Denial Of Service
Monthly
Use-after-free in Zephyr RTOS 4.4.0's Bluetooth ATT host layer (subsys/bluetooth/host/att.c) allows an adjacent unauthenticated peer to crash the Bluetooth host or potentially corrupt live memory by disconnecting while an ATT PDU is in-flight. The tx_meta_data_storage[] array retains a dangling att_chan pointer after L2CAP tears down and frees the channel slab slot, and the deferred att_tx_destroy_work_handler running on the system workqueue dereferences that freed pointer. No pairing or special privileges are required - a routine ATT connection is sufficient to reach the vulnerable code path. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Denial of service in FasterXML jackson-core's non-blocking (async) JSON parser allows unauthenticated network attackers to exhaust JVM heap and CPU by submitting JSON containing arbitrarily long number tokens that bypass the maxNumberLength constraint. Affected deployments are those using the async parser API - particularly reactive frameworks such as Spring WebFlux - running com.fasterxml.jackson.core:jackson-core 2.15.0-2.18.5 or 2.19.0-2.21.0, or tools.jackson.core:jackson-core 3.0.0-3.0.x. Publicly available exploit code exists (PoC JUnit test published in GHSA-72hv-8253-57qq); the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Malformed theme application in the Misskey web client (versions 8.63.0 through pre-2026.5.4) triggers uncontrolled recursion (CWE-674), causing the browser client to slow down significantly or crash entirely. Unauthenticated network-reachable attackers can craft and distribute a malicious theme that, when applied by a victim user, produces a client-side denial of service. No public exploit code has been identified at time of analysis and this vulnerability is not listed in CISA KEV; active exploitation is not confirmed.
ReDoS in Hono's built-in CORS middleware allows unauthenticated remote attackers to stall the JavaScript event loop via crafted OPTIONS preflight requests, degrading or denying service to all concurrent users. The affected npm package `hono` versions below 4.12.34 using the default `cors()` configuration are vulnerable - no authentication, special origin, or user interaction is required. No CISA KEV listing and no dedicated public exploit tool have been identified at time of analysis, but the attack is trivially reproducible given the fully public advisory and commit diff.
Out-of-bounds read in SSSD's NSS responder allows a local user with standard privileges to crash the SSSD process by sending a crafted GETHOSTBYADDR request, causing system-wide denial of authentication and name resolution services. The vulnerable function `sss_nss_protocol_parse_addr()` fails to validate the `addrlen` field against the actual remaining packet body size, enabling heap over-read and process termination. No public exploit code or active exploitation has been identified at time of analysis, and this vulnerability is not listed in CISA KEV.
Stack-based buffer overflow in GIMP's file-png plugin on Red Hat Enterprise Linux 6 through 9 causes the application to crash when a user opens a crafted Animated PNG (APNG) image containing an oversized tRNS chunk, resulting in a Denial of Service limited to the affected user session. Exploitation requires local file access and active user interaction - a remote attacker would rely on social engineering (phishing, malicious download) to deliver the file. No active exploitation has been confirmed by CISA KEV, no public exploit code is identified at time of analysis, and EPSS data is unavailable in source intelligence.
Unbounded PKCS#12 KDF iteration counts in Bouncy Castle for Java allow remote, unauthenticated attackers to cause denial of service by supplying a crafted PKCS#12 file with an arbitrarily large iteration count in MAC or bag-decryption KDF parameters. Any Java application that processes PKCS#12 keystores using bc-java before 1.85, bc-lts-java before 2.73.12, or bc-fja (FIPS) before 1.0.2.7/2.0.2/2.1.3 is affected. No public exploit is identified at time of analysis, but the attack surface is broad given how widely PKCS#12 files are accepted across Java enterprise stacks.
CPU and memory exhaustion in Bouncy Castle Java's BCFKS keystore loader exposes applications to pre-integrity-verification denial of service when processing a crafted keystore file. Any of the three affected library variants - bc-java (before 1.85), bc-lts-java (before 2.73.12), and BC-FJA (before 1.0.2.7, 2.0.2, or 2.1.3 depending on series) - will blindly honour attacker-supplied PBKDF2 iteration counts or scrypt cost parameters read from an untrusted file before the keystore MAC is verified, allowing an adversary to trigger arbitrary CPU or memory consumption at load time. No public exploit code has been identified and the vulnerability is absent from CISA KEV; urgency is rated Amber by the upstream reporter.
Out-of-bounds write in the wifi subsystem of MediaTek MT6890, MT6990, and MT6988 chipsets enables a local denial of service, crashing the wifi component or device. Exploitation requires that the attacker has already obtained System-level privilege on the affected device - an extremely high bar that makes this a post-exploitation nuisance rather than an initial access vector. EPSS sits at 0.13% (3rd percentile), no public exploit code exists, and the vulnerability is not listed in the CISA KEV catalog, all consistent with the substantial privilege prerequisite.
Local denial of service in MediaTek's Audio Hardware Abstraction Layer (HAL) allows a user-privileged process on affected devices to trigger a race condition that renders the system unresponsive. Affected chipsets span two patch families - MT6880/MT6890/MT6988/MT6990 and MT2735/MT2737 - covering a broad range of MediaTek-based mobile and automotive platforms. No active exploitation has been confirmed (not in CISA KEV), and EPSS stands at 0.12% (2nd percentile), reflecting very low real-world exploitation probability at time of analysis.
Out-of-bounds write in the 'med' media processing component of specific MediaTek SoC chipsets (MT6890, MT6988, MT6990, MT2735, MT2737) enables a local attacker with standard user privileges to crash the device, causing a denial of service. The root cause is an incorrect bounds check (CWE-787) that allows a write past allocated buffer boundaries, corrupting memory. No public exploit is identified at time of analysis, and EPSS at 0.15% (4th percentile) combined with SSVC exploitation status of 'none' signals very low real-world exploitation probability.
Out-of-bounds read in MediaTek's ccci (Cross Core Communication Interface) driver on multiple chipsets enables local denial of service by a System-privileged attacker. Affected chipsets include MT6813, MT6988, MT6982VB, MT6986D, and MT6986 - targeting mid-range and flagship Android SoC lines. No public exploit code exists and CISA has not added this to KEV; real-world impact is constrained by the high privilege prerequisite, making this a post-compromise availability risk rather than an initial access vector.
Denial of service in MediaTek WLAN STA (station mode) firmware causes affected devices to become fully unresponsive via uncontrolled logging resource exhaustion (CWE-770). An unauthenticated attacker within wireless proximity can trigger this condition with no user interaction required, targeting chipsets including MT7921, MT7922, MT7902, MT8532, and MT8518S - devices spanning consumer laptops, embedded systems, and IoT hardware. No public exploit or active exploitation has been identified; EPSS of 0.15% (5th percentile) indicates low probabilistic exploitation risk at this time.
Heap buffer overflow in the MediaTek Audio HAL enables a local attacker with user-level privileges to crash the audio subsystem, resulting in a denial of service condition on affected devices. Seven MediaTek chipsets across mobile and automotive platforms are affected, with MediaTek releasing two separate patch IDs addressing the flaw in its August 2026 security bulletin. EPSS at 0.15% (5th percentile), no KEV listing, and a CISA SSVC exploitation status of 'none' collectively indicate negligible real-world exploitation risk at time of analysis; no public exploit code has been identified.
Heap buffer overflow in MediaTek's Audio Hardware Abstraction Layer (HAL) across six chipset families enables local denial of service on affected mobile and automotive platforms. A local user-level process can trigger an out-of-bounds write in the Audio HAL, crashing the audio subsystem with no user interaction required. No public exploit exists and EPSS sits at 0.15% (5th percentile), consistent with SSVC's 'none' exploitation status and the strictly local, availability-only impact profile.
Local denial of service in MediaTek's ccci (Cross Core Communication Interface) kernel driver affects MT6986, MT6988, and MT6813 chipsets through a missing bounds check that enables an out-of-bounds memory access. A local user-privileged attacker - such as a malicious Android application - can crash the kernel, causing device unavailability without requiring user interaction. No public exploit code exists and EPSS probability is 0.16% (6th percentile); SSVC exploitation status is confirmed 'none,' aligning all risk signals toward low immediate threat.
Local privilege escalation in the MediaTek display driver allows an attacker who already holds System-level privileges to further escalate via a use-after-free memory corruption condition, potentially achieving kernel-level access. Seventeen MediaTek SoC models used across Android devices are affected, disclosed in MediaTek's August 2026 security bulletin with Patch ID ALPS11019722. No public exploit code exists and EPSS at 0.14% (4th percentile) confirms negligible current exploitation probability; this vulnerability is not in the CISA KEV catalog.
Out-of-bounds write in MediaTek's Trusted Firmware-A (TFA) component allows a local attacker already holding System-level privilege to crash the device, causing a denial of service. Affected hardware includes MediaTek Dimensity and Helio chipsets MT6986D, MT6986, and MT6982VB. No public exploit code has been identified and CISA KEV does not list this vulnerability, consistent with its low EPSS score of 0.14% and SSVC exploitation status of none.
Out-of-bounds write in the MediaTek Download Agent (DA) firmware component across eight chipset families allows an attacker with physical device access to trigger a local denial of service by sending a crafted payload while the device is in DA mode. Affected chipsets span mobile SoCs (MT6880, MT6890, MT6990, MT6988, MT6986, MT6813) and modem/automotive chipsets (MT2735, MT2737), broadening the potential device footprint across Android smartphones and connected vehicle platforms. No public exploit code exists, EPSS sits at the 6th percentile (0.16%), SSVC confirms no known exploitation, and the physical access prerequisite fundamentally constrains real-world risk.
CPU-exhaustion denial of service in Bouncy Castle for Java affects any server that verifies CMP (Certificate Management Protocol) password-MAC protected messages using PKMACBuilder without an explicit iteration ceiling. The library's PKMACBuilder accepted the iteration count directly from the unauthenticated PBMParameter field in an incoming CMP message with no upper bound, allowing a remote unauthenticated attacker to supply a count near 2^31 and force billions of hash iterations on the target. No active exploitation is confirmed (not in CISA KEV), but the attack is unauthenticated, requires no special configuration beyond standard CMP usage, and a patch is available upstream.
