit 55295c4 per GitHub PR #938. Despite CVSS 9.8 Critical rating with network attack vector (AV:N), the EPSS score of 0.03% (9th percentile) indicates extremely low observed exploitation probability, and the vulnerability specifically affects RISC-V emulator environments rather than typical network-accessible services. No CISA KEV listing or public exploit identified at time of analysis, suggesting this is a theoretical high-severity issue in specialized research/development contexts rather than an imminent widespread threat.
Uncontrolled memory consumption in monetr 1.12.3 and earlier allows remote unauthenticated attackers to trigger denial of service by sending oversized payloads to the public Stripe webhook endpoint. The vulnerability affects deployments with Stripe webhooks enabled and lacks upstream body-size enforcement. Version 1.12.4 provides a fix. EPSS and KEV data not available; no public exploit confirmed at time of analysis, though the attack method is straightforward (8.2 CVSS reflecting high availability impact with low complexity).
Integer underflow in miniupnpd's SOAPAction header parser triggers out-of-bounds memory reads, enabling adjacent network attackers to crash UPnP-enabled routers or leak sensitive memory contents without authentication. Affects miniupnpd versions prior to 2.3.10. Vendor patch available via commit a0ee71e9fa66. CVSS 7.1 with adjacent network vector (AV:A) indicates attackers must be on the same local network segment as the vulnerable device. No active exploitation confirmed in CISA KEV at time of analysis.
NoSQL injection in FastGPT <4.14.9.5 password authentication allows unauthenticated remote attackers to bypass login controls and access any account, including root administrator, by submitting MongoDB query operators instead of plaintext passwords. The vulnerability stems from missing runtime validation on password fields in the login endpoint. Exploitation requires no special conditions beyond network access to the login endpoint. CVSS 9.8 (Critical) with EPSS data unavailable; no CISA KEV listing or public POC identified at time of analysis, though GitHub security advisory provides technical details that could enable exploit development.
Out-of-bounds read in xrdp RDP server versions ≤0.10.5 allows remote unauthenticated attackers to crash the service or disclose process memory by sending a malformed Confirm Active PDU during RDP capability negotiation. Attack complexity is low but requires user interaction. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis. Vendor-released patch available in version 0.10.6 per GitHub security advisory GHSA-rvh9-9wm3-28c7.
Heap-based buffer overflow in xrdp's NeutrinoRDP module (versions ≤0.10.5) enables malicious downstream RDP servers or MitM attackers to achieve remote code execution or denial of service when proxying RDP sessions. Exploitation requires the victim xrdp server to have the non-default NeutrinoRDP module compiled and enabled (--enable-neutrinordp), and a user must initiate an RDP session through the affected proxy to a malicious server. EPSS data unavailable; no CISA KEV listing indicates targeted rather than widespread exploitation. Fixed in version 0.10.6.
Firebird database server crashes via crafted slice packet exploiting zero-length SDL descriptor validation flaw. Remote unauthenticated attackers can trigger division-by-zero errors in the sdl_desc() function to cause denial of service against Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation with no authentication required. EPSS data not available; no public exploit identified at time of analysis, though technical details in GitHub advisory may facilitate reproduction.
Remote denial-of-service in Firebird Database Server versions prior to 5.0.4, 4.0.7, and 3.0.14 allows unauthenticated network attackers to crash the server via crafted XDR-encoded op_response packets. The xdr_status_vector() function fails to handle isc_arg_cstring status vector types during packet decoding, triggering immediate server termination. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) and CWE-228 (Improper Handling of Syntactically Invalid Structure), this represents a high-severity availability risk for internet-exposed Firebird instances. No active exploitation confirmed, but exploit development is trivial given the low attack complexity.
Null pointer dereference in Firebird SQL server causes remote denial-of-service when unauthenticated attackers send malformed op_crypt_key_callback packets. Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14 are affected. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms trivial remote exploitation requiring no authentication or user interaction, allowing attackers who know only the server's IP and port to crash database services. The integrity impact rating (I:L) suggests potential for limited data corruption alongside the high availability impact. Vendor-released patches are available in versions 5.0.4, 4.0.7, and 3.0.14. No public exploit code or CISA KEV listing identified at time of analysis, though the low attack complexity makes weaponization straightforward.
Remote unauthenticated denial of service in Firebird SQL database server versions prior to 6.0.0/5.0.4/4.0.7/3.0.14 allows attackers to crash the database by sending a malformed op_slice network packet that triggers a null pointer dereference in the SDL_info() function. Attack requires only network access to the database port with no authentication (CVSS AV:N/AC:L/PR:N). No public exploit code identified at time of analysis, and EPSS data not available for this recent CVE. Fixed versions released by vendor across all maintained branches.
Out-of-bounds write in dnsmasq's DHCP split-relay handler allows remote unauthenticated denial of service via crafted BOOTREPLY packets. Affects Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4 when dnsmasq runs with the --dhcp-split-relay option enabled. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial network exploitation, but real-world risk is mitigated by the non-default configuration requirement. No public exploit or active exploitation (CISA KEV) confirmed at time of analysis, though CWE-787 (out-of-bounds write) primitives are well-understood by attackers.
HashiCorp Vault unauthenticated denial-of-service vulnerability allows remote attackers to block critical administrative operations by monopolizing the single operation slot for root token generation and rekey workflows. Affects all Vault Community and Enterprise versions prior to 2.0.0. No active exploitation confirmed (EPSS 3rd percentile), but attack is trivially automatable per CISA SSVC framework. HashiCorp released patches in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0.
Unauthenticated information disclosure (IDOR) in the My Calendar WordPress plugin (versions ≤ 3.7.6) lets remote attackers read calendar events-including private and hidden ones-from any sub-site on a WordPress Multisite network by injecting an arbitrary site ID into the unauthenticated mcjs_action AJAX endpoint. On Single Site installations the same request triggers an uncaught fatal error, giving an unauthenticated denial-of-service vector. Publicly available exploit code exists, though EPSS remains very low (0.01%) and the flaw is not in CISA KEV. Fixed in version 3.7.7.
Unauthenticated remote denial-of-service in ChilliCream's Hot Chocolate GraphQL server for .NET (HotChocolate.Language package) lets any client crash the entire worker process by sending a small, deeply nested GraphQL document. Because the recursive-descent Utf8GraphQLParser has no depth limit, ~40 KB of nested selection sets, object/list values, or list types triggers an uncatchable StackOverflowException that terminates the process, dropping all in-flight HTTP requests, IHostedService background tasks, and WebSocket subscriptions on that worker. No public exploit identified at time of analysis and EPSS is low (0.09%), but the attack is trivial (AC:L, PR:N) and CISA SSVC flags it as automatable, so it is a practical availability threat to internet-facing GraphQL endpoints.
Unauthenticated denial of service in zrok's OAuth-protected proxy shares (openziti/zrok <= 1.1.11 and v2 < 2.0.1) lets a remote attacker crash the proxy process with a single crafted Cookie header. The GetSessionCookie routine reads an attacker-controlled cookie-stripe count and performs make([]string, count) with no upper bound before any authentication, driving gigabyte-scale heap allocations that cause OOM termination or goroutine panics across every share the proxy serves. There is no public exploit identified at time of analysis, and EPSS is low (0.06%), but exploitation is trivially automatable per CISA SSVC.
Denial of service in mcp-framework (npm) versions <= 0.2.21 lets a remote unauthenticated attacker crash any server using the HttpStreamTransport by sending a single oversized HTTP POST to /mcp, exhausting memory. The readRequestBody() function concatenates request-body chunks into a string with no cap, and although a 4MB maxMessageSize config value exists it is never enforced. Publicly available exploit code exists (SSVC 'poc'), a vendor patch shipped in 0.2.22, and EPSS is low (0.14%, 34th percentile).
