Memory exhaustion in libp2p-rendezvous allows unauthenticated attackers to cause denial-of-service via unbounded pagination cookie storage. Remote attackers can repeatedly send protocol-compliant DISCOVER requests to force unlimited HashMap growth without authentication or rate limiting. No public exploit identified at time of analysis, though proof-of-concept exists in maintainer-controlled fork. EPSS data not available for this newly-assigned CVE; CVSS 8.2 reflects high availability impact with low attack complexity.

Unbounded namespace registration in libp2p-rendezvous allows remote unauthenticated attackers to trigger out-of-memory conditions on rendezvous servers. The Rust implementation accepts unlimited unique namespace registrations per peer with 72-hour TTLs, enabling resource exhaustion via repeated REGISTER messages. Confirmed publicly available exploit code exists. CVSS 7.5 (High) reflects network accessibility and lack of authentication barriers, while the straightforward attack vector (simple loop of registration requests) presents immediate risk to public rendezvous nodes critical for peer discovery in libp2p networks.

Directus GraphQL endpoints fail to deduplicate resolver invocations within single requests, allowing authenticated users to exploit GraphQL aliasing for denial-of-service attacks. An attacker with minimal read-only permissions can repeat expensive relational queries using multiple aliases in a single request, forcing concurrent execution of numerous complex database queries that exhaust connection pools and server resources, potentially degrading or crashing the service. No public exploit code has been identified, and this vulnerability requires prior authentication to the Directus instance.

Regular Expression Denial of Service (ReDoS) in @hapi/content npm package versions through 6.0.0 allows unauthenticated remote attackers to crash Node.js processes via a single HTTP request containing maliciously crafted Content-Type or Content-Disposition header values. Three regular expressions used for header parsing contain catastrophic backtracking patterns that can consume unbounded CPU resources. Vendor-released patch available via GitHub (PR #38). No public exploit code identified at time of analysis, though the attack vector is straightforward for any attacker with HTTP request capabilities.

Denial of service in Avahi prior to version 0.9-rc4 allows local unprivileged users to crash avahi-daemon by sending a D-Bus method call with conflicting publish flags. The vulnerability requires local access and low privileges but causes immediate service unavailability. No public exploit code or active exploitation has been confirmed; however, the attack is trivial to execute given the low complexity barrier.

Thread exhaustion in Mesop WebSocket handler (pkg:pip/mesop) allows unauthenticated remote attackers to crash applications via message flooding. The framework spawns unbounded OS threads for each received WebSocket message without rate limiting or pooling, enabling complete denial of service with minimal bandwidth. CVSS 7.5 (High). Publicly available exploit code exists. EPSS data not provided, but the low attack complexity (AC:L) and zero authentication requirement (PR:N) combined with working proof-of-concept significantly elevate real-world exploitation risk. Vendor-released patch available in version 1.2.5 (commit 760a207).

Denial of service in vLLM's VideoMediaIO.load_base64() method allows authenticated remote attackers to crash the server via memory exhaustion by sending API requests with thousands of comma-separated base64-encoded JPEG frames. The vulnerability bypasses the default 32-frame limit enforced in other video loading code paths, allowing attackers to decode gigabytes of image data into memory (e.g., 5000 frames ≈ 4.6 GB for 640x480 RGB) with a small compressed payload. CVSS 6.5 (network-accessible, low complexity, requires authentication, high availability impact); no public exploit code identified at time of analysis.

Denial of service in @nyariv/sandboxjs through unbounded recursion in the parser allows remote attackers to crash Node.js processes by submitting deeply nested expressions (approximately 2000 nested parentheses or brackets), triggering a RangeError that terminates the application. All public API methods (Sandbox.parse, Sandbox.compile, Sandbox.compileAsync, Sandbox.compileExpression, Sandbox.compileExpressionAsync) are vulnerable with no input validation or depth limiting. A proof-of-concept demonstrating the crash exists; no public active exploitation has been reported at the time of analysis.