Heap and CPU exhaustion in Bouncy Castle for Java's OpenPGP implementation allows remote unauthenticated attackers to cause denial of service by crafting OpenPGP messages with extreme Argon2 S2K cost parameters. The library honoured attacker-controlled memory, passes (iterations), and parallelism fields embedded in unauthenticated OpenPGP packets before any message authentication could occur, meaning a single crafted packet could instruct the JVM to allocate up to 2^30 KiB (approximately 1 TiB) of heap. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the vulnerability is straightforward to exploit given that the cost parameters are trivially crafted and processed unconditionally.
Denial-of-service via unbounded KDF cost in Bouncy Castle for Java's PKCS#8 / PBES2 decryptors allows remote attackers to exhaust CPU or memory by supplying crafted encrypted key material with extreme KDF parameters. The vulnerability affects bc-java before 1.85, bc-lts-java before 2.73.12, and BC-FJA (bcpkix-fips) across all supported 1.0.X, 2.0.X, and 2.1.X series. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.
Reachable assertion in llama.cpp's Jinja Minja Template Parser crashes the process when processing a maliciously crafted template input. The flaw, located in common/jinja/parser.cpp, is triggered locally by a low-privileged user supplying the input sequence {{9|9|{ to the template engine, causing an unhandled assertion failure and denial of service. A public proof-of-concept exploit has been disclosed; the project was notified via GitHub issue #25282 but has not issued a patch or response as of this writing.
Denial of service in Better Auth (npm) before 1.4.2 lets an unauthenticated remote attacker poison the router's base path when baseURL is not explicitly configured. By sending the very first request after server startup with crafted X-Forwarded-Host and X-Forwarded-Proto headers, the attacker forces every subsequent auth route to return 404 for all users until restart. A working reproduction (curl commands) is published in the GHSA advisory, so publicly available exploit code exists; there is no CISA KEV listing and no public exploit identified as being used in active attacks.
BEAM atom-table exhaustion in ueberauth Guardian 2.0.0-2.4.0 allows denial of service by crashing the entire Erlang/Elixir node and all co-hosted services. The Guardian.Permissions module's encode_permissions!/1 function, installed on every module that invokes 'use Guardian.Permissions', unconditionally calls String.to_atom/1 on every key of a caller-supplied map before any validation. Because the integer-value clause of do_encode_permissions!/2 short-circuits to encoding without validating keys against the configured permission set, an attacker who can supply a permissions map with novel keys - for example via a request body fed into token issuance - permanently consumes BEAM atom-table slots at a rate bounded only by available request throughput. No public exploit or CISA KEV listing is identified at time of analysis; a vendor-released patch (2.4.1) is available.
Guardian's AtomEncoding permission encoder (versions 2.0.0-2.4.1) crashes the BEAM runtime by converting attacker-supplied binary strings directly to permanent atoms via String.to_atom/1, completely bypassing the application's permission allow-list. The BEAM atom table is fixed at approximately 1,048,576 non-garbage-collected entries; exhausting it raises a system_limit error that terminates the entire Erlang node and every application co-hosted on it. This path is only reachable when AtomEncoding is explicitly opted into; no CISA KEV listing or public exploit exists, but the attack is trivially automatable against any network endpoint that routes external permission scope values through encode/3.
Unbounded atom creation in Guardian.Plug.Keys allows any attacker who can route arbitrary string values through Guardian's key derivation functions to permanently exhaust the BEAM virtual machine's atom table, crashing the entire BEAM node and denying service to every application co-hosted on it. All guardian releases from 0.1.0 through 2.4.0 are affected whenever an application passes attacker-influenced data - a tenant identifier, HTTP header, or similar request value - as the key parameter to Guardian.Plug.current_token/2, current_claims/2, current_resource/2, or directly to Guardian.Plug.Keys functions. No public exploit code has been identified at time of analysis, though the attack mechanism is mechanically trivial given that it requires only a stream of distinct HTTP requests to a single vulnerable endpoint.
Serial device redirection in FreeRDP before 3.29.0 exposes RDP clients to a server-induced denial of service via a reachable assertion in the serial channel plugin. A malicious or compromised RDP server can send a crafted IRP_MJ_DEVICE_CONTROL request referencing an unsupported IOCTL with a non-zero OutputBufferLength, causing CommDeviceIoControl() to return BytesReturned=0 and firing the WINPR_ASSERT that aborts the client process. No active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, but the server-controlled trigger makes this straightforward to weaponize against users connecting to untrusted servers with serial redirection enabled.
Denial of service in the axios HTTP client library allows remote attackers to crash server-side request paths by exploiting an incomplete depth-limit bypass introduced as a residual flaw after the prior fix for GHSA-62hf-57xw-28j9. Affected are npm axios versions 0.31.1 through 0.32.x and 1.15.1 through 1.17.x; server-side Node.js applications that accept user-controlled input and pass it to axios form or parameter serialization are the primary concern. No public exploit code has been identified and no CISA KEV listing exists, but the attack mechanism is fully documented in the vendor's GitHub security advisory, materially lowering the exploitation bar for motivated actors.
HTTP/2 streamed upload requests in axios 1.13.0-1.17.x bypass the configured maxBodyLength limit, allowing applications that proxy attacker-controlled streams to an upstream HTTP/2 service to transmit outbound data of arbitrary size. The flaw is constrained to upload-forwarding architectures that explicitly configure a finite maxBodyLength, use the Node.js HTTP adapter with httpVersion: 2, and accept streamed request bodies - conditions common in reverse-proxy and file-upload relay patterns. Impact is limited to resource exhaustion and policy bypass (excess egress costs, upstream quota consumption, limited availability); no public exploit has been identified and the CVE is not listed in CISA KEV.
Uncontrolled recursion in axios's formDataToJSON helper allows remote, unauthenticated attackers to exhaust the JavaScript call stack and deny service to affected Node.js applications. axios versions 0.28.0 through 0.32.x and 1.0.0 through 1.17.x are affected wherever attacker-controlled FormData field names are deserialized with Content-Type: application/json, causing a RangeError that kills the request or terminates the process. No public exploit has been identified at time of analysis, but the GHSA advisory discloses sufficient technical detail - including the exact vulnerable function and the attack payload pattern - for independent reproduction; fixed releases 0.33.0 and 1.18.0 are available.
Out-of-bounds heap read in FreeRDP's UVC H.264 extension-unit parser affects all versions prior to 3.29.0, allowing an attacker with physical USB access to trigger denial of service during camera stream setup. The parser fails to validate descriptor length before accessing the GUID field, enabling a read beyond allocated heap bounds when a malicious USB video camera is connected. No public exploit has been identified, KEV listing is absent, and the CVSS 4.0 score of 2.4 accurately reflects the constrained physical-access attack surface.
Denial of service in guzzlehttp/guzzle versions before 7.15.1 allows a malicious or compromised upstream server to exhaust memory and break outbound requests by returning unlimited, oversized Set-Cookie headers. Guzzle's built-in CookieJar imposes no cap on cookie count or field size, so attacker-controlled cookies accumulate in memory and are later copied into a single outbound Cookie header that exceeds limits in handlers, proxies, or destination servers. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the cross-subdomain cookie scope (e.g., attacker.example.com poisoning cookies for service.example.com) extends the potential blast radius beyond the initially contacted server.
The fetch adapter in axios 1.7.0 through 1.17.x silently skips the maxBodyLength enforcement when a WHATWG ReadableStream body has no determinable Content-Length, allowing attacker-supplied stream data to bypass configured upload size limits. Applications that proxy or relay untrusted stream data via axios with the fetch adapter and rely solely on maxBodyLength as the size guard are exposed to uncontrolled outbound egress and potential exhaustion of upstream API quotas or bandwidth. No public exploit has been identified at time of analysis; CVSS 4.0 scores this at 6.3 with limited availability impact (VA:L) and an attack prerequisite (AT:P) reflecting the specific conditions required.
Uncontrolled recursion in axios's formDataToJSON helper (versions 0.28.0 through <0.33.0 and 1.0.0 through <1.18.0) allows unauthenticated remote attackers to exhaust the JavaScript call stack by submitting FormData with field names containing thousands of nested bracket segments. The vulnerable buildPath() function in lib/helpers/formDataToJSON.js recurses once per path segment with no depth limit, causing a RangeError that, in server-side Node.js applications lacking exception handling, can terminate the process. No active exploitation or public exploit code has been identified at time of analysis; two patched releases (0.33.0 and 1.18.0) are available.
Out-of-bounds read in Zephyr RTOS DHCPv4 client (versions 1.7.0 through 4.4.x) allows an adjacent-network attacker to crash the DHCP client or leak adjacent pointer contents by sending a crafted DHCP reply with a message-type value greater than 8. The defect is a classic sizeof-vs-ARRAY_SIZE confusion: the bounds guard compares a raw msg_type byte against the byte-size of a pointer array (32 or 64, depending on architecture) rather than its element count of 8, so values 9-31/63 bypass the check and cause a wild-pointer dereference inside a debug log call. Exploitation is gated on a non-default build configuration (CONFIG_NET_DHCPV4_LOG_LEVEL_DBG), substantially reducing the real-world attack surface. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Panic-triggered remote denial of service in pion/stun (Go STUN library) versions through 3.1.4 (v3), 2.0.0 (v2), and 1.23.1 (v1) allows an unauthenticated network attacker to crash any application embedding this library by sending a single malformed STUN or ICE Binding-response packet containing a zero-length XOR-MAPPED-ADDRESS attribute. The root cause is a misplaced bounds check in XORMappedAddress.GetFromAs that attempts to index into the value slice before validating minimum length, causing an unrecovered Go runtime panic that terminates the process. No public exploit identified at time of analysis, though the patch PR and test case publicly detail the exact malformed packet structure.
Null byte injection in the free5GC Authentication Server Function (AUSF) v4.2.1 and earlier allows unauthenticated remote attackers to crash Go's URL parser and force HTTP 500 responses on the authentication endpoint, denying authentication service to all legitimate 5G subscribers sharing that AUSF instance. A publicly available Python PoC is included in the vendor's own security advisory, and fuzzing demonstrated a 4.1% trigger rate across nearly 100,000 requests - confirming reliable, scalable exploitation against the default deployment with no special configuration required. No public exploit or CISA KEV listing is confirmed at time of analysis, but the trivially automatable nature of the attack makes it a material risk for 5G core operators.