Remote denial of service in moby/spdystream (Go SPDY/3 library) versions <= v0.5.0 allows an unauthenticated remote peer to crash any service that accepts SPDY connections. By sending a small number of malformed control frames whose attacker-controlled 32-bit counts and lengths are used as unbounded allocation sizes, an attacker forces the process to allocate gigabytes of memory and hit an out-of-memory crash. There is no public exploit identified at time of analysis and EPSS is very low (0.01%), but the flaw is trivially automatable and reaches container-platform components (advisory titled 'DOS on CRI'), so patched v0.5.1 should be adopted where SPDY is exposed.
SQL injection in DataEase, an open-source data visualization and analytics platform, allows an authenticated user to inject arbitrary SQL through the orderDirection sorting parameter on dataset endpoints (/de2api/datasetData/enumValueDs and /de2api/datasetTree/exportDataset) in versions 2.10.20 and below. Because the Order2SQLObj class places the raw value directly into the ORDER BY clause via StringTemplate with no whitelist, an attacker can perform time-based blind data extraction and denial of service. Publicly available exploit code exists (SSVC exploitation: poc); it is not in CISA KEV and the EPSS probability is very low (0.03%). Fixed in version 2.10.21.
Denial of service in the Protobuf PHP library (protobuf-php / composer google/protobuf) allows remote attackers to crash applications that deserialize untrusted Protocol Buffers input by submitting messages containing negative varints or excessively deep nested recursion. All versions below 4.33.6 (and the 5.x line prior to 5.34.0-RC1) are affected; there is no public exploit identified at time of analysis, and EPSS is low at 0.07%, but a vendor patch is available and the issue was reported by Google's CVE coordination team.
Denial of service in fio (Flexible I/O Tester) v3.41 lets a crafted job file crash the process via a NULL pointer dereference: when the fdp_pli option is supplied without an argument, the str_fdp_pli_cb() callback passes a NULL pointer to strdup(), triggering a segmentation fault (CWE-476). Only availability is affected - no code execution or data exposure. It carries a low EPSS score (0.06%, 19th percentile), is not on CISA KEV, and has no public exploit identified at time of analysis, though a referenced gist and upstream GitHub issue #2055 document reproduction.
Buffer overflow in GIMP's GIF image loading component allows arbitrary code execution when a victim opens a specially crafted GIF file. This local‑attack vulnerability (CVSS 3.1: AV:L/PR:N/UI:R) can lead to full compromise of the user's session. No public exploit has been identified, and EPSS exploitation probability is very low (0.01 %).
Remote code execution in Google Chrome on Android versions prior to 147.0.7727.101 is possible through a use-after-free vulnerability in the Payments feature. Attackers who successfully convince users to perform specific UI interactions on a malicious webpage can achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The vulnerability requires high attack complexity and user interaction (CVSS:3.1/AV:N/AC:H/PR:N/UI:R), indicating social engineering is necessary. Google has released Chrome 147.0.7727.101 to address this issue. No evidence of active exploitation (not in CISA KEV) or public proof-of-concept code has been identified at time of analysis.
Arbitrary code execution within Chrome's sandbox affects all versions prior to 147.0.7727.101 via crafted HTML pages exploiting a use-after-free in codec processing. Remote attackers require user interaction (visiting a malicious page) but need no authentication. CVSS 8.8 (High) with network attack vector, low complexity, and high impact across confidentiality, integrity, and availability. Google patched this in the stable channel update released April 15, 2026. No public exploit code or CISA KEV listing identified at time of analysis, though Chromium issue tracker #495996858 indicates vendor-confirmed vulnerability. The sandbox containment limits initial exploitation to Chrome's restricted environment, not direct system compromise.
Remote code execution in Google Chrome via a use-after-free vulnerability in the Cast component allows an attacker who serves a crafted HTML page to execute arbitrary code. The flaw affects Chrome versions prior to 147.0.7727.101 and has a CVSS score of 8.8. At the time of analysis, no active exploitation or public exploit code has been reported, and EPSS indicates a low exploitation probability (0.08%).
A use-after-free vulnerability in Google Chrome's Forms component enables remote code execution within the browser's sandbox when a user visits a malicious web page. The Chromium project rates the severity as High, and the flaw was resolved in version 147.0.7727.101. The low EPSS score (0.08%), absence of CISA KEV listing, and SSVC assessment of no current exploitation suggest limited immediate risk.
Arbitrary code execution in Google Chrome on Android prior to 147.0.7727.101 results from a use-after-free vulnerability in the Permissions component. A remote attacker can exploit this by tricking a user into interacting with a malicious HTML page through specific UI gestures, leading to full compromise of the browser process. No public exploit or active exploitation is reported, and EPSS indicates a low likelihood of widespread exploitation.
Sandbox escape vulnerability in Google Chrome's Dawn (WebGPU implementation) allows attackers who have already compromised the renderer process to escape the browser sandbox and execute arbitrary code on the host system via a malicious HTML page. The flaw, a use-after-free in Dawn, affects Chrome versions prior to 147.0.7727.101. No active exploitation or public proof-of-concept is reported at this time, and the EPSS score (0.02%) indicates low likelihood of widespread exploitation.
Use-after-free in Google Chrome's FileSystem allows a remote attacker to potentially corrupt memory and gain full control of the affected system via a crafted HTML page. The vulnerability, fixed in Chrome 147.0.7727.101, requires user interaction (visiting a malicious site) and has a CVSS score of 8.8, but EPSS indicates a very low exploitation probability (0.03%) and no active exploitation or public exploit code is known.
Unauthenticated database writes in CyberPanel versions before 2.4.4 allow remote attackers to abuse two AI Scanner worker endpoints (/api/ai-scanner/status-webhook and /api/ai-scanner/callback) that ship without authentication checks (CWE-306). Because no credentials are required (CVSS 4.0 PR:N/UI:N), any attacker who can reach the panel can flood the database, corrupt scan-history records, and pollute stored fields, degrading integrity and availability. Publicly available exploit code exists and the flaw was reported by VulnCheck, though EPSS remains low at 0.21% and it is not listed in CISA KEV.
Integer overflow in OP-TEE OS RSA signature encoding crashes the Trusted Execution Environment on platforms with RSA hardware acceleration. Affects versions 3.8.0 through 4.10 when attackers supply cryptographic operations with deliberately undersized RSA moduli, causing memset() to overwrite memory until the TEE crashes. This denial-of-service attack requires no authentication and can be triggered remotely (CVSS AV:N/PR:N), completely disabling the secure-world environment that protects cryptographic keys, biometric data, and DRM operations on affected Arm TrustZone systems. EPSS data not available; no active exploitation confirmed at time of analysis.
Unauthenticated remote attackers can crash Node.js applications using marked versions 18.0.0-18.0.1 by sending a specially crafted 3-byte sequence (tab, vertical tab, newline). The infinite recursion loop exhausts memory and triggers an out-of-memory crash, enabling complete denial of service against any exposed markdown parsing endpoint. Vendor-released patch fixes the vulnerability in version 18.0.2. No public exploit identified at time of analysis, though the attack input is trivially simple and reproducible. CVSS v4.0 8.7 reflects high availability impact with network reachability and no authentication barriers.
Unbounded memory allocation in Eclipse zserio serialization framework allows remote attackers to trigger system crashes via crafted payloads as small as 4-5 bytes, forcing allocations up to 16 GB and causing out-of-memory errors. Affects both C++ and Java runtimes used in Navigation Data Standard (NDS) implementations deployed across millions of vehicles from Toyota, BMW, Volkswagen, Mercedes-Benz, and 39 other automotive manufacturers. Vendor-released patch available in zserio v2.18.1, addressing unchecked length parameters in Array.h, BitStreamReader.h, and Java runtime equivalents. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation without authentication.