Memory exhaustion denial of service in jupyterhub-litauthenticator 1.6.2 and earlier allows unauthenticated remote attackers to crash the LTI 1.1 validator by submitting repeated requests with unique OAuth nonces. The vulnerability exists because nonces are stored in an unbounded class-level dictionary before signature validation occurs, enabling an attacker with knowledge of a valid consumer key to gradually exhaust server memory without authentication. EPSS score of 5.9 (medium-high) reflects the network attack vector and practical exploitability, though the requirement to know a valid consumer key and achieve high authentication complexity moderates real-world risk.

Hirschmann HiSecOS devices versions prior to 05.3.03 contain a buffer overflow vulnerability in the HTTPS login interface when RADIUS authentication is enabled that allows remote attackers to crash. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Resource exhaustion in Amazon Athena ODBC driver versions prior to 2.1.0.0 allows unauthenticated remote attackers to trigger denial of service through maliciously crafted input that overwhelms parsing logic. CVSS 7.5 (High) reflects network-accessible attack vector with low complexity and no prerequisites. EPSS data not provided, but no public exploit or CISA KEV listing identified at time of analysis. Amazon has released patches for Windows, Linux, and macOS platforms.

Denial of service in rust-rpm-sequoia allows local attackers to crash RPM signature verification by submitting specially crafted RPM files that trigger unhandled errors in OpenPGP parsing, preventing legitimate package management operations. CVSS 4.0 (low severity), local attack vector, non-authenticating. No public exploit code or active exploitation confirmed.

MLflow's FastAPI job endpoints bypass basic-auth entirely, allowing network attackers to submit and execute jobs without credentials (CVSS 9.8, CWE-306). Affects mlflow/mlflow latest version when MLFLOW_SERVER_ENABLE_JOB_EXECUTION=true and job functions are allowlisted. Public POC exists per SSVC framework. EPSS score of 0.20% (42nd percentile) indicates low observed exploitation probability despite critical CVSS, suggesting targeted rather than widespread risk. Vendor-released patch not confirmed at time of analysis - remediation relies on configuration changes and service hardening.

Denial of Service in vLLM OpenAI-compatible API server allows unauthenticated remote attackers to crash the service via a single HTTP request containing an extremely large n parameter. The lack of upper bound validation causes the asyncio event loop to freeze while allocating millions of request object copies, leading to rapid Out-Of-Memory crashes. CVSS 6.5 with moderate real-world risk due to authentication requirement in the disclosed CVSS vector (PR:L), though the description indicates unauthenticated exploitability - a significant discrepancy warranting clarification from the vendor.

Email flooding denial of service in Budibase prior to version 3.23.25 allows unauthenticated remote attackers to overwhelm user inboxes by repeatedly triggering password reset requests without rate limiting, CAPTCHA, or abuse prevention controls. An attacker can send hundreds of password reset emails to a target address in a short time window, causing user harassment, inbox denial of service, and potential reputational damage. This vulnerability has been patched in version 3.23.25.

NULL pointer dereference in Linux kernel NFSD export cache cleanup allows local denial of service when RCU readers in e_show() and c_show() concurrently access export path and client name objects while cache_clean removes entries and drops the last reference prematurely. The vulnerability stems from path_put() and auth_domain_put() executing before the RCU grace period completes, freeing sub-objects still in use by readers. A fix has been merged upstream that defers these cleanup operations to a dedicated workqueue after the RCU grace period, ensuring safe resource release in process context where sleeping is permitted.

Use-after-free in the Linux kernel's nvdimm/bus subsystem allows local privileged users to potentially trigger memory corruption when device_add() fails during nd_async_device_register() asynchronous initialization. The flaw stems from the parent device reference being dropped before the parent pointer is accessed on allocation failure paths. No public exploit identified at time of analysis, and EPSS exploitation probability is very low at 0.02%.