Memory exhaustion via unbounded configuration file parsing in Pterodactyl Wings prior to v1.13.0 allows a low-privileged game server tenant to crash the Wings daemon. The parsers for JSON, YAML, XML, INI, and text configuration files in parser.go perform no size validation, enabling a malicious or oversized config file to buffer unlimited data into the Wings process heap and trigger an OOM kill. No public exploit is identified at time of analysis, and the vendor-released patch is available in v1.13.0.
Denial of service in the Advantech ECU-1251D industrial communication gateway allows a network-adjacent, high-privilege attacker to send a crafted DNP3 signal to the device's Digital Output address, forcing the DNP3Daemon into an indefinite restart loop and severing SCADA TelWin operator connectivity until a manual restart is performed. The device remains partially reachable via its web panel during the loop, which may create a false impression of operational continuity while SCADA control is lost. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog; the disclosure source is Singapore's Cyber Security Agency (CSA).
Unbounded memory consumption in Google mcp-toolbox versions through 1.4.0 allows unauthenticated remote attackers to crash the service via a single oversized HTTP request. The /mcp endpoint's toolInvokeHandler uses Go's io.ReadAll without any body-size guard - no http.MaxBytesReader, no Content-Length pre-check - so a sufficiently large POST body linearly exhausts host RAM until the OS OOM killer terminates the process. No active exploitation is confirmed (CVSS 4.0 E:U), but the attack requires no authentication and trivial complexity, making any internet-exposed deployment an easy target for denial of service.
node-re2, the Node.js native binding for Google's RE2 regular expression engine, enters an infinite loop and leaks unbounded native memory when String.prototype.match is called with a global pattern capable of producing zero-width (empty string) matches. All versions prior to 1.25.2 are affected; because RE2 executes synchronously within the Node.js event loop thread, the hang is unrecoverable without a process restart, making any service that exposes RE2 global matching to externally-supplied input susceptible to complete denial of service. No public exploit code or CISA KEV listing has been identified at time of analysis, but the trigger condition is mechanically trivial and directly exercisable from patterns confirmed in the vendor's own test additions.
Capsule's node admission webhook can be crashed cluster-wide by a Cluster Admin who stores a malformed regular expression in CapsuleConfiguration's NodeMetadata fields, causing a Go panic via regexp.MustCompile that blocks all subsequent Node create, update, and patch operations. All Capsule versions prior to 0.13.8 are affected, as confirmed by GitHub Security Advisory GHSA-68cj-mvg9-rgm2. No public exploit has been identified at time of analysis, but the Scope:Changed CVSS designation reflects that the crash cascades beyond the vulnerable Capsule component to impair node admission cluster-wide.
Denial of service in IBM Db2 federated server (versions 12.1.0 through 12.1.4) can be triggered by executing non-fenced federated queries, causing the database engine to exhaust resources and become unresponsive. The root cause is CWE-400 (Uncontrolled Resource Consumption) within the in-process federated wrapper execution path. No public exploit has been identified at time of analysis, and IBM has released a patch via their support portal.
Denial of service in Samba's Kerberos KDC password change (kpasswd) service allows authenticated remote attackers to crash the KDC process by submitting specially crafted, malformed ASN.1-encoded password change requests. The server miscalculates the structure size of the incoming request and reads up to six bytes beyond the end of the allocated buffer; when this read strikes unmapped memory, the KDC process terminates rather than simply failing gracefully. No public exploit has been identified and no CISA KEV listing exists, but the disruption of a KDC in an Active Directory or Samba domain environment carries significant operational impact since authentication for the entire domain depends on KDC availability.
Samba's internal DNS server inserts unauthenticated TKEY registration requests into the TKEY name cache before rejecting them, allowing a remote unauthenticated attacker to exhaust the cache by flooding it with arbitrary TKEY names. Eviction of legitimate cache entries blocks TSIG-authenticated DNS query processing, producing a targeted denial of service against Active Directory environments relying on Samba's built-in DNS backend. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available from both Samba upstream and Red Hat.
Regular Expression Denial of Service in Apache Superset's SQL parser (sql_parse.py) allows authenticated attackers to exhaust CPU resources on Superset worker processes by submitting crafted inputs containing pathological character sequences to SQL-processing endpoints. Versions 1.5.0 through 5.0.0 are affected via a vulnerable SQL_REGEX pattern that exhibits catastrophic backtracking under adversarial input. No public exploit code or active exploitation has been identified at time of analysis; the authentication prerequisite meaningfully limits opportunistic attack surface.
Missing brute-force protection on the DFIR-IRIS web application's authentication endpoint exposes version 2.4.26 (and potentially earlier releases) to unlimited credential-stuffing and password-spraying attacks. Unauthenticated remote attackers can submit an unbounded number of login attempts without triggering rate limiting or account lockout, making weak or reused credentials trivially recoverable. DFIR-IRIS is an incident response platform handling sensitive case data, forensic artifacts, and investigation timelines - successful account compromise gives attackers direct access to that material. No public exploit has been identified at time of analysis, and KEV status is not confirmed.
Missing rate-limiting on MFA validation in DFIR-IRIS 2.4.26 allows a remote attacker who possesses valid user credentials to systematically enumerate multi-factor authentication codes until the correct value is found, bypassing the second authentication factor and gaining unauthorized access to the DFIR investigation platform. The CVSS vector scores High confidentiality impact with no integrity or availability penalty, reflecting full read access to sensitive incident response and forensic investigation data. No public exploit code has been identified at time of analysis, and this vulnerability does not appear in the CISA KEV catalog.
Path traversal in the Performance Co-Pilot (PCP) pmproxy logger servlet on Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4 permits unauthenticated remote attackers to create arbitrary files and directories on the host filesystem by supplying a crafted hostname value in requests to the service. The primitive is write-only - no file contents can be read - but an attacker can abuse it to corrupt directory structures or exhaust disk space, leading to denial of service. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
Remote unauthenticated denial of service and memory disclosure in the Performance Co-Pilot (PCP) pmproxy service affects Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. An out-of-bounds read (CWE-125) in the pmLogLoadInDom() function can be triggered by a specially crafted network request, causing the pmproxy process to crash and potentially leaking sensitive data from process memory. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Use-after-free in Chrome's DataTransfer component on Windows exposes process memory to local attackers who can deliver a crafted HTML page to a victim. The flaw affects all Chrome versions on Windows prior to 151.0.7922.72 and results in high-confidence confidentiality loss with no integrity or availability impact. No public exploit code has been identified and EPSS sits at 0.11% (2nd percentile), consistent with CISA SSVC classifying exploitation as 'none' and technical impact as 'partial' - making this a low operational priority despite the High confidentiality CVSS sub-score.
Sandbox escape in Google Chrome's ANGLE graphics layer on Android enables an attacker who has already compromised the renderer process to break out of the Chrome sandbox via a crafted HTML page. Affected versions are all Chrome for Android releases prior to 151.0.7922.72. This is a second-stage exploit primitive requiring a prior renderer compromise; no public exploit code exists and SSVC reports exploitation as none, keeping real-world risk moderate despite the scope-change nature of the flaw.
Use-after-free in the GPU process on macOS enables sandbox escape in Google Chrome versions prior to 151.0.7922.72, but only when an attacker has already achieved renderer process compromise. This is a second-stage exploit primitive - it extends an existing renderer compromise across the sandbox boundary into the GPU process, potentially allowing arbitrary code execution outside Chrome's sandbox on macOS. No public exploit code has been identified and EPSS sits at 0.21% (11th percentile), indicating low observed exploitation probability; however, sandbox escapes are a critical capability for attackers chaining browser exploit kits.
Use-after-free in the Bluetooth component of Google Chrome on Android prior to 151.0.7922.72 enables a sandbox escape for remote attackers who have already achieved renderer process compromise. Exploitation requires delivering a crafted HTML page to a victim user and successfully triggering a memory corruption condition in the Bluetooth subsystem, allowing code execution outside the renderer sandbox. No public exploit code has been identified at time of analysis, and EPSS at 0.21% (11th percentile) indicates low observed exploitation probability; no CISA KEV listing is present.
SQLite 3.41 is vulnerable to use after free in the jsonArrayLengthFunc function.
SQLite 3.41 is vulnerable to use after free in the jsonExtractFunc function. Premature release of parsed JSON object memory leads to subsequent illegal access of freed pointer. Remote attackers can trigger this flaw via specially crafted SQL queries, resulting in service crash and sensitive memory information leakage.
Uncontrolled memory growth in the MCP Ruby SDK (mcp gem) prior to 0.23.0 allows any peer process communicating via stdio to OOM-kill the host Ruby process by sending a continuous byte stream without a newline, exhausting available system memory. Both the server-side MCP::Server::Transports::StdioTransport and client-side MCP::Client::Stdio components are affected, meaning Ruby applications acting as either MCP servers or MCP clients are vulnerable. No public exploit has been identified at time of analysis, and no CISA KEV listing exists, but the attack is mechanically trivial for any process with stdio access to the target.
Uncontrolled resource consumption in Node.js 26.x DNS module allows a network-positioned attacker to trigger a denial-of-service condition by delivering an oversized `resolveAny` DNS reply to an affected application. The vulnerability (CWE-400) was patched in Node.js v26.5.1 released 2026-07-29 as part of a broader security release addressing ten CVEs. No public exploit code and no CISA KEV listing have been identified; the CVSS AC:H metric reflects the prerequisite of controlling or spoofing DNS responses reaching the target process.
Out-of-bounds write buffer handling in the Node.js built-in zlib module (v26.x prior to v26.5.1) fails to throw an exception when a write buffer exceeds valid bounds, enabling a local denial-of-service via process crash or uncontrolled resource consumption. The Node.js security team rated this Medium severity (CVSS 6.2, AV:L) and shipped a fix in v26.5.1 on 2026-07-29 as part of a broader security release addressing ten CVEs. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Buffer overrun in the Apache Traffic Server multiplexer plugin's chunk-decode logic allows network-adjacent attackers who can influence upstream origin responses to cause denial of service across versions 8.0.0 through 10.1.3. The flaw is classified as CWE-787 (Out-of-bounds Write) and is constrained to availability impact only - no code execution or data exposure is indicated. No public exploit or CISA KEV listing has been identified, and the CVSS 3.7 Low score reflects meaningful real-world limitations, primarily the high attack complexity imposed by the upstream-input dependency.