Pre-authentication NoSQL injection in Dgraph allows remote unauthenticated attackers to exfiltrate entire databases and modify schemas via crafted JSON mutation keys. The vulnerability exploits unsanitized language tag fields in the addQueryIfUnique function, enabling DQL query injection through specially crafted HTTP POST requests to port 8080. Attackers can extract all database contents including credentials, secrets, and AWS keys with two HTTP requests against default configurations where ACL is disabled. CVSS 9.1 (Critical) with network vector, no authentication required, and low attack complexity. No public exploit code confirmed outside the GitHub advisory, though a complete proof-of-concept with video demonstration exists in the advisory. EPSS data not available for this recent CVE.
Remote unauthenticated attackers can exfiltrate all data from Dgraph databases via DQL injection in the /mutate endpoint's cond parameter. Default configurations with ACL disabled allow single HTTP POST requests to bypass authentication and execute arbitrary read queries, returning complete database contents including credentials, PII, and secrets. The vulnerability exploits unsanitized string concatenation in buildUpsertQuery() where user-supplied cond values are written directly into DQL queries without escaping or validation. Proof-of-concept demonstrates extraction of AWS credentials, GCP service account keys, and user secrets in a single request. No public exploitation confirmed at time of analysis, but POC code publicly available via GitHub advisory. EPSS data not available; CVSS 9.1 indicates critical severity with network vector and no authentication required.
Use-after-free in Linux kernel batman-adv (B.A.T.M.A.N. Advanced mesh networking) allows remote network attackers to trigger memory corruption and potentially execute arbitrary code. The batadv_bla_add_claim() function can prematurely drop a gateway reference while readers still access the pointer, causing netlink dump and claim-check paths to dereference freed memory. Despite CVSS 9.8 critical rating, exploitation probability is low (EPSS 2%, 7th percentile), no active exploitation confirmed, and patches available across kernel stable branches 6.1.169, 6.6.135, 6.12.82, 6.18.23, 6.19.13, and mainline 7.0.
Race condition in Linux kernel memory management allows local attackers with low privileges to corrupt kernel page state, potentially achieving high-impact denial of service, data corruption, or privilege escalation. The vulnerability affects kernel versions 6.6.x through 7.0-rc3, with patches confirmed released for stable branches 6.6.135, 6.12.82, 6.18.23, 6.19.13, and mainline 7.0. EPSS exploitation probability is low (0.02%, 5th percentile), and no public exploit code or active exploitation has been identified at time of analysis. The CVSS vector (AV:L/AC:L/PR:L/UI:N) indicates local access with low attack complexity, while the specific race condition requires precise timing between file mapping and inode size modification operations.
Null pointer dereference in Linux kernel rxrpc subsystem allows remote network attackers to crash the system by sending malformed packets to a client-side connection after a call has been torn down. The flaw affects Linux kernel versions 6.2 onward where the rxrpc client code unconditionally releases a call reference that was never acquired, converting a protocol error into a kernel panic. Vendor patches are available across stable branches (6.6.135, 6.12.82, 6.18.23, 6.19.13, 7.0). EPSS exploitation probability is low (0.02%, 5th percentile) and no public exploit has been identified at time of analysis.
Kernel panic in Linux arm64 memory management causes system crash when handling invalid large leaf page table mappings during DMA bounce buffer operations. ARM64 systems running Linux 7.0-rc4 and earlier (specifically kernels with commit a166563e7ec37 that introduced large block mapping support) crash with translation faults when components like SWIOTLB, secretmem, kfence, or realm DMA attempt to invalidate large leaf mappings. Exploitation requires no special privileges as this is triggered by normal kernel operations during boot or DMA activity. Vendor patches available across stable branches (6.18.24, 6.19.14, 7.0.1). EPSS score is 1st percentile (0.01%) indicating extremely low observed exploitation probability, consistent with this being an availability issue requiring specific ARM64 hardware configurations rather than a remotely exploitable vulnerability.
Use-after-free in Linux kernel blk-cgroup subsystem allows local authenticated users to potentially execute arbitrary code, escalate privileges, or crash the system. The vulnerability occurs in cgwb_release_workfn() when releasing cgroup writeback structures, where a CSS reference is dropped before subsequent dereference, creating a race condition. Meta reports sporadic crashes in production across multiple kernel versions. Patches available for stable branches 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% suggests low widespread exploitation probability, and no active exploitation or public POC identified at time of analysis.
Local privilege escalation and denial of service in the Linux kernel's em28xx USB media driver arises from a use-after-free (CWE-416) in em28xx_v4l2_open(), which reads dev->v4l2 without holding dev->lock. A local attacker who can open the V4L2 device node during a race with the driver's init error path or teardown can trigger a use-after-free on the embedded video_device (via v4l2_fh_init accessing vdev->ctrl_handler) or a NULL dereference in em28xx_resolution_set(). No public exploit identified at time of analysis, and EPSS is very low (0.02%), consistent with a hard-to-win kernel race requiring physical/local USB device presence.
Local privilege escalation and denial of service in the Linux kernel's bcache subsystem stems from a use-after-free of the cached_dev.sb_bio structure; if a cached backing device is stopped while a superblock write is in flight, the freed bio is dereferenced at I/O completion (endio), corrupting kernel memory. Affected systems are those running bcache-backed block devices (observed crashing via librbd/libceph rbd workloads), where a local user with the ability to trigger device teardown during superblock activity can crash the host or potentially corrupt kernel memory. This carries no public exploit identified at time of analysis and an EPSS of just 0.02%, consistent with a hard-to-time race rather than a readily weaponized flaw.
Denial of service via CPU soft lockup in Linux kernel's wlcore Wi-Fi driver (versions 5.10 through 7.0) occurs when memory allocation fails during wireless frame transmission. Incorrect error code return (-EAGAIN instead of -ENOMEM) triggers infinite retry loop while holding critical mutex, causing system unresponsiveness. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.167, 6.6.130, 6.12.78, 6.18.20, 6.19.10, 7.0). CVSS 7.5 (High) reflects network attack vector with no authentication required, though EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV); no public exploit identified at time of analysis.
Use-after-free race condition in Linux kernel Wi-Fi cfg80211 subsystem allows local authenticated users to trigger kernel crashes or potentially execute code. When a nl80211 socket closes while a peer measurement (PMSR) request is active, concurrent interface teardown can leave a scheduled work item (pmsr_free_wk) that later invokes the driver's abort callback on already-freed interface structures. EPSS score of 0.02% (7th percentile) indicates very low probability of exploitation in the wild. Patches available across all supported kernel branches since commit 9bb7e0f24e7e (introduced in Linux 5.0), with fixes released in stable versions 6.1.167, 6.6.130, 6.12.78, 6.18.20, and 6.19.10.
Denial of service in Grafana Tempo allows unauthenticated remote attackers to exhaust server memory by sending trace queries with excessively large result limits. The vulnerability causes unbounded memory allocation during query processing, degrading or halting service availability depending on deployment resources. EPSS data not available; no CISA KEV listing or public exploit identified at time of analysis. Mitigation available through configuration change rather than software patch.
Remote unauthenticated attackers can trigger denial of service in Delta Electronics AS320T industrial automation devices by invoking an undocumented subfunction. The vulnerability allows network-accessible exploitation without credentials against default configurations, potentially disrupting critical industrial control operations. Delta Electronics confirmed the flaw in PCSA-2026-00006, grouped with three other CVEs affecting the same product line.