Linux kernel mm/rmap subsystem fails to correctly preserve page table entry attributes (writable and soft-dirty bits) when batching unmap operations on lazyfree folios, causing kernel panic via page table check violation when a large folio with mixed writable/non-writable PTEs is unmapped across multiple processes. The vulnerability affects all Linux kernel versions with the vulnerable folio_unmap_pte_batch() code path and can be triggered by local attackers through a specific sequence of memory management syscalls (MADV_DONTFORK, fork(), MADV_DOFORK, MADV_FREE, and memory reclaim), resulting in denial of service via kernel crash.

Linux kernel memory management allows installation of PMD entries pointing to non-existent physical memory or causes NULL pointer dereferences in move_pages_huge_pmd() when handling huge zero page migrations via UFFDIO_MOVE. The vulnerability occurs because the function incorrectly handles NULL folio pointers for huge zero pages, either producing bogus page frame numbers on SPARSEMEM_VMEMMAP systems or dereferencing NULL on other memory models. Additionally, destination PMD entries lose special mapping metadata (pmd_special flag), causing subsequent page reference counting corruption. No CVSS score is available; no active exploitation reported.

Null pointer dereference in Linux kernel mac80211 IEEE 802.11 wireless subsystem crashes AP_VLAN stations during channel bandwidth change operations. The ieee80211_chan_bw_change() function incorrectly accesses link data on VLAN interfaces (such as 4-address WDS clients) where the link structure is uninitialized, leading to kernel panic when dereferencing a NULL channel pointer. Any system with AP_VLAN wireless configurations and active channel state announcement (CSA) operations is vulnerable to local denial of service.

NULL-pointer dereference in Linux kernel SPI subsystem allows local denial of service via sysfs attribute access. The SPI controller's per-CPU statistics structure is not allocated until after the controller registers with the driver core, creating a race window where sysfs attribute reads can trigger a kernel panic. This affects all Linux kernel versions with the vulnerable SPI statistics implementation; exploitation requires local system access to read sysfs files.

Linux kernel io_uring/poll multishot recv can hang indefinitely when a socket shutdown occurs concurrently with data reception, due to a race condition where accumulated poll wakeups are drained without consuming the persistent HUP event. The vulnerability affects all Linux kernel versions with io_uring poll support and requires a fix to explicitly check for HUP conditions and re-loop when multiple poll activations are pending.

Infinite loop in Linux kernel serial core driver handle_tx() affects systems using uninitialized PORT_UNKNOWN serial ports, where uart_write_room() and uart_write() behave inconsistently regarding null transmit buffers, causing denial of service through system hangs. The vulnerability impacts caif_serial and other drivers that rely on tty_write_room() to determine write capacity. Patch available in upstream kernel commits; no CVSS score assigned due to kernel-specific nature and relatively limited exposure scope.

Linux kernel drm/imagination driver crashes when the GPU runtime PM suspend callback executes concurrently with an IRQ handler attempting to access GPU registers, causing kernel panics with SError interrupts on ARM64 platforms. The vulnerability affects the imagination GPU driver across Linux kernel versions and is triggered when power management suspend operations race with interrupt handling without proper synchronization. The fix adds synchronize_irq() calls to ensure IRQ handlers complete before GPU suspension and removes problematic runtime PM resume calls from the IRQ handler that could cause deadlocks.

Denial of service in Linux kernel amdgpu driver allows local attackers to exhaust system memory by passing an arbitrarily large BO (buffer object) list entry count via userspace, bypassing existing overflow checks but causing excessive allocation and processing delays; fixed by enforcing a 128k entry limit per BO list.

NULL pointer dereference in Linux kernel DRM i915 GPU driver allows local denial of service during system probe when DMC firmware initialization has not yet completed but hardware has DC6 power state enabled. The vulnerability occurs in intel_dmc_update_dc6_allowed_count() when called from gen9_set_dc_state() during intel_power_domains_init_hw(), which executes before DMC initialization, causing kernel oops if DC6 is unexpectedly enabled by BIOS firmware. No public exploit code identified; this is a kernel crash vulnerability requiring local system access triggered by atypical BIOS behavior.