Denial of service in IBM WebSphere Liberty 17.0.0.3 through 26.0.0.8 when the restConnector-2.0 feature is enabled, allowing authenticated remote attackers with low privileges to exhaust server resources via uncontrolled recursion (CWE-674). The attack does not require user interaction and can be conducted over the network, resulting in high availability impact and potential partial confidentiality disclosure. No public exploit or active exploitation has been confirmed at time of analysis.
Use-after-free in the sqlite3 Ruby gem (published as both sqlite3-ruby and sqlite3) versions 2.1.0 through 2.9.4 lets an aggregate function be invoked through a still-open prepared statement after its Database object has been explicitly closed, producing an invalid memory read and a segmentation fault that crashes the Ruby process. Exploitation requires an in-process API-misuse pattern in the host application itself - local, high-complexity, low-privileged per the assessed CVSS:3.1 vector (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L) - with no remote or network vector and no attacker-supplied input. No public exploit identified at time of analysis (EPSS 0.11%, CISA SSVC exploitation: none, Automatable: no); the maintainers classify it as Low severity, describing a reliably reproducible crash after garbage collection rather than a proven denial-of-service or code-execution primitive.
Improper input validation in the BlackBerry UEM Management Console (versions 12.23.0 QF8 and earlier, and 12.22.1 QF7 and earlier) enables unauthenticated remote attackers to trigger arbitrary file download operations and a potential denial of service condition against the console when a Management Console user interacts with attacker-influenced content. The CVSS 4.0 vector reflects high availability impact on the vulnerable system (VA:H) with residual integrity and availability effects on subsequently managed systems (SI:L/SA:L), though the vendor rates confidentiality impact as none (VC:N) - a notable discrepancy given the 'Arbitrary File Download' language in the description that warrants vendor clarification. No public exploit code or active exploitation has been identified; EPSS places this at the 11th percentile (0.21%) and SSVC independently assesses exploitation as none with a non-automatable attack path.
A use-after-free vulnerability in the sqlite3-ruby gem allows an attacker to crash the Ruby process by defining a custom SQLite function with the same name but a different number of arguments or text encoding, leading to an invalid memory read and segmentation fault. The issue affects versions prior to 2.9.5 and was assessed as low severity by the maintainers due to the specific code pattern required for exploitation.
Remote unauthenticated denial of service in gopacket <= 1.6.0 via a single crafted sFlow UDP datagram that triggers an unbounded memory allocation of up to 16 GiB, causing the parsing process to be OOM-killed. Affected services include any network telemetry collector or application that uses gopacket’s sFlow decoder without additional validation. A proof-of-concept exploit exists and can crash the process with just a 104-byte packet.
Remote denial-of-service in the gopacket library's Diameter AVP decoder allows unauthenticated attackers to trigger a ~4 GiB memory allocation per crafted packet, causing OOM kill after two messages under memory constraints. The flaw affects gopacket ≤1.6.0 (latest before fix), and publicly available exploit code demonstrates end-to-end exploitation against a collector with a 256 MB memory cap. No active exploitation is currently reported.
Uncontrolled resource consumption in Apache Tomcat's default WebSocket chat example allows remote attackers to cause denial of service. Affected versions include 11.0.0-M20 through 11.0.24, 10.1.24 through 10.1.57, and 9.0.89 through 9.0.120; users who have removed the examples web application as recommended are not impacted. No public exploit code or active exploitation is reported.
Processing specially crafted graph data in Pivotick can lead to unreliable visualizations, corrupted cycle detection, and client-side denial-of-service. An attacker can craft node identifiers that collide with Object.prototype properties ('constructor', 'toString', '__proto__'), causing prototype pollution and logic errors. No known active exploitation or public exploit code exists, but the vulnerability is trivially triggered by user interaction.
Unauthenticated disabling of the ACME service in Dogtag PKI allows persistent denial of service via URL manipulation. By appending a trailing slash to admin-only enable/disable endpoints, an attacker can bypass the Tomcat authentication constraint while RESTEasy routes the request, enabling unauthorized toggling. No public exploit or active exploitation has been reported.
Memory exhaustion in Lookyloo 1.40.0 and earlier allows attackers to crash web or worker processes by submitting a crafted ZIP capture archive or gzip-compressed HAR payload that expands to an enormous size when decompressed in memory, degrading or taking the instance offline until processes are restarted. Both the full capture-archive import path and the API submission path that accepts gzip-compressed HAR data are affected, and although authentication requirements are not confirmed for every entry point, the published CVSS:4.0 vector records PR:N for the API path. The vulnerability is vendor-patched via upstream commit 96589da (a 1 GB uncompressed ceiling plus size-bounded zlib/gzip decompression), there is no CISA KEV listing, no public exploit code identified at time of analysis, and the EPSS score is a low 0.25% (17th percentile); this is a genuine but modest-priority denial-of-service issue rather than a high-urgency threat.
Resource exhaustion in Ninenines Cowboy's HTTP/1.1 handler allows unauthenticated remote attackers to cause denial of service by sending many header lines with the same name, bypassing the max_headers limit due to counting distinct names instead of total lines. Affects Cowboy versions 2.0.0-pre.4 to 2.17.x; fixed in 2.18.0. No public exploit or active exploitation has been reported at this time.
Safari and WebKit-based apps across Apple platforms crash when a user visits a specially crafted website, due to a state management flaw (CWE-400: Uncontrolled Resource Consumption) in versions prior to 26.6. Affected platforms include Safari on macOS Tahoe, iOS 26, iPadOS 26, and visionOS 26. No confidentiality or integrity impact is present - the consequence is an app-level denial-of-service. No public exploit code exists and CISA SSVC confirms no active exploitation, with EPSS at 0.16% (6th percentile), indicating very low exploitation likelihood at time of analysis.
Denial of service in macOS versions prior to Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6 allows a local malicious app to trigger memory corruption and crash the system. Exploitation requires user interaction to run the app; no active exploitation is known (not in CISA KEV) and EPSS indicates a very low probability (0.16%). Apple has released updates to address the logic issue.
Local denial of service in macOS allows a malicious app to trigger unexpected system termination via memory exhaustion. Affects macOS Sequoia prior to 15.7.8, macOS Sonoma prior to 14.8.8, and macOS Tahoe prior to 26.6. No active exploitation or public exploit identified; EPSS probability is low (0.16%).
Denial-of-service in multiple Apple operating systems allows a local network attacker to cause resource exhaustion and system unavailability. The vulnerability is addressed in iOS 26.6, iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, and watchOS 26.6. No public exploit or active exploitation has been identified at this time, and the EPSS score is low (0.17%).
Unexpected Safari crash via use-after-free when processing maliciously crafted web content affects Safari 26.6 and earlier on all Apple platforms. This denial-of-service condition requires user interaction to open a malicious webpage; no public exploit identified and EPSS probability is low (0.14%).
Denial of service in macOS Tahoe fixed by removing vulnerable code. A local attacker with low privileges can cause a denial-of-service condition. No active exploitation or public exploit known, and the low EPSS score (0.14%) indicates limited real-world risk.
An integer overflow in GIMP's file-sgi plugin, triggered by a crafted RLE-compressed SGI image, causes denial of service by crashing the plugin. The vulnerability affects GIMP versions with the file-sgi plugin and requires a user to open a malicious image file. No public exploit or active exploitation is known at this time; the issue is being tracked by GNOME and Red Hat.
Denial of service in Zephyr's Synopsys DesignWare I2C driver (slave mode) enables an I2C master on the same physical bus to cause permanent failure of the write_requested() callback due to a missing START_DET interrupt enable. This halts all subsequent write transactions and desynchronizes higher-layer framing until device reset. No public exploit identified; patch available from vendor.
Denial of service in HDF5 caused by a NULL pointer dereference when processing a crafted HDF5 file with an invalid variable-length datatype attribute. The vulnerability affects all versions of HDF5 and can be triggered by a user opening a malicious file, leading to application crash. Publicly available exploit code exists per CVSS metric.
Heap-based buffer overflow in HDF5 through 2.1.1 enables attackers to crash applications and potentially corrupt data by providing a crafted HDF5 file. The flaw lies in the shared‑message list‑index deserializer (SOHM), allowing out‑of‑bounds heap reads and writes when a num_messages field exceeds the declared list_max. No active exploitation has been reported, but the issue is publicly documented and a proof‑of‑concept may exist in the linked issue.
Denial of service vulnerability in Mattermost allows authenticated users to exhaust server resources by uploading crafted animated GIFs as custom emoji. Affects versions 10.11.x, 11.6.x, 11.7.x, and 11.8.x up to certain patch levels. No active exploitation or public exploit is known, but patches are available from the vendor.
Denial of service in Mattermost 10.11.x through 11.8.x allows authenticated users with file-upload permission to degrade file-upload performance for all users by exploiting unbounded resource consumption during server-side document extraction. Attackers can repeatedly upload small documents that are expensive to extract, saturating the extraction worker pool and causing service degradation. No active exploitation or public exploit code is reported, but the low attack complexity and minimal privileges make this an accessible DoS vector.
Out-of-bounds heap read in GNU Binutils linker when processing 32-bit XCOFF files allows local attackers to disclose heap memory and cause denial of service. Affects Red Hat Enterprise Linux 6 through 10, Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation identified at time of analysis; EPSS data unavailable.
Local denial of service in ggml-org whisper.cpp 95ea8f9b via reachable assertion in ggml_ftype_to_ggml_type function. A local attacker with low privileges can cause a crash by supplying an invalid ftype argument. No public exploit identified; no patch available as vendor has not responded to issue report.
Denial-of-service in the Mercusys MB115-4G router's web interface allows unauthenticated attackers to crash the administration service by sending a crafted request to the /cgi/login endpoint. A stack buffer overflow in the http_gdpr_decrypt function corrupts memory and halts the httpd process, leaving the device operational but unmanageable through the web UI. A vendor patch is available; no public exploit or active exploitation has been identified.
Integer overflow in the print_string_ptr() function of the cJSON library on 32-bit platforms causes a heap buffer overflow when processing crafted JSON strings with approximately 858,993,460 control characters. Applications using cJSON_PrintBuffered() with a pre-allocated buffer are vulnerable, potentially leading to remote code execution, information disclosure, or denial of service. No public exploit or active exploitation has been identified at the time of analysis.
Remote denial of service in llama.cpp allows unauthenticated attackers to exhaust server resources via crafted JSON schema inputs that trigger unbounded recursion in the JSON-schema-to-GBNF conversion routine. Affected versions include commit e15efe0 and prior. A fix exists in a pending pull request; no active exploitation reported.