Denial of service in basic-ftp for Node.js allows remote malicious FTP servers to crash client applications via unbounded memory consumption during directory listing operations. Attackers controlling or compromising an FTP server can send infinite or extremely large listing responses to Client.list() calls, exhausting client memory until process termination. Unauthenticated network attack with low complexity (CVSS:3.1 AV:N/AC:L/PR:N). No public exploit identified at time of analysis, though attack concept is straightforward for anyone operating a malicious FTP server.
A type assertion bug in Kyverno's forEach mutation handler crashes the cluster-wide background controller into CrashLoopBackOff and blocks admission controller operations, causing denial of service for policy-matched resources. Any authenticated user with Policy or ClusterPolicy creation permissions can trigger the crash by creating a malformed policy. The vulnerability affects Kyverno versions prior to 1.17.2 and 1.16.4, is limited to the legacy policy engine (CEL-based policies unaffected), and persists until the malicious policy is deleted. Vendor-released patches available with confirmed fix commits on GitHub.
Resource exhaustion in Open Source Social Network (OSSN) versions prior to 9.0 allows remote unauthenticated attackers to trigger Denial of Service by uploading specially crafted images with extreme pixel dimensions (e.g., 10000×10000). While the compressed file size appears small, server-side decompression and resizing allocates excessive memory and CPU, crashing or degrading service. EPSS exploitation probability data not available, but the attack vector is straightforward (AV:N/AC:L/PR:N) with publicly documented technical details and fix commit available on GitHub. CVSS 8.2 reflects the easy remote exploitation path despite limited confidentiality impact.
Denial of service in libxml2 allows a remote attacker to crash any application that uses the library to XSD-validate an attacker-supplied XML document containing an internal entity reference. The flaw is a CWE-843 type confusion triggered during schema validation, affecting a wide range of Red Hat products that ship libxml2. No public exploit identified at time of analysis, and EPSS is very low (0.01%, 3rd percentile), consistent with SSVC exploitation status of 'none'.
Denial of service in OpenClaw before 2026.3.31 lets remote attackers exhaust image-gateway memory by submitting a decompression bomb - a tiny compressed image that decodes to an enormous pixel count. The pixel-limit guard fails open on the sips backend, so oversized images are decoded before any size check runs. EPSS is very low (0.03%, 9th percentile) and there is no public exploit identified at time of analysis; a vendor patch (2026.3.31) is available.
Denial of service in SWUpdate (versions through 2025.12) allows unauthenticated remote attackers to crash the update service by sending a crafted HTTP POST to the /upload endpoint with a malformed multipart boundary and controlled TCP stream timing. An integer underflow in the bundled Mongoose multipart parser produces an out-of-bounds heap read that corrupts data written to a local IPC socket. No public exploit identified at time of analysis; EPSS is very low (0.03%) and CISA SSVC rates exploitation as none, but a vendor patch commit is available.
Lua code injection in Contour (Kubernetes ingress controller for Envoy) from v1.19.0 through the fixes in v1.31.6/v1.32.5/v1.33.4 lets a low-privileged tenant achieve arbitrary code execution inside the shared Envoy proxy. A user with RBAC rights to create or modify HTTPProxy resources injects Lua via the cookie-rewrite pathRewrite.value field; although the code only runs on the attacker's own route, it executes in shared infrastructure and can steal Envoy's xDS credentials (exposing other tenants' TLS keys) or cause denial of service for co-tenants. No public exploit identified at time of analysis, and EPSS is low (0.07%, 22nd percentile), consistent with the requirement for pre-existing cluster RBAC access.
Denial of service in the Argo Workflows controller (versions 3.6.5 through 4.0.4, plus the 3.7.0-rc1 through 3.7.12 pre-releases) lets any user able to submit a workflow crash-loop the entire controller by attaching a malformed workflows.argoproj.io/pod-gc-strategy pod annotation that contains no '/' separator, triggering an out-of-range index panic in an informer goroutine that sits outside the controller's recover() scope. Because the poisoned pod persists across restarts, the controller enters CrashLoopBackOff and halts all workflow processing cluster-wide until the pod is manually deleted. A working proof-of-concept manifest is published in the GHSA advisory (SSVC exploitation status: poc), but there is no evidence of active exploitation and EPSS is very low at 0.04%.
Sandbox escape in Google Chrome's DevTools component (versions prior to 147.0.7727.117) lets an attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page. Rated High by Chromium and CVSS 9.6, this is a use-after-free (CWE-416) that serves as the second link in a multi-stage exploit chain rather than a standalone remote code execution. No public exploit identified at time of analysis, EPSS is very low (0.03%), and CISA SSVC records no observed exploitation, so it is a patch-and-move-on desktop browser fix rather than an emergency.
Out-of-bounds memory read in the X.Org X server's XKB key types request handling allows a local, authenticated client to disclose adjacent server memory or crash the server (DoS), with higher-impact outcomes possible in certain configurations. The flaw affects the X server component shipped across Red Hat Enterprise Linux 6 through 10 and corresponding SUSE releases, and stems from missing bounds validation on an XKB request. There is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and CISA/SSVC records no known exploitation.
Local privilege-relevant memory corruption in the X.Org X server arises from a use-after-free in the XSYNC fence-triggering path (miSyncTriggerFence()), letting any client with a connection to the display crash the server or corrupt heap memory without user interaction. Rated CVSS 7.8 with total technical impact per CISA SSVC, it currently shows no public exploit identified at time of analysis, no CISA KEV listing, and a very low EPSS of 0.01% (3rd percentile). Because the X server frequently runs with elevated privileges, successful memory corruption could escalate beyond denial of service.
Memory-disclosure and denial-of-service in the X.Org X server arises from an integer underflow (CWE-191) in the XKB compatibility map handling, which lets a client with local or remote X11 access trigger an out-of-bounds buffer read. Any attacker able to open a connection to the display server can crash it or read adjacent server memory, with Red Hat and SUSE rating the technical impact as total; no public exploit identified at time of analysis and EPSS is negligible (0.01%, 2nd percentile). This was reported by Red Hat and affects the X server shipped across Red Hat Enterprise Linux 6 through 10.
Unauthenticated remote file read/write and NTLM coercion in Kofax Capture (rebranded Tungsten Capture) 6.0.0.0 stems from the Ascent Capture Service exposing a deprecated .NET Remoting HTTP channel on TCP/2424 with a default, publicly known endpoint identifier and no authentication. A remote attacker can abuse .NET Remoting object unmarshalling to instantiate a server-side System.Net.WebClient, allowing arbitrary file read/write and coerced NTLMv2 authentication that can cascade into credential theft, denial of service, remote code execution, or lateral movement depending on the service account's privileges. Publicly available exploit code exists (VulnCheck/gist PoC); it is not listed in CISA KEV, and EPSS is low at 0.16% (37th percentile).
Remote denial of service via regular expression attack in GROWI allows unauthenticated network attackers to exhaust server resources by submitting maliciously crafted input strings that trigger catastrophic backtracking in regex processing (CWE-1333). GROWI, Inc.'s collaboration platform is vulnerable to ReDoS with a CVSS 4.0 base score of 8.7 (High), reflecting high availability impact through network-accessible, low-complexity exploitation requiring no privileges or user interaction. No CISA KEV listing or public exploit code identified at time of analysis, though vendor advisory confirms the vulnerability and provides remediation guidance.
HTTP response splitting and denial-of-service in i18next-http-middleware < 3.9.3 allows remote unauthenticated attackers to inject arbitrary HTTP headers or crash Node.js processes via CRLF sequences in the lng parameter. On Node.js < 14.6.0, attackers achieve response splitting enabling session fixation, cache poisoning, and reflected XSS. On Node.js ≥ 14.6.0, malformed headers trigger unhandled ERR_INVALID_CHAR exceptions, returning 500 errors to all concurrent users sharing the affected process. Vendor-released patch available in version 3.9.3. No public exploit identified at time of analysis, though exploitation is trivial given the attack vector (simple query parameter manipulation).