NULL pointer dereference in Linux kernel ROSE socket implementation allows local denial of service when rose_connect() is called twice during an active connection attempt. The vulnerability occurs because rose_connect() fails to validate TCP_SYN_SENT state, permitting rose->neighbour to be overwritten with NULL, which later causes a kernel crash when rose_transmit_link() dereferences the NULL pointer during socket closure. No active exploitation reported; fix available in upstream kernel commits.

Use-after-free in Linux kernel MANA hardware channel teardown (net/mana driver) allows concurrent interrupt handlers to dereference freed memory in mana_hwc_destroy_channel(), potentially causing NULL pointer dereference or memory corruption. The vulnerability stems from improper teardown ordering where hwc->caller_ctx is freed before CQ/EQ IRQ handlers are fully synchronized, affecting all Linux kernel versions with the MANA driver. Fixes are available across stable kernel branches via upstream commit reordering.

Infinite loop in Linux kernel bonding device header parsing allows local denial of service when two bonding devices are stacked. The bond_header_parse() function can recurse indefinitely because skb->dev always points to the top of the device hierarchy. The fix adds a bounded recursion parameter to the header_ops parse() method to ensure the leaf parse method is called and prevent endless loops. This vulnerability affects all Linux kernel versions with the vulnerable bonding code and requires local access to trigger.

NULL dereference and use-after-free in the Linux kernel's SMC (Shared Memory Communications) socket implementation occur when smc_tcp_syn_recv_sock() races with socket close operations, allowing a local attacker to trigger a kernel panic via concurrent manipulation of TCP SYN handling and SMC listen socket closure. The vulnerability affects the Linux kernel across multiple versions via the net/smc subsystem and is addressed through RCU-protected access and refcount validation rather than lock-based serialization.

Double-free memory corruption in the Linux kernel's TEQL (Trivial Link Equalizer) qdisc implementation allows local attackers to cause kernel crashes via denial of service. The vulnerability occurs when qdisc_reset is called without proper synchronization on lockless Qdisc root configurations, creating a race condition that results in use-after-free and double-free conditions in packet buffer management. This affects all Linux kernel versions with the vulnerable TEQL code path and requires local access to trigger via specially crafted packet scheduling operations.

Use-after-free vulnerability in Linux kernel ACPI processor errata handling allows local attackers to cause denial of service or potentially execute code via device pointer dereference after reference dropping in acpi_processor_errata_piix4(). The vulnerability affects multiple Linux kernel versions and was introduced in a previous fix attempt (commit f132e089fe89); it has been resolved across stable kernel branches with no active public exploitation identified.

NULL pointer dereference in Linux kernel IPv6 SRv6 path processing allows local denial of service when __in6_dev_get() returns NULL due to missing IPv6 configuration or device unregistration. The vulnerability affects seg6_hmac_validate_skb() and ipv6_srh_rcv() functions which lacked NULL checks on the returned idev pointer, enabling a local attacker to crash the kernel by triggering these code paths on misconfigured or unregistering network devices.

Linux kernel NULL pointer dereference in UDP tunnel socket creation when IPv6 is disabled causes denial of service. When CONFIG_IPV6=n, the udp_sock_create6() function incorrectly returns success (0) without creating a socket, leading callers such as fou_create() to dereference an uninitialized pointer. The vulnerability is triggered via netlink socket operations and requires privileged user access; no public exploit code or active exploitation has been identified at time of analysis.

Denial of service in Linux kernel mvpp2 network driver occurs when MTU changes or other operations trigger buffer pool switching on Marvell hardware lacking CM3 SRAM support, causing NULL pointer dereference in flow control register access. Affects systems running vulnerable kernel versions on Marvell Armada platforms where the CM3 SRAM device tree entry is absent; no authentication required. Upstream fix available via stable kernel commits.

