Denial Of Service

Heap overflow denial-of-service in NLnet Labs Unbound recursive DNS resolver versions 1.14.0 through 1.25.0 allows remote unauthenticated attackers to crash the resolver by sending DNS queries containing multiple NSID, DNS Cookie, and/or EDNS Padding options. The flaw stems from a numeric truncation in EDNS field size calculation that lets attacker-influenced data overflow the response buffer. No public exploit identified at time of analysis and not listed in CISA KEV, but the impact is service-wide DNS outage for any user of an affected resolver.

Unbound DNS resolver up to and including version 1.25.0 exposes a denial-of-service condition in its DNSSEC validation stack, specifically in the negative cache code path used to look up DS records. An adversary who controls a DNSSEC-signed zone can craft NSEC3 records with high-but-permissible iteration counts for child delegations, causing any vulnerable Unbound instance that queries those records to perform unbounded SHA-1 hash computations while holding a global negative cache lock - blocking all other threads that need cache access. No public exploit code exists and this is not listed in the CISA KEV catalog at time of analysis, but coordinated query floods against the vulnerable code path could escalate a single-instance slowdown into a full denial of service.

Unbound DNS resolver versions up to and including 1.25.0 allow remote unauthenticated attackers to degrade or deny service by sending DNS queries carrying abnormally large numbers of EDNS options, causing resolver threads to become occupied with unbounded parsing and internal data structure allocation. Coordinated multi-source attacks amplify thread exhaustion into full denial of service for legitimate DNS clients. No public exploit identified at time of analysis; vendor-released patch is available in Unbound 1.25.1, which enforces a hard cap of 100 incoming EDNS options.

Use-after-free in the DNSSEC validator of NLnet Labs Unbound resolver versions 1.19.1 through 1.25.0 allows remote attackers to crash the daemon or potentially achieve arbitrary code execution by serving a malicious signed zone to a vulnerable resolver. The flaw stems from a struct-assignment bug during deep copying of response messages when DS sub-queries suspend validation under NSEC3 computational budget exhaustion. No public exploit identified at time of analysis, but the CVSS 4.0 score of 9.1 with network attack vector and no required privileges or user interaction makes this a high-priority patching target for any operator running a recursive Unbound resolver.

Heap out-of-bounds read in Unbound's DNSCrypt packet handling allows a remote unauthenticated attacker to potentially crash the resolver with a single malformed query, causing denial of service. Affected are all Unbound installations from version 1.6.2 through 1.25.0 that were compiled with the optional '--enable-dnscrypt' flag. The crash is probabilistic rather than guaranteed - whether the out-of-bounds read escalates to a heap overflow depends entirely on the memory allocator behavior and heap layout at runtime; absent a crash, Unbound's own packet validation will discard the offending query. No public exploit exists and no active exploitation has been identified at time of analysis.

Unsafe deserialization in NVIDIA TensorRT-LLM's RPC testing component allows a local high-privileged attacker to trigger code execution, denial of service, data tampering, or information disclosure across a changed scope. The flaw is rated CVSS 7.5 despite local-only access and high attack complexity because successful exploitation crosses a security boundary (S:C) and yields full CIA impact. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

Null pointer dereference in NVIDIA TensorRT-LLM across all supported platforms allows a local attacker to crash the application and cause denial of service. The flaw stems from an unchecked return value that is subsequently dereferenced, triggering a fault when the returned pointer is null. With a CVSS score of 5.5 and no public exploit or CISA KEV listing identified at time of analysis, real-world risk is moderate and constrained by the local attack vector and mandatory user interaction.

Unsafe deserialization in NVIDIA TensorRT-LLM's MPI server component allows a high-privileged local attacker to achieve code execution, denial of service, data tampering, or information disclosure on systems running the affected library. The CVSS 7.5 score reflects high impact but constrained exploitability (AV:L/AC:H/PR:H), and no public exploit identified at time of analysis. Scope change (S:C) indicates compromise can extend beyond the vulnerable component to impact other resources on the host.

Uncontrolled resource consumption in NVIDIA Triton Inference Server's DALI backend allows a network-adjacent, low-privileged attacker to exhaust server resources, resulting in denial of service. The vulnerability (CWE-400) is triggered through the DALI data-loading and augmentation backend, requires low privileges and user interaction, and carries a CVSS score of 5.7 (Medium). No public exploit code or CISA KEV listing has been identified at time of analysis, placing this in a monitored-but-not-critical-urgency tier for most deployments.

Integer overflow in the DALI backend of NVIDIA Triton Inference Server allows authenticated remote attackers to trigger memory corruption that may result in code execution, data tampering, or denial of service. The flaw requires low-level privileges plus user interaction (CVSS 8.0, AV:N/AC:L/PR:L/UI:R) and affects deployments exposing the DALI inference pipeline. No public exploit identified at time of analysis.

Out-of-bounds read in the DALI backend of NVIDIA Triton Inference Server allows authenticated remote attackers to trigger memory disclosure that may escalate to code execution, data tampering, or denial of service. The flaw carries a CVSS 8.0 (High) rating reflecting low-privilege network access with required user interaction, and no public exploit identified at time of analysis. NVIDIA has published a security bulletin addressing the issue.

Denial of service in NVIDIA Triton Inference Server can be triggered remotely by unauthenticated attackers via an integer overflow condition (CWE-190). The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit has been identified at time of analysis. Defenders running Triton in network-exposed inference deployments should prioritize patching since exploitation requires no privileges, no user interaction, and low attack complexity.