Denial of service in @xmldom/xmldom Node.js XML library allows remote attackers to crash applications via deeply nested XML documents. Seven DOM traversal methods (normalize, serializeToString, getElementsByTagName, cloneNode, importNode, textContent getter, isEqualNode) implement unbounded recursion consuming call stack frames until RangeError exception terminates the process. Exploitation requires no authentication - attackers send a single valid XML payload nested ~5,000-10,000 levels deep to trigger stack exhaustion in any subsequent DOM operation. Browser implementations of identical DOM methods use iterative C++ code and are unaffected. CVSS 8.7 High severity reflects network attack vector with no complexity barriers. Vendor-released patches (0.8.13, 0.9.10) replace all recursive traversals with iterative 'walkDOM' utility consuming heap instead of stack. Legacy unscoped 'xmldom' package (≤0.6.0) remains unfixed.
Remote unauthenticated denial of service crashes Nimiq blockchain nodes by exploiting a protocol state machine flaw. Attackers can force panic conditions in the libp2p discovery handler by opening duplicate protocol substreams, immediately taking peer-to-peer networking offline until manual restart. Vendor-released patch available in version 1.3.0 with no workarounds for unpatched systems, creating urgent upgrade requirement for blockchain node operators.
Remote denial of service in dnsdist allows unauthenticated attackers to crash the DNS load balancer by sending specially crafted DNSCrypt queries that trigger a divide-by-zero error. The vulnerability requires no authentication, low attack complexity, and directly impacts service availability for all DNS traffic routed through affected dnsdist instances. Organizations using DNSCrypt protocol support in dnsdist face immediate risk of service disruption from remote attackers.
Use-after-free in Linux kernel CXL (Compute Express Link) subsystem allows local authenticated attackers to corrupt memory and potentially execute arbitrary code or cause kernel panics. The flaw occurs in cxl_detach_ep() during device removal when parent port references are freed prematurely, before child operations complete. Affects Linux kernel 6.3 through 7.0-rc5; patched in versions 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% indicates low exploitation probability. No active exploitation or public exploit code identified at time of analysis.
Double-free vulnerability in Linux kernel SMC (Shared Memory Communications) splice handling allows local authenticated attackers to trigger use-after-free conditions and kernel panic. The flaw occurs when tee(2) duplicates an SMC pipe buffer: both the original and cloned pipe_buffer share the same smc_spd_priv pointer, causing smc_rx_pipe_buf_release() to free the same memory twice on pipe cleanup. This escalates from KASAN-detected slab-use-after-free to NULL pointer dereference in smc_rx_update_consumer(), resulting in denial of service via kernel crash. Vendor patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS exploitation probability is low (0.02%, 7th percentile) with no public exploit or CISA KEV listing at time of analysis.
Type confusion in Linux kernel team driver allows local authenticated users to trigger memory corruption and potential privilege escalation. The team_setup_by_port() function incorrectly copies header_ops from non-Ethernet lower devices (such as GRE interfaces) without proper context validation, causing callbacks like dev_hard_header() to interpret netdev_priv() as the wrong structure type when processing stacked network topologies (e.g., gre → bond → team). While CVSS rates this 7.8 (High), EPSS probability is very low at 0.02% (5th percentile), and no active exploitation or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0).
Use-after-free in Linux kernel SPI subsystem (fsl_lpspi driver) causes NULL pointer dereference when DMA channels are torn down while SPI transfers are active. Local attackers with low privileges can trigger denial of service or potentially execute arbitrary code on affected systems running Linux kernel versions from 4.10 through 7.0-rc2, particularly impacting embedded and IoT devices using Freescale LPSPI controllers. EPSS score of 0.02% indicates very low observed exploitation probability, and no public exploit code or active exploitation has been identified at time of analysis. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).
Memory exhaustion and kernel crash in Linux kernel's ksmbd SMB server allows remote unauthenticated denial of service via crafted lock requests. The smb2_lock() function contains three critical error-handling defects: memory leaks when vfs_lock_file() returns unexpected errors, stale error propagation in UNLOCK operations, and NULL pointer dereference during rollback when smb_flock_init() allocation fails. CVSS vector indicates network-accessible, low-complexity exploitation requiring no authentication. EPSS score of 0.02% (7th percentile) suggests minimal observed scanning activity, and no KEV listing confirms no widespread exploitation detected. However, the network attack vector (AV:N) and high availability impact (A:H) make this a realistic DoS risk for systems running ksmbd. Vendor patches available across stable kernel series 5.15-6.19.
Use-after-free in Linux kernel's XFS filesystem allows local authenticated users to achieve arbitrary code execution, privilege escalation, or information disclosure. The vulnerability occurs in the XFS Active Item List (AIL) push mechanism where log items can be freed by background reclaim processes while still being dereferenced by tracepoints. Vendor patches are available for kernel versions 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (7th percentile) indicates very low observed exploitation probability in the wild, and no public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.
Race condition in Linux kernel ext4 filesystem allows denial of service through kernel panic when fast commit feature processes incompletely initialized journal inodes. Affects Linux kernel versions from 3.11 through multiple stable branches (5.10.x, 5.15.x, 6.1.x, 6.6.x, 6.12.x, 6.18.x, 6.19.x) prior to patched versions released in early 2025. Vendor patches available across all affected stable branches. EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. Not listed in CISA KEV, and no public exploit code identified at time of analysis. CVSS 8.8 reflects authenticated network attack vector, though real-world risk limited to systems where attackers have filesystem write access and ext4 fast commit is enabled.
Denial of service in Linux kernel ext4 filesystem allows remote attackers to trigger infinite loops and system hangs (143+ second inode lock blocking) via crafted mkdir/mknod operations. The vulnerability stems from incomplete cleanup when extent insertion fails - ext4_ext_map_blocks() reclaims physical blocks without deleting stale extent tree entries, causing reuse of blocks already allocated to xattrs. This triggers infinite loops in ext4_xattr_block_set() that hold inode locks indefinitely. With CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) but EPSS only 0.02% (percentile 7), the network attack vector rating appears inconsistent with typical local filesystem exploitation. Patches available across stable kernel branches 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. No active exploitation confirmed (not in CISA KEV), but tagged for denial-of-service impact.
Use-after-free and descriptor management error in Linux kernel's Intel IDXD DMA engine driver allows NULL pointer dereferences, double completion, or descriptor leaks. The llist_abort_desc() function completes the wrong descriptor object due to a loop cursor bug introduced in commit aa8d18becc0c. Patches released for kernel 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS exploitation probability is very low (0.02%, 5th percentile), and no active exploitation or public exploit code identified. Despite CVSS 9.8 critical rating with network vector, the actual attack surface requires local access to DMA engine subsystems, making the CVSS vector likely inaccurate or context-dependent.
Heap buffer overflow in GNU Binutils XCOFF linker allows arbitrary code execution when a local user processes a malicious object file. Red Hat Enterprise Linux versions 6 through 10 are confirmed affected via CPE data. CVSS 7.8 reflects local attack vector requiring user interaction (opening/linking the crafted file). No active exploitation confirmed (not in CISA KEV), and no public proof-of-concept identified at time of analysis. Real-world risk depends heavily on whether development workflows involve linking untrusted XCOFF files, which is uncommon outside AIX/PowerPC cross-compilation scenarios.