Linux kernel NULL pointer dereference in the x86 PMU NMI handler on AMD EPYC systems causes denial of service when perf event unthrottling races with PMU rescheduling. The vulnerability stems from commit 7e772a93eb61 moving event pointer initialization later in x86_pmu_enable(), allowing the unthrottle path to set active_mask bits without populating the corresponding events[] array entries, leading to NULL pointer dereference when subsequent PMC overflow interrupts fire. No public exploit code identified at time of analysis; patch fixes are available in upstream Linux kernel stable branches.

Null pointer dereference in Linux kernel arm_mpam memory bandwidth monitoring causes kernel oops when an MSC supporting bandwidth monitoring transitions offline and back online. The mpam_restore_mbwu_state() function fails to initialize a value buffer before passing it to __ris_msmon_read() via IPI, triggering a crash in the bandwidth counter restoration routine. This affects ARM systems with MPAM (Memory Partitioning and Monitoring) support and results in denial of service through system instability when memory controllers are toggled.

Linux kernel crashes in iommu_sva_unbind_device() when accessing a freed mm structure after iommu_domain_free() deallocates domain->mm->iommu_mm, causing denial of service on systems using IOMMU Shared Virtual Addressing (SVA). The fix reorders code to access the structure before the domain is freed. No CVSS score, EPSS, or KEV status available; no public exploit code identified.

Denial of service in MariaDB Server through large packet crashes when the caching_sha2_password authentication plugin is enabled and accounts use it, due to unbounded stack allocation in sha256_crypt_r. Authenticated remote attackers can crash the server by sending a crafted large authentication packet. MariaDB versions before 11.4.10, 11.5.0 through 11.8.5, and 12.0.0 through 12.2.1 are affected. No public exploit code or confirmed active exploitation reported at time of analysis.

Unauthenticated server-side request forgery in Ech0's link preview endpoint allows remote attackers to force the application server to perform HTTP/HTTPS requests to arbitrary internal and external targets. The /api/website/title route requires no authentication, performs no URL validation, follows redirects by default, and disables TLS certificate verification (InsecureSkipVerify: true). Attackers can probe internal networks, access cloud metadata services (169.254.169.254), and trigger denial-

Denial of service via panic in go-jose library (versions prior to v4.1.4 and v3.0.5) occurs when decrypting malformed JSON Web Encryption (JWE) objects that specify a key wrapping algorithm (e.g., RSA-OAEP-KW, ECDH-ES+A128KW) but contain an empty encrypted_key field. The panic is triggered during slice allocation in cipher.KeyUnwrap() when processing ciphertext under 16 bytes, causing immediate application termination. No public exploit identified at time of analysis, though EPSS score of 0.0004

Denial of service in Dokuwiki version 2025-05-14b 'Librarian' release allows remote attackers to crash or disable the application through improper input handling in the media_upload_xhr() function within media.php. The vulnerability requires network access to the media upload endpoint but does not require authentication. No public exploit code, CVSS scoring, or active exploitation has been confirmed at the time of analysis.

Hirschmann EagleSDV contains a denial-of-service vulnerability that causes the device to crash during session establishment when using TLS 1.0 or TLS 1.1. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Uncontrolled Resource Consumption vulnerability could allow attackers to cause denial of service by exhausting system resources.

Unbounded disk consumption in Rack's multipart parser allows remote denial of service when HTTP requests lack Content-Length headers. Rack versions prior to 2.2.23, 3.1.21, and 3.2.6 fail to enforce size limits on multipart/form-data uploads sent via chunked transfer encoding, enabling unauthenticated attackers to exhaust disk space by streaming arbitrarily large file uploads. CVSS 7.5 (High) reflects the network-accessible, low-complexity attack requiring no privileges. No public exploit identified at time of analysis, though the attack technique is well-understood.