Denial of service in ggml-org llama.cpp allows remote attackers to crash the application by sending a crafted JSON schema that triggers a null pointer dereference in the _visit_pattern function. No authentication or user interaction is required, and all versions up to the affected commits d006858/e15efe0 are vulnerable. The fix is pending merge; no public exploit code has been identified.
Use-after-free in Zephyr RTOS 4.4.0's Bluetooth ATT host layer (subsys/bluetooth/host/att.c) allows an adjacent unauthenticated peer to crash the Bluetooth host or potentially corrupt live memory by disconnecting while an ATT PDU is in-flight. The tx_meta_data_storage[] array retains a dangling att_chan pointer after L2CAP tears down and frees the channel slab slot, and the deferred att_tx_destroy_work_handler running on the system workqueue dereferences that freed pointer. No pairing or special privileges are required - a routine ATT connection is sufficient to reach the vulnerable code path. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Denial of service in FasterXML jackson-core's non-blocking (async) JSON parser allows unauthenticated network attackers to exhaust JVM heap and CPU by submitting JSON containing arbitrarily long number tokens that bypass the maxNumberLength constraint. Affected deployments are those using the async parser API - particularly reactive frameworks such as Spring WebFlux - running com.fasterxml.jackson.core:jackson-core 2.15.0-2.18.5 or 2.19.0-2.21.0, or tools.jackson.core:jackson-core 3.0.0-3.0.x. Publicly available exploit code exists (PoC JUnit test published in GHSA-72hv-8253-57qq); the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Malformed theme application in the Misskey web client (versions 8.63.0 through pre-2026.5.4) triggers uncontrolled recursion (CWE-674), causing the browser client to slow down significantly or crash entirely. Unauthenticated network-reachable attackers can craft and distribute a malicious theme that, when applied by a victim user, produces a client-side denial of service. No public exploit code has been identified at time of analysis and this vulnerability is not listed in CISA KEV; active exploitation is not confirmed.
ReDoS in Hono's built-in CORS middleware allows unauthenticated remote attackers to stall the JavaScript event loop via crafted OPTIONS preflight requests, degrading or denying service to all concurrent users. The affected npm package `hono` versions below 4.12.34 using the default `cors()` configuration are vulnerable - no authentication, special origin, or user interaction is required. No CISA KEV listing and no dedicated public exploit tool have been identified at time of analysis, but the attack is trivially reproducible given the fully public advisory and commit diff.
Out-of-bounds read in SSSD's NSS responder allows a local user with standard privileges to crash the SSSD process by sending a crafted GETHOSTBYADDR request, causing system-wide denial of authentication and name resolution services. The vulnerable function `sss_nss_protocol_parse_addr()` fails to validate the `addrlen` field against the actual remaining packet body size, enabling heap over-read and process termination. No public exploit code or active exploitation has been identified at time of analysis, and this vulnerability is not listed in CISA KEV.
Stack-based buffer overflow in GIMP's file-png plugin on Red Hat Enterprise Linux 6 through 9 causes the application to crash when a user opens a crafted Animated PNG (APNG) image containing an oversized tRNS chunk, resulting in a Denial of Service limited to the affected user session. Exploitation requires local file access and active user interaction - a remote attacker would rely on social engineering (phishing, malicious download) to deliver the file. No active exploitation has been confirmed by CISA KEV, no public exploit code is identified at time of analysis, and EPSS data is unavailable in source intelligence.
Unbounded PKCS#12 KDF iteration counts in Bouncy Castle for Java allow remote, unauthenticated attackers to cause denial of service by supplying a crafted PKCS#12 file with an arbitrarily large iteration count in MAC or bag-decryption KDF parameters. Any Java application that processes PKCS#12 keystores using bc-java before 1.85, bc-lts-java before 2.73.12, or bc-fja (FIPS) before 1.0.2.7/2.0.2/2.1.3 is affected. No public exploit is identified at time of analysis, but the attack surface is broad given how widely PKCS#12 files are accepted across Java enterprise stacks.
CPU and memory exhaustion in Bouncy Castle Java's BCFKS keystore loader exposes applications to pre-integrity-verification denial of service when processing a crafted keystore file. Any of the three affected library variants - bc-java (before 1.85), bc-lts-java (before 2.73.12), and BC-FJA (before 1.0.2.7, 2.0.2, or 2.1.3 depending on series) - will blindly honour attacker-supplied PBKDF2 iteration counts or scrypt cost parameters read from an untrusted file before the keystore MAC is verified, allowing an adversary to trigger arbitrary CPU or memory consumption at load time. No public exploit code has been identified and the vulnerability is absent from CISA KEV; urgency is rated Amber by the upstream reporter.
Out-of-bounds write in the wifi subsystem of MediaTek MT6890, MT6990, and MT6988 chipsets enables a local denial of service, crashing the wifi component or device. Exploitation requires that the attacker has already obtained System-level privilege on the affected device - an extremely high bar that makes this a post-exploitation nuisance rather than an initial access vector. EPSS sits at 0.13% (3rd percentile), no public exploit code exists, and the vulnerability is not listed in the CISA KEV catalog, all consistent with the substantial privilege prerequisite.
Local denial of service in MediaTek's Audio Hardware Abstraction Layer (HAL) allows a user-privileged process on affected devices to trigger a race condition that renders the system unresponsive. Affected chipsets span two patch families - MT6880/MT6890/MT6988/MT6990 and MT2735/MT2737 - covering a broad range of MediaTek-based mobile and automotive platforms. No active exploitation has been confirmed (not in CISA KEV), and EPSS stands at 0.12% (2nd percentile), reflecting very low real-world exploitation probability at time of analysis.
Out-of-bounds write in the 'med' media processing component of specific MediaTek SoC chipsets (MT6890, MT6988, MT6990, MT2735, MT2737) enables a local attacker with standard user privileges to crash the device, causing a denial of service. The root cause is an incorrect bounds check (CWE-787) that allows a write past allocated buffer boundaries, corrupting memory. No public exploit is identified at time of analysis, and EPSS at 0.15% (4th percentile) combined with SSVC exploitation status of 'none' signals very low real-world exploitation probability.
Out-of-bounds read in MediaTek's ccci (Cross Core Communication Interface) driver on multiple chipsets enables local denial of service by a System-privileged attacker. Affected chipsets include MT6813, MT6988, MT6982VB, MT6986D, and MT6986 - targeting mid-range and flagship Android SoC lines. No public exploit code exists and CISA has not added this to KEV; real-world impact is constrained by the high privilege prerequisite, making this a post-compromise availability risk rather than an initial access vector.
Denial of service in MediaTek WLAN STA (station mode) firmware causes affected devices to become fully unresponsive via uncontrolled logging resource exhaustion (CWE-770). An unauthenticated attacker within wireless proximity can trigger this condition with no user interaction required, targeting chipsets including MT7921, MT7922, MT7902, MT8532, and MT8518S - devices spanning consumer laptops, embedded systems, and IoT hardware. No public exploit or active exploitation has been identified; EPSS of 0.15% (5th percentile) indicates low probabilistic exploitation risk at this time.
Heap buffer overflow in the MediaTek Audio HAL enables a local attacker with user-level privileges to crash the audio subsystem, resulting in a denial of service condition on affected devices. Seven MediaTek chipsets across mobile and automotive platforms are affected, with MediaTek releasing two separate patch IDs addressing the flaw in its August 2026 security bulletin. EPSS at 0.15% (5th percentile), no KEV listing, and a CISA SSVC exploitation status of 'none' collectively indicate negligible real-world exploitation risk at time of analysis; no public exploit code has been identified.
Heap buffer overflow in MediaTek's Audio Hardware Abstraction Layer (HAL) across six chipset families enables local denial of service on affected mobile and automotive platforms. A local user-level process can trigger an out-of-bounds write in the Audio HAL, crashing the audio subsystem with no user interaction required. No public exploit exists and EPSS sits at 0.15% (5th percentile), consistent with SSVC's 'none' exploitation status and the strictly local, availability-only impact profile.
Local denial of service in MediaTek's ccci (Cross Core Communication Interface) kernel driver affects MT6986, MT6988, and MT6813 chipsets through a missing bounds check that enables an out-of-bounds memory access. A local user-privileged attacker - such as a malicious Android application - can crash the kernel, causing device unavailability without requiring user interaction. No public exploit code exists and EPSS probability is 0.16% (6th percentile); SSVC exploitation status is confirmed 'none,' aligning all risk signals toward low immediate threat.
Local privilege escalation in the MediaTek display driver allows an attacker who already holds System-level privileges to further escalate via a use-after-free memory corruption condition, potentially achieving kernel-level access. Seventeen MediaTek SoC models used across Android devices are affected, disclosed in MediaTek's August 2026 security bulletin with Patch ID ALPS11019722. No public exploit code exists and EPSS at 0.14% (4th percentile) confirms negligible current exploitation probability; this vulnerability is not in the CISA KEV catalog.
Out-of-bounds write in MediaTek's Trusted Firmware-A (TFA) component allows a local attacker already holding System-level privilege to crash the device, causing a denial of service. Affected hardware includes MediaTek Dimensity and Helio chipsets MT6986D, MT6986, and MT6982VB. No public exploit code has been identified and CISA KEV does not list this vulnerability, consistent with its low EPSS score of 0.14% and SSVC exploitation status of none.
Out-of-bounds write in the MediaTek Download Agent (DA) firmware component across eight chipset families allows an attacker with physical device access to trigger a local denial of service by sending a crafted payload while the device is in DA mode. Affected chipsets span mobile SoCs (MT6880, MT6890, MT6990, MT6988, MT6986, MT6813) and modem/automotive chipsets (MT2735, MT2737), broadening the potential device footprint across Android smartphones and connected vehicle platforms. No public exploit code exists, EPSS sits at the 6th percentile (0.16%), SSVC confirms no known exploitation, and the physical access prerequisite fundamentally constrains real-world risk.
CPU-exhaustion denial of service in Bouncy Castle for Java affects any server that verifies CMP (Certificate Management Protocol) password-MAC protected messages using PKMACBuilder without an explicit iteration ceiling. The library's PKMACBuilder accepted the iteration count directly from the unauthenticated PBMParameter field in an incoming CMP message with no upper bound, allowing a remote unauthenticated attacker to supply a count near 2^31 and force billions of hash iterations on the target. No active exploitation is confirmed (not in CISA KEV), but the attack is unauthenticated, requires no special configuration beyond standard CMP usage, and a patch is available upstream.