Uncontrolled resource consumption in Progress Telerik UI for AJAX RadAsyncUpload component allows remote unauthenticated attackers to exhaust disk space by uploading files exceeding configured size limits through chunked upload bypass. The vulnerability arises from missing cumulative size validation during chunk reassembly, enabling attackers to circumvent intended upload restrictions. No authentication required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N), making this exploitable against any internet-facing application using affected versions. Patch available in version 2026.1.421. No CISA KEV listing or public exploit code identified at time of analysis, but low attack complexity and no authentication barrier indicate straightforward exploitation potential.
Concurrent DAAP login requests crash OwnTone Server 28.4-29.0 via race condition in session list handling, causing remote denial of service without authentication. Attack complexity is high (CVSS AC:H) but requires no privileges, enabling unauthenticated attackers to flood the /login endpoint and trigger crashes through unsynchronized global state access. Vendor patch available via GitHub commit dca94641; no active exploitation confirmed at time of analysis.
Remote unauthenticated denial of service affects facil.io (all versions prior to commit 5128747) and iodine (all versions before 0.7.59) through malformed JSON input triggering infinite CPU loop. Attackers can send crafted JSON payloads as small as two bytes ('[i') to the `fio_json_parse` function, causing the process to consume 100% of a CPU core indefinitely without crashing or returning an error. This vulnerability allows trivial resource exhaustion against any web service using these frameworks to parse untrusted JSON. EPSS data not available; no confirmed active exploitation (CISA KEV absent), but the attack requires only network access with no authentication and minimal complexity (CVSS AV:N/AC:L/PR:N), making exploitation straightforward once discovered.
Unauthenticated remote attackers can crash free5GC Policy Control Function (PCF) versions before 1.4.3 via repeated HTTP requests to the OAM endpoint over the Service-Based Interface. Each request leaks memory by registering duplicate CORS middleware in the Gin router handler chain, causing progressive memory exhaustion that prevents all User Equipment from establishing 5G sessions. Patched in version 1.4.3 via commit 599803b. EPSS data unavailable; not listed in CISA KEV. CVSS 7.5 High severity reflects network-accessible unauthenticated attack with high availability impact.
Denial-of-service in Oracle Identity Manager Connector (Core component) version 12.2.1.4.0 lets a remote, unauthenticated attacker send network traffic over TCP to hang or repeatedly crash the service, producing a complete availability outage (CVSS 3.1 7.5). Oracle disclosed this in the April 2026 Critical Patch Update; there is no public exploit identified at time of analysis, and EPSS is very low (0.04%). Confidentiality and integrity are unaffected - the impact is purely availability (CWE-400, resource exhaustion).
Denial of service in the Networking component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition allows an unauthenticated, network-based attacker to cause a hang or repeatable crash (complete availability loss) of the affected runtime. The flaw is described by Oracle as easily exploitable via multiple protocols against any application that feeds attacker-controlled data to the vulnerable networking APIs (e.g., an exposed web service). There is no public exploit identified at time of analysis; EPSS is very low (0.04%, 12th percentile) and CISA SSVC lists exploitation status as none, so this is a patch-in-cycle availability issue rather than an active threat.
Remote denial of service in Coturn TURN/STUN server allows unauthenticated attackers to crash ARM64 deployments with a single malformed UDP packet. The vulnerability triggers a fatal SIGBUS signal via misaligned memory access during STUN attribute parsing, requiring no authentication or special configuration. All ARM64 installations of Coturn prior to 4.10.0 are vulnerable to instant process termination. EPSS exploitation probability is not yet available as this is a newly disclosed CVE, but the attack complexity is low (AC:L) and requires no privileges (PR:N), making exploitation trivial once awareness spreads in attacker communities.
Out-of-bounds read in NVIDIA CUDA-Q endpoint allows remote unauthenticated attackers to crash services and disclose sensitive memory contents via malformed network requests. The vulnerability affects an exposed network endpoint with no authentication barrier (CVSS AV:N/AC:L/PR:N/UI:N), enabling trivial exploitation against internet-facing deployments. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis, suggesting exploitation remains theoretical or limited to targeted scenarios.
Unauthenticated remote attackers can access administrative diagnostic endpoints in FreeScout versions prior to 1.8.213, exploiting a predictable MD5 hash derived from the exposed APP_KEY. Attackers can harvest sensitive server information (full path disclosure, process IDs) and trigger resource exhaustion denial-of-service by repeatedly invoking unprotected background tasks. The vulnerability has publicly available exploit code (CVSS E:P), making it immediately actionable for attackers. EPSS data not provided, but the combination of network exposure (AV:N), no authentication required (PR:N), and confirmed POC significantly elevates real-world risk for internet-facing FreeScout installations.
Denial-of-service in Firefox versions prior to 150 allows remote attackers to crash the browser via malformed audio/video content during playback. The vulnerability requires no authentication and minimal attack complexity (CVSS 7.5, AV:N/AC:L/PR:N/UI:N), enabling attackers to render the browser unresponsive or terminated through crafted media files. Mozilla has released Firefox 150 to address this issue. EPSS data not available; no evidence of active exploitation (not in CISA KEV), though SSVC assessment notes the vulnerability is not currently being exploited and is classified as non-automatable with partial technical impact.
Denial-of-service in Firefox's Audio/Video playback component allows remote attackers to crash the browser via network-based exploitation requiring no authentication or user interaction. Mozilla patched the vulnerability in Firefox 150. CVSS 7.5 (High) reflects high availability impact, but SSVC assessment marks it as partial technical impact with no confirmed exploitation, indicating lower real-world priority than critical RCE vulnerabilities. No public exploit code or CISA KEV listing identified.
Signal K Server versions before 2.25.0 allow remote unauthenticated attackers to crash the server via Regular Expression Denial of Service (ReDoS) in WebSocket subscription handling. By injecting unescaped regex metacharacters into the context parameter, attackers trigger catastrophic backtracking that consumes 100% CPU and renders the server completely unresponsive to all API and socket requests. This creates a complete denial of service for marine navigation systems relying on Signal K Server as their central data hub. While EPSS score is low (0.04%, 13th percentile), the trivial exploitation complexity (AV:N/AC:L/PR:N/UI:N) and complete availability impact make this a priority for boat operators running vulnerable versions. No public exploit identified at time of analysis, but the GitHub security advisory provides clear technical details. Vendor-released patch available in version 2.25.0.
Out-of-bounds read in GNU C Library (glibc) versions 2.1.1 through 2.43 during wide character pushback operations can cause application crashes and potential information disclosure. The ungetwc() function incorrectly operates on the regular character buffer instead of the wide-stream buffer due to an implementation bug in _IO_wdefault_pbackfail, leading to reads before allocated memory regions. While CVSS rates this 7.5 High with network vector, EPSS exploitation probability is extremely low (0.02%, 5th percentile), reflecting the highly specialized conditions required: applications must use ungetwc() with character encodings having single-byte/multi-byte overlaps (not standard Unicode sets). No active exploitation confirmed (not in CISA KEV), no public exploit code identified at time of analysis.
Path traversal in Everest Forms (WordPress plugin) allows unauthenticated attackers to read and delete arbitrary files on the server through malicious form submissions containing crafted old_files parameters. Vulnerable versions ≤3.4.4 use regex-based path resolution without canonicalization, enabling attackers to traverse directories, exfiltrate wp-config.php via email attachments (exposing database credentials and authentication salts), and trigger automatic deletion of targeted files post-email. CVSS 8.1 (AV:N/AC:H) reflects the remote vector with high attack complexity. EPSS and KEV status not provided; proof-of-concept details available in Wordfence advisory and plugin source code references.