Denial of service in Rack versions prior to 2.2.23, 3.1.21, and 3.2.6 allows unauthenticated remote attackers to consume disproportionate CPU, memory, I/O, and bandwidth by supplying many small overlapping byte ranges in HTTP Range headers, bypassing the existing CVE-2024-26141 fix that only validates total byte coverage. The vulnerability affects Rack's file-serving paths that process multipart byte range responses, enabling attackers to degrade service availability with minimal request complexity.

Denial of service in Rack::Utils.select_best_encoding allows unauthenticated remote attackers to consume disproportionate CPU resources via a crafted Accept-Encoding header containing multiple wildcard entries, affecting Rack versions prior to 2.2.23, 3.1.21, and 3.2.6. The vulnerability exploits quadratic time complexity in the encoding selection algorithm used by Rack::Deflater middleware, enabling a single HTTP request to trigger sustained CPU exhaustion and application unavailability.

Denial of service via algorithmic complexity in Rack multipart parser allows unauthenticated remote attackers to exhaust CPU resources by sending specially crafted multipart/form-data requests with backslash-heavy escaped parameter values. Affects Rack 3.0.0.beta1-3.1.20 and 3.2.0-3.2.5, a critical Ruby web server interface used across Rails and Sinatra applications. CVSS 7.5 (High) with network-accessible attack vector and low complexity. Vendor-released patches available in versions 3.1.21 and 3.2.6. No public exploit identified at time of analysis, though EPSS data not provided to assess probability of exploitation.

Denial of service in Apache Traffic Server 9.0.0-9.2.12 and 10.0.0-10.1.1 caused by improper handling of POST requests that triggers a server crash under specific conditions. The vulnerability affects all instances of the affected versions and requires no authentication or special privileges to exploit. Vendor-released patches are available in versions 9.2.13 and 10.1.2.

Memory exhaustion in Suricata network IDS/IPS via HTTP/2 CONTINUATION frame flooding allows remote unauthenticated attackers to trigger denial of service, typically forcing operating system termination of the Suricata process. Affects all versions prior to 7.0.15 and 8.0.4. EPSS data not available, but CVSS 7.5 (High) reflects network-accessible attack with low complexity requiring no privileges. No public exploit identified at time of analysis, though the attack technique (HTTP/2 frame flooding) is well-documented in protocol security research.

NULL pointer dereference in Suricata 8.0.0 through 8.0.3 causes denial of service when processing malformed TLS traffic with the 'tls.alpn' rule keyword. Remote unauthenticated attackers can crash the IDS/IPS engine by sending specially crafted network packets, completely disabling network security monitoring. EPSS data not available, but the low attack complexity (AC:L) and network vector (AV:N) combined with high availability impact (A:H) indicate significant operational risk for organizations relying on Suricata for traffic inspection. No evidence of active exploitation (no CISA KEV listing) or public exploit code identified at time of analysis.

CocoaMQTT library versions prior to 2.2.2 allow remote denial of service when parsing malformed MQTT packets from a broker, causing immediate application crashes on iOS, macOS, and tvOS devices. An attacker or compromised MQTT broker can publish a 4-byte malformed payload with the RETAIN flag to persist it indefinitely, ensuring every vulnerable client that subscribes receives the crash-inducing packet, effectively bricking the application until manual intervention on the broker. The vulnerability requires an authenticated user context (PR:L in CVSS vector) but impacts application availability with high severity; patch version 2.2.2 is available.

Denial of Service in Red Hat Build of Keycloak allows unauthenticated remote attackers to exhaust server resources by submitting specially crafted POST requests with excessively long scope parameters to the OpenID Connect token endpoint. No public exploit identified at time of analysis, but CVSS 7.5 (High) with network attack vector and low complexity indicates straightforward exploitation. Authentication requirements: unauthenticated (CVSS PR:N). The vulnerability stems from improper resource management (CWE-1050), enabling attackers to cause prolonged processing times and service disruption without any authentication or user interaction.