Heap and CPU exhaustion in Bouncy Castle for Java's OpenPGP implementation allows remote unauthenticated attackers to cause denial of service by crafting OpenPGP messages with extreme Argon2 S2K cost parameters. The library honoured attacker-controlled memory, passes (iterations), and parallelism fields embedded in unauthenticated OpenPGP packets before any message authentication could occur, meaning a single crafted packet could instruct the JVM to allocate up to 2^30 KiB (approximately 1 TiB) of heap. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the vulnerability is straightforward to exploit given that the cost parameters are trivially crafted and processed unconditionally.
Denial-of-service via unbounded KDF cost in Bouncy Castle for Java's PKCS#8 / PBES2 decryptors allows remote attackers to exhaust CPU or memory by supplying crafted encrypted key material with extreme KDF parameters. The vulnerability affects bc-java before 1.85, bc-lts-java before 2.73.12, and BC-FJA (bcpkix-fips) across all supported 1.0.X, 2.0.X, and 2.1.X series. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.
Reachable assertion in llama.cpp's Jinja Minja Template Parser crashes the process when processing a maliciously crafted template input. The flaw, located in common/jinja/parser.cpp, is triggered locally by a low-privileged user supplying the input sequence {{9|9|{ to the template engine, causing an unhandled assertion failure and denial of service. A public proof-of-concept exploit has been disclosed; the project was notified via GitHub issue #25282 but has not issued a patch or response as of this writing.
Denial of service in Better Auth (npm) before 1.4.2 lets an unauthenticated remote attacker poison the router's base path when baseURL is not explicitly configured. By sending the very first request after server startup with crafted X-Forwarded-Host and X-Forwarded-Proto headers, the attacker forces every subsequent auth route to return 404 for all users until restart. A working reproduction (curl commands) is published in the GHSA advisory, so publicly available exploit code exists; there is no CISA KEV listing and no public exploit identified as being used in active attacks.
BEAM atom-table exhaustion in ueberauth Guardian 2.0.0-2.4.0 allows denial of service by crashing the entire Erlang/Elixir node and all co-hosted services. The Guardian.Permissions module's encode_permissions!/1 function, installed on every module that invokes 'use Guardian.Permissions', unconditionally calls String.to_atom/1 on every key of a caller-supplied map before any validation. Because the integer-value clause of do_encode_permissions!/2 short-circuits to encoding without validating keys against the configured permission set, an attacker who can supply a permissions map with novel keys - for example via a request body fed into token issuance - permanently consumes BEAM atom-table slots at a rate bounded only by available request throughput. No public exploit or CISA KEV listing is identified at time of analysis; a vendor-released patch (2.4.1) is available.
Guardian's AtomEncoding permission encoder (versions 2.0.0-2.4.1) crashes the BEAM runtime by converting attacker-supplied binary strings directly to permanent atoms via String.to_atom/1, completely bypassing the application's permission allow-list. The BEAM atom table is fixed at approximately 1,048,576 non-garbage-collected entries; exhausting it raises a system_limit error that terminates the entire Erlang node and every application co-hosted on it. This path is only reachable when AtomEncoding is explicitly opted into; no CISA KEV listing or public exploit exists, but the attack is trivially automatable against any network endpoint that routes external permission scope values through encode/3.
Unbounded atom creation in Guardian.Plug.Keys allows any attacker who can route arbitrary string values through Guardian's key derivation functions to permanently exhaust the BEAM virtual machine's atom table, crashing the entire BEAM node and denying service to every application co-hosted on it. All guardian releases from 0.1.0 through 2.4.0 are affected whenever an application passes attacker-influenced data - a tenant identifier, HTTP header, or similar request value - as the key parameter to Guardian.Plug.current_token/2, current_claims/2, current_resource/2, or directly to Guardian.Plug.Keys functions. No public exploit code has been identified at time of analysis, though the attack mechanism is mechanically trivial given that it requires only a stream of distinct HTTP requests to a single vulnerable endpoint.
Serial device redirection in FreeRDP before 3.29.0 exposes RDP clients to a server-induced denial of service via a reachable assertion in the serial channel plugin. A malicious or compromised RDP server can send a crafted IRP_MJ_DEVICE_CONTROL request referencing an unsupported IOCTL with a non-zero OutputBufferLength, causing CommDeviceIoControl() to return BytesReturned=0 and firing the WINPR_ASSERT that aborts the client process. No active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, but the server-controlled trigger makes this straightforward to weaponize against users connecting to untrusted servers with serial redirection enabled.
Denial of service in the axios HTTP client library allows remote attackers to crash server-side request paths by exploiting an incomplete depth-limit bypass introduced as a residual flaw after the prior fix for GHSA-62hf-57xw-28j9. Affected are npm axios versions 0.31.1 through 0.32.x and 1.15.1 through 1.17.x; server-side Node.js applications that accept user-controlled input and pass it to axios form or parameter serialization are the primary concern. No public exploit code has been identified and no CISA KEV listing exists, but the attack mechanism is fully documented in the vendor's GitHub security advisory, materially lowering the exploitation bar for motivated actors.
HTTP/2 streamed upload requests in axios 1.13.0-1.17.x bypass the configured maxBodyLength limit, allowing applications that proxy attacker-controlled streams to an upstream HTTP/2 service to transmit outbound data of arbitrary size. The flaw is constrained to upload-forwarding architectures that explicitly configure a finite maxBodyLength, use the Node.js HTTP adapter with httpVersion: 2, and accept streamed request bodies - conditions common in reverse-proxy and file-upload relay patterns. Impact is limited to resource exhaustion and policy bypass (excess egress costs, upstream quota consumption, limited availability); no public exploit has been identified and the CVE is not listed in CISA KEV.
Uncontrolled recursion in axios's formDataToJSON helper allows remote, unauthenticated attackers to exhaust the JavaScript call stack and deny service to affected Node.js applications. axios versions 0.28.0 through 0.32.x and 1.0.0 through 1.17.x are affected wherever attacker-controlled FormData field names are deserialized with Content-Type: application/json, causing a RangeError that kills the request or terminates the process. No public exploit has been identified at time of analysis, but the GHSA advisory discloses sufficient technical detail - including the exact vulnerable function and the attack payload pattern - for independent reproduction; fixed releases 0.33.0 and 1.18.0 are available.
Out-of-bounds heap read in FreeRDP's UVC H.264 extension-unit parser affects all versions prior to 3.29.0, allowing an attacker with physical USB access to trigger denial of service during camera stream setup. The parser fails to validate descriptor length before accessing the GUID field, enabling a read beyond allocated heap bounds when a malicious USB video camera is connected. No public exploit has been identified, KEV listing is absent, and the CVSS 4.0 score of 2.4 accurately reflects the constrained physical-access attack surface.
Denial of service in guzzlehttp/guzzle versions before 7.15.1 allows a malicious or compromised upstream server to exhaust memory and break outbound requests by returning unlimited, oversized Set-Cookie headers. Guzzle's built-in CookieJar imposes no cap on cookie count or field size, so attacker-controlled cookies accumulate in memory and are later copied into a single outbound Cookie header that exceeds limits in handlers, proxies, or destination servers. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the cross-subdomain cookie scope (e.g., attacker.example.com poisoning cookies for service.example.com) extends the potential blast radius beyond the initially contacted server.
The fetch adapter in axios 1.7.0 through 1.17.x silently skips the maxBodyLength enforcement when a WHATWG ReadableStream body has no determinable Content-Length, allowing attacker-supplied stream data to bypass configured upload size limits. Applications that proxy or relay untrusted stream data via axios with the fetch adapter and rely solely on maxBodyLength as the size guard are exposed to uncontrolled outbound egress and potential exhaustion of upstream API quotas or bandwidth. No public exploit has been identified at time of analysis; CVSS 4.0 scores this at 6.3 with limited availability impact (VA:L) and an attack prerequisite (AT:P) reflecting the specific conditions required.
Uncontrolled recursion in axios's formDataToJSON helper (versions 0.28.0 through <0.33.0 and 1.0.0 through <1.18.0) allows unauthenticated remote attackers to exhaust the JavaScript call stack by submitting FormData with field names containing thousands of nested bracket segments. The vulnerable buildPath() function in lib/helpers/formDataToJSON.js recurses once per path segment with no depth limit, causing a RangeError that, in server-side Node.js applications lacking exception handling, can terminate the process. No active exploitation or public exploit code has been identified at time of analysis; two patched releases (0.33.0 and 1.18.0) are available.
Out-of-bounds read in Zephyr RTOS DHCPv4 client (versions 1.7.0 through 4.4.x) allows an adjacent-network attacker to crash the DHCP client or leak adjacent pointer contents by sending a crafted DHCP reply with a message-type value greater than 8. The defect is a classic sizeof-vs-ARRAY_SIZE confusion: the bounds guard compares a raw msg_type byte against the byte-size of a pointer array (32 or 64, depending on architecture) rather than its element count of 8, so values 9-31/63 bypass the check and cause a wild-pointer dereference inside a debug log call. Exploitation is gated on a non-default build configuration (CONFIG_NET_DHCPV4_LOG_LEVEL_DBG), substantially reducing the real-world attack surface. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Panic-triggered remote denial of service in pion/stun (Go STUN library) versions through 3.1.4 (v3), 2.0.0 (v2), and 1.23.1 (v1) allows an unauthenticated network attacker to crash any application embedding this library by sending a single malformed STUN or ICE Binding-response packet containing a zero-length XOR-MAPPED-ADDRESS attribute. The root cause is a misplaced bounds check in XORMappedAddress.GetFromAs that attempts to index into the value slice before validating minimum length, causing an unrecovered Go runtime panic that terminates the process. No public exploit identified at time of analysis, though the patch PR and test case publicly detail the exact malformed packet structure.
Null byte injection in the free5GC Authentication Server Function (AUSF) v4.2.1 and earlier allows unauthenticated remote attackers to crash Go's URL parser and force HTTP 500 responses on the authentication endpoint, denying authentication service to all legitimate 5G subscribers sharing that AUSF instance. A publicly available Python PoC is included in the vendor's own security advisory, and fuzzing demonstrated a 4.1% trigger rate across nearly 100,000 requests - confirming reliable, scalable exploitation against the default deployment with no special configuration required. No public exploit or CISA KEV listing is confirmed at time of analysis, but the trivially automatable nature of the attack makes it a material risk for 5G core operators.