Control-flow disruption in XiangShan open-source RISC-V processor allows local authenticated attackers to trigger denial of service through malformed CSR operations that fail to properly invoke trap handlers. Affected commits from November 2024 contain improper exception handling in the NewCSR subsystem that can leave the processor core in a hung state when targeting non-existent CSR addresses. GitHub issue #3959 and pull request #3966 document the flaw and proposed fix. EPSS score of 0.02% (5th percentile) indicates very low predicted exploitation probability. No public exploit code identified and not listed in CISA KEV, suggesting primarily theoretical risk limited to specialized RISC-V development environments.
Denial of service and incorrect virtualization-configuration enforcement affect NEMU, the OpenXiangShan RISC-V full-system emulator, because its Hypervisor CSR logic derives henvcfg[7:4] (the CBIE/CBCFE/CBZE cache-block-management fields) from menvcfg[7:4] via an erroneous mask on read. As a result, machine-mode code that writes menvcfg implicitly mutates the hypervisor environment configuration, so guest code running virtualized (V=1) can hit unexpected traps or a denial-of-service when executing cache-block-operation (cbo.*) instructions. No public exploit is identified at time of analysis; EPSS is 0.01% and CISA SSVC lists exploitation as 'none', which conflicts sharply with the 9.8 NVD base score.
Availability-impacting instruction-decoding flaw in OpenXiangShan NEMU (a RISC-V emulator/reference model) before v2025.12.r2 lets crafted RISC-V binaries slip malformed OP-V encodings past the RVV decoder. Because the decoder fails to validate the funct3 field, invalid vector instructions are misinterpreted and executed as vsetvli/vsetivli/vsetvl configuration instructions instead of raising an illegal-instruction exception, causing incorrect trap behavior, architectural-state divergence, and denial of service. There is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and CISA SSVC records exploitation status as none.
OpenXiangShan NEMU emulator's RISC-V Hypervisor extension implementation allows VS-mode guest writes to the sie (supervisor interrupt-enable) CSR to corrupt machine-level mie state, breaking privilege isolation between virtualization layers. Fixed in commit 55295c4 per GitHub PR #938. Despite CVSS 9.8 Critical rating with network attack vector (AV:N), the EPSS score of 0.03% (9th percentile) indicates extremely low observed exploitation probability, and the vulnerability specifically affects RISC-V emulator environments rather than typical network-accessible services. No CISA KEV listing or public exploit identified at time of analysis, suggesting this is a theoretical high-severity issue in specialized research/development contexts rather than an imminent widespread threat.
Uncontrolled memory consumption in monetr 1.12.3 and earlier allows remote unauthenticated attackers to trigger denial of service by sending oversized payloads to the public Stripe webhook endpoint. The vulnerability affects deployments with Stripe webhooks enabled and lacks upstream body-size enforcement. Version 1.12.4 provides a fix. EPSS and KEV data not available; no public exploit confirmed at time of analysis, though the attack method is straightforward (8.2 CVSS reflecting high availability impact with low complexity).
Integer underflow in miniupnpd's SOAPAction header parser triggers out-of-bounds memory reads, enabling adjacent network attackers to crash UPnP-enabled routers or leak sensitive memory contents without authentication. Affects miniupnpd versions prior to 2.3.10. Vendor patch available via commit a0ee71e9fa66. CVSS 7.1 with adjacent network vector (AV:A) indicates attackers must be on the same local network segment as the vulnerable device. No active exploitation confirmed in CISA KEV at time of analysis.
NoSQL injection in FastGPT <4.14.9.5 password authentication allows unauthenticated remote attackers to bypass login controls and access any account, including root administrator, by submitting MongoDB query operators instead of plaintext passwords. The vulnerability stems from missing runtime validation on password fields in the login endpoint. Exploitation requires no special conditions beyond network access to the login endpoint. CVSS 9.8 (Critical) with EPSS data unavailable; no CISA KEV listing or public POC identified at time of analysis, though GitHub security advisory provides technical details that could enable exploit development.
Out-of-bounds read in xrdp RDP server versions ≤0.10.5 allows remote unauthenticated attackers to crash the service or disclose process memory by sending a malformed Confirm Active PDU during RDP capability negotiation. Attack complexity is low but requires user interaction. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis. Vendor-released patch available in version 0.10.6 per GitHub security advisory GHSA-rvh9-9wm3-28c7.
Heap-based buffer overflow in xrdp's NeutrinoRDP module (versions ≤0.10.5) enables malicious downstream RDP servers or MitM attackers to achieve remote code execution or denial of service when proxying RDP sessions. Exploitation requires the victim xrdp server to have the non-default NeutrinoRDP module compiled and enabled (--enable-neutrinordp), and a user must initiate an RDP session through the affected proxy to a malicious server. EPSS data unavailable; no CISA KEV listing indicates targeted rather than widespread exploitation. Fixed in version 0.10.6.
Firebird database server crashes via crafted slice packet exploiting zero-length SDL descriptor validation flaw. Remote unauthenticated attackers can trigger division-by-zero errors in the sdl_desc() function to cause denial of service against Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation with no authentication required. EPSS data not available; no public exploit identified at time of analysis, though technical details in GitHub advisory may facilitate reproduction.
Remote denial-of-service in Firebird Database Server versions prior to 5.0.4, 4.0.7, and 3.0.14 allows unauthenticated network attackers to crash the server via crafted XDR-encoded op_response packets. The xdr_status_vector() function fails to handle isc_arg_cstring status vector types during packet decoding, triggering immediate server termination. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) and CWE-228 (Improper Handling of Syntactically Invalid Structure), this represents a high-severity availability risk for internet-exposed Firebird instances. No active exploitation confirmed, but exploit development is trivial given the low attack complexity.
Null pointer dereference in Firebird SQL server causes remote denial-of-service when unauthenticated attackers send malformed op_crypt_key_callback packets. Firebird versions prior to 5.0.4, 4.0.7, and 3.0.14 are affected. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms trivial remote exploitation requiring no authentication or user interaction, allowing attackers who know only the server's IP and port to crash database services. The integrity impact rating (I:L) suggests potential for limited data corruption alongside the high availability impact. Vendor-released patches are available in versions 5.0.4, 4.0.7, and 3.0.14. No public exploit code or CISA KEV listing identified at time of analysis, though the low attack complexity makes weaponization straightforward.
Remote unauthenticated denial of service in Firebird SQL database server versions prior to 6.0.0/5.0.4/4.0.7/3.0.14 allows attackers to crash the database by sending a malformed op_slice network packet that triggers a null pointer dereference in the SDL_info() function. Attack requires only network access to the database port with no authentication (CVSS AV:N/AC:L/PR:N). No public exploit code identified at time of analysis, and EPSS data not available for this recent CVE. Fixed versions released by vendor across all maintained branches.
Out-of-bounds write in dnsmasq's DHCP split-relay handler allows remote unauthenticated denial of service via crafted BOOTREPLY packets. Affects Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4 when dnsmasq runs with the --dhcp-split-relay option enabled. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) indicates trivial network exploitation, but real-world risk is mitigated by the non-default configuration requirement. No public exploit or active exploitation (CISA KEV) confirmed at time of analysis, though CWE-787 (out-of-bounds write) primitives are well-understood by attackers.
HashiCorp Vault unauthenticated denial-of-service vulnerability allows remote attackers to block critical administrative operations by monopolizing the single operation slot for root token generation and rekey workflows. Affects all Vault Community and Enterprise versions prior to 2.0.0. No active exploitation confirmed (EPSS 3rd percentile), but attack is trivially automatable per CISA SSVC framework. HashiCorp released patches in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0.