Denial of service in gleam-wisp wisp 0.2.0 through 2.2.1 allows unauthenticated remote attackers to exhaust server memory or disk by sending arbitrarily large multipart form submissions that bypass configured size limits. The multipart_body and multipart_headers parsing functions fail to properly decrement resource quotas for chunks lacking multipart boundaries, enabling attackers to accumulate unbounded data in a single HTTP request. Patch available as of version 2.2.2.

Resource exhaustion in Nothings stb library versions up to 1.22 allows unauthenticated remote attackers to cause denial of service through the setup_free function in stb_vorbis.c when processing malformed audio data. The vulnerability has publicly available exploit code and a low CVSS score of 4.3 reflecting limited impact, but represents a real availability risk in applications embedding this widely-used header-only graphics and audio library.

Denial of service in PraisonAI's MCPToolIndex.search_tools() allows authenticated remote attackers to block the Python thread for hundreds of seconds via a crafted regular expression causing catastrophic backtracking. The vulnerable function compiles caller-supplied query strings directly as regex patterns without validation, timeout, or exception handling. A single malicious request can sustain complete service outage, and the MCP server HTTP transport runs without authentication by default, significantly lowering the practical barrier to exploitation despite the CVSS requiring PR:L.

IBM Aspera Shares 1.9.9 through 1.11.0 lacks proper rate limiting on authenticated user email submissions, allowing high-privilege users to trigger email flooding or denial of service conditions. The vulnerability requires authentication at the admin or high-privilege level and results in service availability degradation rather than data compromise. EPSS exploitation probability is low (2.7 CVSS, high privilege requirement), and no public exploit code or active exploitation has been identified at time of analysis.

Ella Core panics and crashes when processing malformed NGAP handover failure messages from a gNodeB, causing a denial of service for all connected mobile subscribers. An authenticated attacker with high privileges on the radio network can force a gNodeB to send crafted NGAP handover failure messages that trigger a null pointer dereference in Ella Core's handover handler, terminating the core network process. No public exploit code or active exploitation has been identified.

Haraka email server crashes when processing emails with `__proto__` as a header name, enabling remote unauthenticated denial of service. Attackers can send a specially crafted email via SMTP to crash worker processes, disrupting email delivery. In single-process deployments, the entire server becomes unavailable; in cluster mode, all active sessions are terminated. No public exploit identified at time of analysis beyond the published proof-of-concept code, though exploitation requires only basic SMTP access.

Denial of service vulnerability in Nothings stb image library (stb_image.h) affecting GIF decoder function stbi__gif_load_next allows remote attackers to trigger application crashes through specially crafted GIF files. The vulnerability impacts stb versions up to 2.30, requires user interaction to open a malicious GIF, and has publicly available exploit code with no vendor patch available despite early disclosure.

The vulnerability affects all versions before 3.13.4 and carries a low CVSS score (2.7) reflecting limited availability impact, with no public exploit code or active exploitation confirmed at time of analysis.

Memory exhaustion vulnerability in AIOHTTP prior to version 3.13.4 allows unauthenticated remote attackers to trigger denial of service via specially crafted HTTP responses containing excessive multipart headers. The vulnerability exploits insufficient memory limits during multipart header parsing, causing the server or client to consume more memory than intended. CVSS 6.6 (medium-high availability impact) with no public exploit code identified at time of analysis.

Unbounded DNS cache in AIOHTTP prior to version 3.13.4 allows remote attackers to cause denial of service through excessive memory consumption. An attacker can trigger repeated DNS lookups with unique hostnames to grow the in-memory cache without bounds, eventually exhausting available system memory. AIOHTTP 3.13.4 and later include a patch that implements cache limits. This is a network-accessible vulnerability requiring no authentication or user interaction, but exploitation requires deliberate attack traffic and does not result in data compromise or system takeover.