Memory exhaustion via unbounded configuration file parsing in Pterodactyl Wings prior to v1.13.0 allows a low-privileged game server tenant to crash the Wings daemon. The parsers for JSON, YAML, XML, INI, and text configuration files in parser.go perform no size validation, enabling a malicious or oversized config file to buffer unlimited data into the Wings process heap and trigger an OOM kill. No public exploit is identified at time of analysis, and the vendor-released patch is available in v1.13.0.
Denial of service in the Advantech ECU-1251D industrial communication gateway allows a network-adjacent, high-privilege attacker to send a crafted DNP3 signal to the device's Digital Output address, forcing the DNP3Daemon into an indefinite restart loop and severing SCADA TelWin operator connectivity until a manual restart is performed. The device remains partially reachable via its web panel during the loop, which may create a false impression of operational continuity while SCADA control is lost. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog; the disclosure source is Singapore's Cyber Security Agency (CSA).
Unbounded memory consumption in Google mcp-toolbox versions through 1.4.0 allows unauthenticated remote attackers to crash the service via a single oversized HTTP request. The /mcp endpoint's toolInvokeHandler uses Go's io.ReadAll without any body-size guard - no http.MaxBytesReader, no Content-Length pre-check - so a sufficiently large POST body linearly exhausts host RAM until the OS OOM killer terminates the process. No active exploitation is confirmed (CVSS 4.0 E:U), but the attack requires no authentication and trivial complexity, making any internet-exposed deployment an easy target for denial of service.
node-re2, the Node.js native binding for Google's RE2 regular expression engine, enters an infinite loop and leaks unbounded native memory when String.prototype.match is called with a global pattern capable of producing zero-width (empty string) matches. All versions prior to 1.25.2 are affected; because RE2 executes synchronously within the Node.js event loop thread, the hang is unrecoverable without a process restart, making any service that exposes RE2 global matching to externally-supplied input susceptible to complete denial of service. No public exploit code or CISA KEV listing has been identified at time of analysis, but the trigger condition is mechanically trivial and directly exercisable from patterns confirmed in the vendor's own test additions.
Capsule's node admission webhook can be crashed cluster-wide by a Cluster Admin who stores a malformed regular expression in CapsuleConfiguration's NodeMetadata fields, causing a Go panic via regexp.MustCompile that blocks all subsequent Node create, update, and patch operations. All Capsule versions prior to 0.13.8 are affected, as confirmed by GitHub Security Advisory GHSA-68cj-mvg9-rgm2. No public exploit has been identified at time of analysis, but the Scope:Changed CVSS designation reflects that the crash cascades beyond the vulnerable Capsule component to impair node admission cluster-wide.
Denial of service in IBM Db2 federated server (versions 12.1.0 through 12.1.4) can be triggered by executing non-fenced federated queries, causing the database engine to exhaust resources and become unresponsive. The root cause is CWE-400 (Uncontrolled Resource Consumption) within the in-process federated wrapper execution path. No public exploit has been identified at time of analysis, and IBM has released a patch via their support portal.
Denial of service in Samba's Kerberos KDC password change (kpasswd) service allows authenticated remote attackers to crash the KDC process by submitting specially crafted, malformed ASN.1-encoded password change requests. The server miscalculates the structure size of the incoming request and reads up to six bytes beyond the end of the allocated buffer; when this read strikes unmapped memory, the KDC process terminates rather than simply failing gracefully. No public exploit has been identified and no CISA KEV listing exists, but the disruption of a KDC in an Active Directory or Samba domain environment carries significant operational impact since authentication for the entire domain depends on KDC availability.
Samba's internal DNS server inserts unauthenticated TKEY registration requests into the TKEY name cache before rejecting them, allowing a remote unauthenticated attacker to exhaust the cache by flooding it with arbitrary TKEY names. Eviction of legitimate cache entries blocks TSIG-authenticated DNS query processing, producing a targeted denial of service against Active Directory environments relying on Samba's built-in DNS backend. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available from both Samba upstream and Red Hat.
Regular Expression Denial of Service in Apache Superset's SQL parser (sql_parse.py) allows authenticated attackers to exhaust CPU resources on Superset worker processes by submitting crafted inputs containing pathological character sequences to SQL-processing endpoints. Versions 1.5.0 through 5.0.0 are affected via a vulnerable SQL_REGEX pattern that exhibits catastrophic backtracking under adversarial input. No public exploit code or active exploitation has been identified at time of analysis; the authentication prerequisite meaningfully limits opportunistic attack surface.
Missing brute-force protection on the DFIR-IRIS web application's authentication endpoint exposes version 2.4.26 (and potentially earlier releases) to unlimited credential-stuffing and password-spraying attacks. Unauthenticated remote attackers can submit an unbounded number of login attempts without triggering rate limiting or account lockout, making weak or reused credentials trivially recoverable. DFIR-IRIS is an incident response platform handling sensitive case data, forensic artifacts, and investigation timelines - successful account compromise gives attackers direct access to that material. No public exploit has been identified at time of analysis, and KEV status is not confirmed.
Missing rate-limiting on MFA validation in DFIR-IRIS 2.4.26 allows a remote attacker who possesses valid user credentials to systematically enumerate multi-factor authentication codes until the correct value is found, bypassing the second authentication factor and gaining unauthorized access to the DFIR investigation platform. The CVSS vector scores High confidentiality impact with no integrity or availability penalty, reflecting full read access to sensitive incident response and forensic investigation data. No public exploit code has been identified at time of analysis, and this vulnerability does not appear in the CISA KEV catalog.
Path traversal in the Performance Co-Pilot (PCP) pmproxy logger servlet on Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4 permits unauthenticated remote attackers to create arbitrary files and directories on the host filesystem by supplying a crafted hostname value in requests to the service. The primitive is write-only - no file contents can be read - but an attacker can abuse it to corrupt directory structures or exhaust disk space, leading to denial of service. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
Remote unauthenticated denial of service and memory disclosure in the Performance Co-Pilot (PCP) pmproxy service affects Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. An out-of-bounds read (CWE-125) in the pmLogLoadInDom() function can be triggered by a specially crafted network request, causing the pmproxy process to crash and potentially leaking sensitive data from process memory. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Use-after-free in Chrome's DataTransfer component on Windows exposes process memory to local attackers who can deliver a crafted HTML page to a victim. The flaw affects all Chrome versions on Windows prior to 151.0.7922.72 and results in high-confidence confidentiality loss with no integrity or availability impact. No public exploit code has been identified and EPSS sits at 0.11% (2nd percentile), consistent with CISA SSVC classifying exploitation as 'none' and technical impact as 'partial' - making this a low operational priority despite the High confidentiality CVSS sub-score.
Sandbox escape in Google Chrome's ANGLE graphics layer on Android enables an attacker who has already compromised the renderer process to break out of the Chrome sandbox via a crafted HTML page. Affected versions are all Chrome for Android releases prior to 151.0.7922.72. This is a second-stage exploit primitive requiring a prior renderer compromise; no public exploit code exists and SSVC reports exploitation as none, keeping real-world risk moderate despite the scope-change nature of the flaw.
Use-after-free in the GPU process on macOS enables sandbox escape in Google Chrome versions prior to 151.0.7922.72, but only when an attacker has already achieved renderer process compromise. This is a second-stage exploit primitive - it extends an existing renderer compromise across the sandbox boundary into the GPU process, potentially allowing arbitrary code execution outside Chrome's sandbox on macOS. No public exploit code has been identified and EPSS sits at 0.21% (11th percentile), indicating low observed exploitation probability; however, sandbox escapes are a critical capability for attackers chaining browser exploit kits.
Use-after-free in the Bluetooth component of Google Chrome on Android prior to 151.0.7922.72 enables a sandbox escape for remote attackers who have already achieved renderer process compromise. Exploitation requires delivering a crafted HTML page to a victim user and successfully triggering a memory corruption condition in the Bluetooth subsystem, allowing code execution outside the renderer sandbox. No public exploit code has been identified at time of analysis, and EPSS at 0.21% (11th percentile) indicates low observed exploitation probability; no CISA KEV listing is present.
SQLite 3.41 is vulnerable to use after free in the jsonArrayLengthFunc function.
SQLite 3.41 is vulnerable to use after free in the jsonExtractFunc function. Premature release of parsed JSON object memory leads to subsequent illegal access of freed pointer. Remote attackers can trigger this flaw via specially crafted SQL queries, resulting in service crash and sensitive memory information leakage.
Uncontrolled memory growth in the MCP Ruby SDK (mcp gem) prior to 0.23.0 allows any peer process communicating via stdio to OOM-kill the host Ruby process by sending a continuous byte stream without a newline, exhausting available system memory. Both the server-side MCP::Server::Transports::StdioTransport and client-side MCP::Client::Stdio components are affected, meaning Ruby applications acting as either MCP servers or MCP clients are vulnerable. No public exploit has been identified at time of analysis, and no CISA KEV listing exists, but the attack is mechanically trivial for any process with stdio access to the target.
Uncontrolled resource consumption in Node.js 26.x DNS module allows a network-positioned attacker to trigger a denial-of-service condition by delivering an oversized `resolveAny` DNS reply to an affected application. The vulnerability (CWE-400) was patched in Node.js v26.5.1 released 2026-07-29 as part of a broader security release addressing ten CVEs. No public exploit code and no CISA KEV listing have been identified; the CVSS AC:H metric reflects the prerequisite of controlling or spoofing DNS responses reaching the target process.
Out-of-bounds write buffer handling in the Node.js built-in zlib module (v26.x prior to v26.5.1) fails to throw an exception when a write buffer exceeds valid bounds, enabling a local denial-of-service via process crash or uncontrolled resource consumption. The Node.js security team rated this Medium severity (CVSS 6.2, AV:L) and shipped a fix in v26.5.1 on 2026-07-29 as part of a broader security release addressing ten CVEs. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Buffer overrun in the Apache Traffic Server multiplexer plugin's chunk-decode logic allows network-adjacent attackers who can influence upstream origin responses to cause denial of service across versions 8.0.0 through 10.1.3. The flaw is classified as CWE-787 (Out-of-bounds Write) and is constrained to availability impact only - no code execution or data exposure is indicated. No public exploit or CISA KEV listing has been identified, and the CVSS 3.7 Low score reflects meaningful real-world limitations, primarily the high attack complexity imposed by the upstream-input dependency.