Unauthenticated information disclosure (IDOR) in the My Calendar WordPress plugin (versions ≤ 3.7.6) lets remote attackers read calendar events-including private and hidden ones-from any sub-site on a WordPress Multisite network by injecting an arbitrary site ID into the unauthenticated mcjs_action AJAX endpoint. On Single Site installations the same request triggers an uncaught fatal error, giving an unauthenticated denial-of-service vector. Publicly available exploit code exists, though EPSS remains very low (0.01%) and the flaw is not in CISA KEV. Fixed in version 3.7.7.
Unauthenticated remote denial-of-service in ChilliCream's Hot Chocolate GraphQL server for .NET (HotChocolate.Language package) lets any client crash the entire worker process by sending a small, deeply nested GraphQL document. Because the recursive-descent Utf8GraphQLParser has no depth limit, ~40 KB of nested selection sets, object/list values, or list types triggers an uncatchable StackOverflowException that terminates the process, dropping all in-flight HTTP requests, IHostedService background tasks, and WebSocket subscriptions on that worker. No public exploit identified at time of analysis and EPSS is low (0.09%), but the attack is trivial (AC:L, PR:N) and CISA SSVC flags it as automatable, so it is a practical availability threat to internet-facing GraphQL endpoints.
Unauthenticated denial of service in zrok's OAuth-protected proxy shares (openziti/zrok <= 1.1.11 and v2 < 2.0.1) lets a remote attacker crash the proxy process with a single crafted Cookie header. The GetSessionCookie routine reads an attacker-controlled cookie-stripe count and performs make([]string, count) with no upper bound before any authentication, driving gigabyte-scale heap allocations that cause OOM termination or goroutine panics across every share the proxy serves. There is no public exploit identified at time of analysis, and EPSS is low (0.06%), but exploitation is trivially automatable per CISA SSVC.
Denial of service in mcp-framework (npm) versions <= 0.2.21 lets a remote unauthenticated attacker crash any server using the HttpStreamTransport by sending a single oversized HTTP POST to /mcp, exhausting memory. The readRequestBody() function concatenates request-body chunks into a string with no cap, and although a 4MB maxMessageSize config value exists it is never enforced. Publicly available exploit code exists (SSVC 'poc'), a vendor patch shipped in 0.2.22, and EPSS is low (0.14%, 34th percentile).
Remote denial of service in moby/spdystream (Go SPDY/3 library) versions <= v0.5.0 allows an unauthenticated remote peer to crash any service that accepts SPDY connections. By sending a small number of malformed control frames whose attacker-controlled 32-bit counts and lengths are used as unbounded allocation sizes, an attacker forces the process to allocate gigabytes of memory and hit an out-of-memory crash. There is no public exploit identified at time of analysis and EPSS is very low (0.01%), but the flaw is trivially automatable and reaches container-platform components (advisory titled 'DOS on CRI'), so patched v0.5.1 should be adopted where SPDY is exposed.
SQL injection in DataEase, an open-source data visualization and analytics platform, allows an authenticated user to inject arbitrary SQL through the orderDirection sorting parameter on dataset endpoints (/de2api/datasetData/enumValueDs and /de2api/datasetTree/exportDataset) in versions 2.10.20 and below. Because the Order2SQLObj class places the raw value directly into the ORDER BY clause via StringTemplate with no whitelist, an attacker can perform time-based blind data extraction and denial of service. Publicly available exploit code exists (SSVC exploitation: poc); it is not in CISA KEV and the EPSS probability is very low (0.03%). Fixed in version 2.10.21.
Denial of service in the Protobuf PHP library (protobuf-php / composer google/protobuf) allows remote attackers to crash applications that deserialize untrusted Protocol Buffers input by submitting messages containing negative varints or excessively deep nested recursion. All versions below 4.33.6 (and the 5.x line prior to 5.34.0-RC1) are affected; there is no public exploit identified at time of analysis, and EPSS is low at 0.07%, but a vendor patch is available and the issue was reported by Google's CVE coordination team.
Denial of service in fio (Flexible I/O Tester) v3.41 lets a crafted job file crash the process via a NULL pointer dereference: when the fdp_pli option is supplied without an argument, the str_fdp_pli_cb() callback passes a NULL pointer to strdup(), triggering a segmentation fault (CWE-476). Only availability is affected - no code execution or data exposure. It carries a low EPSS score (0.06%, 19th percentile), is not on CISA KEV, and has no public exploit identified at time of analysis, though a referenced gist and upstream GitHub issue #2055 document reproduction.
Buffer overflow in GIMP's GIF image loading component allows arbitrary code execution when a victim opens a specially crafted GIF file. This local‑attack vulnerability (CVSS 3.1: AV:L/PR:N/UI:R) can lead to full compromise of the user's session. No public exploit has been identified, and EPSS exploitation probability is very low (0.01 %).
Remote code execution in Google Chrome on Android versions prior to 147.0.7727.101 is possible through a use-after-free vulnerability in the Payments feature. Attackers who successfully convince users to perform specific UI interactions on a malicious webpage can achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The vulnerability requires high attack complexity and user interaction (CVSS:3.1/AV:N/AC:H/PR:N/UI:R), indicating social engineering is necessary. Google has released Chrome 147.0.7727.101 to address this issue. No evidence of active exploitation (not in CISA KEV) or public proof-of-concept code has been identified at time of analysis.
Arbitrary code execution within Chrome's sandbox affects all versions prior to 147.0.7727.101 via crafted HTML pages exploiting a use-after-free in codec processing. Remote attackers require user interaction (visiting a malicious page) but need no authentication. CVSS 8.8 (High) with network attack vector, low complexity, and high impact across confidentiality, integrity, and availability. Google patched this in the stable channel update released April 15, 2026. No public exploit code or CISA KEV listing identified at time of analysis, though Chromium issue tracker #495996858 indicates vendor-confirmed vulnerability. The sandbox containment limits initial exploitation to Chrome's restricted environment, not direct system compromise.
Remote code execution in Google Chrome via a use-after-free vulnerability in the Cast component allows an attacker who serves a crafted HTML page to execute arbitrary code. The flaw affects Chrome versions prior to 147.0.7727.101 and has a CVSS score of 8.8. At the time of analysis, no active exploitation or public exploit code has been reported, and EPSS indicates a low exploitation probability (0.08%).
A use-after-free vulnerability in Google Chrome's Forms component enables remote code execution within the browser's sandbox when a user visits a malicious web page. The Chromium project rates the severity as High, and the flaw was resolved in version 147.0.7727.101. The low EPSS score (0.08%), absence of CISA KEV listing, and SSVC assessment of no current exploitation suggest limited immediate risk.
Arbitrary code execution in Google Chrome on Android prior to 147.0.7727.101 results from a use-after-free vulnerability in the Permissions component. A remote attacker can exploit this by tricking a user into interacting with a malicious HTML page through specific UI gestures, leading to full compromise of the browser process. No public exploit or active exploitation is reported, and EPSS indicates a low likelihood of widespread exploitation.
Sandbox escape vulnerability in Google Chrome's Dawn (WebGPU implementation) allows attackers who have already compromised the renderer process to escape the browser sandbox and execute arbitrary code on the host system via a malicious HTML page. The flaw, a use-after-free in Dawn, affects Chrome versions prior to 147.0.7727.101. No active exploitation or public proof-of-concept is reported at this time, and the EPSS score (0.02%) indicates low likelihood of widespread exploitation.
Use-after-free in Google Chrome's FileSystem allows a remote attacker to potentially corrupt memory and gain full control of the affected system via a crafted HTML page. The vulnerability, fixed in Chrome 147.0.7727.101, requires user interaction (visiting a malicious site) and has a CVSS score of 8.8, but EPSS indicates a very low exploitation probability (0.03%) and no active exploitation or public exploit code is known.