Remote code execution in OpenSTAManager v2.10.1 and earlier allows authenticated attackers to achieve unauthenticated RCE via chained exploitation of arbitrary SQL injection (GHSA-2fr7-cc4f-wh98) and insecure PHP deserialization in the oauth2.php endpoint. The unauthenticated oauth2.php file calls unserialize() on attacker-controlled database content without class restrictions, enabling gadget chain exploitation (Laravel/RCE22) to execute arbitrary system commands as www-data. Attack requires in

Time-based blind SQL injection in OpenSTAManager ≤2.10.1 allows authenticated users to extract complete database contents including credentials, financial records, and PII through multiple AJAX select handlers. The vulnerability affects three core modules (preventivi, ordini, contratti) where the `options[stato]` GET parameter is concatenated directly into SQL WHERE clauses without validation. Exploitation requires only low-privilege authentication (CVSS PR:L) and has been confirmed with working

Memory exhaustion in aiohttp's header and trailer handling allows remote attackers to cause denial of service by sending attacker-controlled HTTP requests or responses with uncapped header/trailer values. The vulnerability affects aiohttp Python library across affected versions, enabling attackers to exhaust application memory without authentication. A mitigation is available via reverse proxy configuration, and upstream patch has been released.

Remote denial of service via integer overflow in Corosync cluster engine affects Red Hat Enterprise Linux 7-10 and OpenShift Container Platform 4. Unauthenticated attackers can send crafted UDP packets to crash Corosync services running in totemudp/totemudpu mode (CVSS 7.5, AV:N/PR:N). EPSS data not provided; no public exploit identified at time of analysis. Impacts high-availability cluster deployments where Corosync provides quorum and messaging services.

Out-of-bounds read in Corosync allows unauthenticated remote attackers to crash cluster nodes and potentially leak memory via malformed UDP packets. Affects default totemudp/totemudpu configurations across Red Hat Enterprise Linux 7/8/9/10 and OpenShift Container Platform 4. CVSS 8.2 (High) with network attack vector, low complexity, and no authentication required. EPSS and exploitation status data not available; no public exploit identified at time of analysis. Impacts high-availability clustering infrastructure commonly used in enterprise production environments.

Use-after-free in Linux kernel AppArmor allows local authenticated attackers to achieve high-impact code execution, privilege escalation, or denial of service via race condition on rawdata inode dereference. Affects kernel 4.13+ including current LTS branches. Patches available for 6.6.130, 6.12.77, 6.18.18, 6.19.8, and 7.0-rc4. EPSS score is low (0.02%) with no public exploit identified at time of analysis, but Ubuntu rated this priority=high affecting 729 releases.

AppArmor differential encoding verification in the Linux kernel contains logic errors that permit infinite loops to be created through abuse of the verification chain mechanism. Two distinct bugs in the verification routine-conflation of checked states with currently-checked states, and incorrect loop iterator comparison-allow malformed differential encoding chains to bypass security checks. This enables potential information disclosure or policy circumvention on systems relying on AppArmor mandatory access control. The vulnerability affects Linux kernel versions prior to fixes applied across multiple stable branches via kernel commits.

Stack exhaustion in AppArmor profile removal allows local denial of service by crafting deeply nested profiles that trigger recursive kernel stack consumption. The Linux kernel's AppArmor security module can be crashed by a local user with permission to load profiles via the apparmor_parser tool and trigger removal through sysfs, causing kernel stack overflow. The fix replaces recursive profile removal with an iterative approach to prevent stack exhaustion.

Use-after-free in Chrome's compositing engine allows remote attackers who have compromised the renderer process to escape the sandbox via crafted HTML pages in Google Chrome prior to version 146.0.7680.178. This high-severity vulnerability requires prior renderer compromise but enables privilege escalation from the sandboxed renderer to system-level access, making it a critical sandbox bypass vector. Vendor-released patch addresses the issue in Chrome 146.0.7680.178 and later.