Denial of service in IBM WebSphere Liberty 17.0.0.3 through 26.0.0.8 when the restConnector-2.0 feature is enabled, allowing authenticated remote attackers with low privileges to exhaust server resources via uncontrolled recursion (CWE-674). The attack does not require user interaction and can be conducted over the network, resulting in high availability impact and potential partial confidentiality disclosure. No public exploit or active exploitation has been confirmed at time of analysis.
Use-after-free in the sqlite3 Ruby gem (published as both sqlite3-ruby and sqlite3) versions 2.1.0 through 2.9.4 lets an aggregate function be invoked through a still-open prepared statement after its Database object has been explicitly closed, producing an invalid memory read and a segmentation fault that crashes the Ruby process. Exploitation requires an in-process API-misuse pattern in the host application itself - local, high-complexity, low-privileged per the assessed CVSS:3.1 vector (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L) - with no remote or network vector and no attacker-supplied input. No public exploit identified at time of analysis (EPSS 0.11%, CISA SSVC exploitation: none, Automatable: no); the maintainers classify it as Low severity, describing a reliably reproducible crash after garbage collection rather than a proven denial-of-service or code-execution primitive.
Improper input validation in the BlackBerry UEM Management Console (versions 12.23.0 QF8 and earlier, and 12.22.1 QF7 and earlier) enables unauthenticated remote attackers to trigger arbitrary file download operations and a potential denial of service condition against the console when a Management Console user interacts with attacker-influenced content. The CVSS 4.0 vector reflects high availability impact on the vulnerable system (VA:H) with residual integrity and availability effects on subsequently managed systems (SI:L/SA:L), though the vendor rates confidentiality impact as none (VC:N) - a notable discrepancy given the 'Arbitrary File Download' language in the description that warrants vendor clarification. No public exploit code or active exploitation has been identified; EPSS places this at the 11th percentile (0.21%) and SSVC independently assesses exploitation as none with a non-automatable attack path.
A use-after-free vulnerability in the sqlite3-ruby gem allows an attacker to crash the Ruby process by defining a custom SQLite function with the same name but a different number of arguments or text encoding, leading to an invalid memory read and segmentation fault. The issue affects versions prior to 2.9.5 and was assessed as low severity by the maintainers due to the specific code pattern required for exploitation.
Remote unauthenticated denial of service in gopacket <= 1.6.0 via a single crafted sFlow UDP datagram that triggers an unbounded memory allocation of up to 16 GiB, causing the parsing process to be OOM-killed. Affected services include any network telemetry collector or application that uses gopacket’s sFlow decoder without additional validation. A proof-of-concept exploit exists and can crash the process with just a 104-byte packet.
Remote denial-of-service in the gopacket library's Diameter AVP decoder allows unauthenticated attackers to trigger a ~4 GiB memory allocation per crafted packet, causing OOM kill after two messages under memory constraints. The flaw affects gopacket ≤1.6.0 (latest before fix), and publicly available exploit code demonstrates end-to-end exploitation against a collector with a 256 MB memory cap. No active exploitation is currently reported.
Uncontrolled resource consumption in Apache Tomcat's default WebSocket chat example allows remote attackers to cause denial of service. Affected versions include 11.0.0-M20 through 11.0.24, 10.1.24 through 10.1.57, and 9.0.89 through 9.0.120; users who have removed the examples web application as recommended are not impacted. No public exploit code or active exploitation is reported.
Processing specially crafted graph data in Pivotick can lead to unreliable visualizations, corrupted cycle detection, and client-side denial-of-service. An attacker can craft node identifiers that collide with Object.prototype properties ('constructor', 'toString', '__proto__'), causing prototype pollution and logic errors. No known active exploitation or public exploit code exists, but the vulnerability is trivially triggered by user interaction.
Unauthenticated disabling of the ACME service in Dogtag PKI allows persistent denial of service via URL manipulation. By appending a trailing slash to admin-only enable/disable endpoints, an attacker can bypass the Tomcat authentication constraint while RESTEasy routes the request, enabling unauthorized toggling. No public exploit or active exploitation has been reported.
Memory exhaustion in Lookyloo 1.40.0 and earlier allows attackers to crash web or worker processes by submitting a crafted ZIP capture archive or gzip-compressed HAR payload that expands to an enormous size when decompressed in memory, degrading or taking the instance offline until processes are restarted. Both the full capture-archive import path and the API submission path that accepts gzip-compressed HAR data are affected, and although authentication requirements are not confirmed for every entry point, the published CVSS:4.0 vector records PR:N for the API path. The vulnerability is vendor-patched via upstream commit 96589da (a 1 GB uncompressed ceiling plus size-bounded zlib/gzip decompression), there is no CISA KEV listing, no public exploit code identified at time of analysis, and the EPSS score is a low 0.25% (17th percentile); this is a genuine but modest-priority denial-of-service issue rather than a high-urgency threat.
Resource exhaustion in Ninenines Cowboy's HTTP/1.1 handler allows unauthenticated remote attackers to cause denial of service by sending many header lines with the same name, bypassing the max_headers limit due to counting distinct names instead of total lines. Affects Cowboy versions 2.0.0-pre.4 to 2.17.x; fixed in 2.18.0. No public exploit or active exploitation has been reported at this time.
Safari and WebKit-based apps across Apple platforms crash when a user visits a specially crafted website, due to a state management flaw (CWE-400: Uncontrolled Resource Consumption) in versions prior to 26.6. Affected platforms include Safari on macOS Tahoe, iOS 26, iPadOS 26, and visionOS 26. No confidentiality or integrity impact is present - the consequence is an app-level denial-of-service. No public exploit code exists and CISA SSVC confirms no active exploitation, with EPSS at 0.16% (6th percentile), indicating very low exploitation likelihood at time of analysis.
Denial of service in macOS versions prior to Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6 allows a local malicious app to trigger memory corruption and crash the system.

No public exploit or active exploitation has been identified at this time, and the EPSS score is low (0.17%).
Unexpected Safari crash via use-after-free when processing maliciously crafted web content affects Safari 26.6 and earlier on all Apple platforms. This denial-of-service condition requires user interaction to open a malicious webpage; no public exploit identified and EPSS probability is low (0.14%).
Denial of service in macOS Tahoe fixed by removing vulnerable code. A local attacker with low privileges can cause a denial-of-service condition. No active exploitation or public exploit known, and the low EPSS score (0.14%) indicates limited real-world risk.
An integer overflow in GIMP's file-sgi plugin, triggered by a crafted RLE-compressed SGI image, causes denial of service by crashing the plugin. The vulnerability affects GIMP versions with the file-sgi plugin and requires a user to open a malicious image file. No public exploit or active exploitation is known at this time; the issue is being tracked by GNOME and Red Hat.
Denial of service in Zephyr's Synopsys DesignWare I2C driver (slave mode) enables an I2C master on the same physical bus to cause permanent failure of the write_requested() callback due to a missing START_DET interrupt enable. This halts all subsequent write transactions and desynchronizes higher-layer framing until device reset. No public exploit identified; patch available from vendor.
Denial of service in HDF5 caused by a NULL pointer dereference when processing a crafted HDF5 file with an invalid variable-length datatype attribute. The vulnerability affects all versions of HDF5 and can be triggered by a user opening a malicious file, leading to application crash. Publicly available exploit code exists per CVSS metric.
Heap-based buffer overflow in HDF5 through 2.1.1 enables attackers to crash applications and potentially corrupt data by providing a crafted HDF5 file. The flaw lies in the shared‑message list‑index deserializer (SOHM), allowing out‑of‑bounds heap reads and writes when a num_messages field exceeds the declared list_max. No active exploitation has been reported, but the issue is publicly documented and a proof‑of‑concept may exist in the linked issue.
Denial of service vulnerability in Mattermost allows authenticated users to exhaust server resources by uploading crafted animated GIFs as custom emoji. Affects versions 10.11.x, 11.6.x, 11.7.x, and 11.8.x up to certain patch levels. No active exploitation or public exploit is known, but patches are available from the vendor.
Denial of service in Mattermost 10.11.x through 11.8.x allows authenticated users with file-upload permission to degrade file-upload performance for all users by exploiting unbounded resource consumption during server-side document extraction. Attackers can repeatedly upload small documents that are expensive to extract, saturating the extraction worker pool and causing service degradation. No active exploitation or public exploit code is reported, but the low attack complexity and minimal privileges make this an accessible DoS vector.
Out-of-bounds heap read in GNU Binutils linker when processing 32-bit XCOFF files allows local attackers to disclose heap memory and cause denial of service. Affects Red Hat Enterprise Linux 6 through 10, Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation identified at time of analysis; EPSS data unavailable.
Local denial of service in ggml-org whisper.cpp 95ea8f9b via reachable assertion in ggml_ftype_to_ggml_type function. A local attacker with low privileges can cause a crash by supplying an invalid ftype argument. No public exploit identified; no patch available as vendor has not responded to issue report.
Denial-of-service in the Mercusys MB115-4G router's web interface allows unauthenticated attackers to crash the administration service by sending a crafted request to the /cgi/login endpoint. A stack buffer overflow in the http_gdpr_decrypt function corrupts memory and halts the httpd process, leaving the device operational but unmanageable through the web UI. A vendor patch is available; no public exploit or active exploitation has been identified.
Integer overflow in the print_string_ptr() function of the cJSON library on 32-bit platforms causes a heap buffer overflow when processing crafted JSON strings with approximately 858,993,460 control characters. Applications using cJSON_PrintBuffered() with a pre-allocated buffer are vulnerable, potentially leading to remote code execution, information disclosure, or denial of service. No public exploit or active exploitation has been identified at the time of analysis.
Remote denial of service in llama.cpp allows unauthenticated attackers to exhaust server resources via crafted JSON schema inputs that trigger unbounded recursion in the JSON-schema-to-GBNF conversion routine. Affected versions include commit e15efe0 and prior. A fix exists in a pending pull request; no active exploitation reported.
Denial of service in ggml-org llama.cpp allows remote attackers to crash the application by sending a crafted JSON schema that triggers a null pointer dereference in the _visit_pattern function. No authentication or user interaction is required, and all versions up to the affected commits d006858/e15efe0 are vulnerable. The fix is pending merge; no public exploit code has been identified.