Denial of service in NVIDIA Triton Inference Server can be triggered remotely without authentication via a path traversal flaw (CWE-22), enabling unauthenticated network attackers to disrupt model-serving availability. The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit has been identified at time of analysis.

Path traversal exploitation in NVIDIA Triton Inference Server enables unauthenticated remote attackers to cause denial of service by submitting crafted requests containing malicious path components. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms zero authentication or user interaction is required, making this broadly reachable from the network with low attack complexity. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog at time of analysis; however, the no-prerequisite attack profile warrants patching per NVIDIA's advisory at nvidia.custhelp.com.

Authentication bypass in NVIDIA Triton Inference Server allows unauthenticated remote attackers to reach protected functionality over the network, potentially chaining to code execution, privilege escalation, data tampering, denial of service, or information disclosure. The CVSS 9.8 vector (AV:N/AC:L/PR:N/UI:N) reflects a critical severity issue affecting an AI/ML inference platform commonly deployed in production model-serving environments. No public exploit identified at time of analysis, and the CVE is not currently listed in CISA KEV.

Authentication bypass in NVIDIA Triton Inference Server allows remote unauthenticated attackers to circumvent access controls, potentially leading to privilege escalation, denial of service, or information disclosure. With a CVSS 7.3 score and network-reachable attack vector (AV:N/AC:L/PR:N/UI:N), the flaw is exploitable without user interaction or credentials, though no public exploit identified at time of analysis. The vulnerability is not currently listed in CISA KEV, and EPSS data was not provided in the source intelligence.

Permanent denial of service in Ledger Nano X, Flex, and Stax hardware cryptocurrency wallets allows a physically present attacker to irreversibly brick the device by supplying a crafted reset_handler address during MCU firmware flashing. The firmware update process accepts attacker-controlled pointer values without bounds checking or range validation, causing the MCU to dereference an invalid instruction pointer at boot and enter an unrecoverable hardware fault state. No public exploit code is identified at time of analysis and the device is not listed in the CISA KEV catalog; the CVSS 4.0 score of 5.1 (Medium) reflects the mandatory physical access requirement, which substantially constrains the attacker population but does not diminish the severity of permanent device loss for affected users.

Denial of service via unbounded memory allocation in Joplin note-taking application versions 3.6.14 and prior crashes the application by exhausting system memory when an excessively long string is provided as a note title. Authenticated local users with access to the Joplin UI, or attackers holding a compromised local API token, can trigger this Out Of Memory condition through either direct UI interaction or an HTTP POST to the local web service API (default port 41184). No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, exploitation requires only low privileges and no user interaction once access is established.

Denial of service in SQLFluff parser (pip/sqlfluff) versions prior to 4.2.0 allows remote unauthenticated attackers to exhaust CPU and memory resources by submitting an excessively long or malicious SQL query for linting. The flaw affects any application that exposes the SQLFluff parser to untrusted input. No public exploit identified at time of analysis, but the issue was responsibly reported by Imperva Threat Research.

Denial of service in SQLFluff (Python SQL linter/parser) below version 4.1.0 allows remote attackers to exhaust server resources by submitting SQL queries with deliberately excessive nesting, triggering uncontrolled recursion in the parser. The flaw (CWE-674) affects any application that accepts untrusted SQL input for linting and carries a CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/A:H); no public exploit identified at time of analysis and EPSS data was not provided.

Denial of service in dasel (Go data selector library) versions 3.0.0 through 3.10.0 allows attackers who control selector query strings to pin a CPU core at 100% indefinitely via a 2-byte payload (`r/`). The selector lexer's `matchRegexPattern` closure lacks an end-of-input bounds check, causing an infinite loop when tokenizing unterminated regex literals. No public exploit identified at time of analysis beyond the reporter's PoC, and the issue is not listed in CISA KEV.

Denial of service in dasel (Go data selector library) v3.0.0 through v3.10.0 allows attackers who influence selector query strings to crash the host process via a 2-byte input. A trailing backslash inside a quoted selector (e.g., `"\` or `'\`) triggers an index-out-of-range panic in the lexer's escape-sequence handler. Publicly available exploit code exists (PoC in the GHSA advisory), and no public exploit identified at time of analysis indicates in-the-wild abuse.

Heap buffer over-read in libheif versions 1.21.2 and prior allows remote attackers to crash applications or potentially leak adjacent heap memory by supplying a crafted HEIF/AVIF file with an overlay image (iovl) whose alpha channel bit depth differs from its color channels. The flaw in HeifPixelImage::overlay() uses the color channel stride to index into the alpha plane, reading up to 3,123 bytes beyond the alpha buffer for a 100×50 image with 10-bit color and 8-bit alpha. No public exploit identified at time of analysis, and the issue is fixed in version 1.22.0.

Memory exhaustion and endless loop in Setasign FPDI (composer package setasign/fpdi) allow remote attackers to crash PHP server-side scripts by uploading a small, specially crafted PDF file. All versions prior to 2.6.7 are affected, and any web application that exposes FPDI-based PDF processing to user-supplied input is vulnerable. Repeated submissions can sustain service unavailability; no public exploit has been identified at time of analysis, and no CISA KEV listing exists.

Denial of service in Square Wire protobuf library (com.squareup.wire:wire-runtime before 6.3.0) allows remote unauthenticated attackers to crash any service that decodes untrusted protobuf payloads by sending a 10-byte crafted message. The flaw stems from missing negative-length validation in skipGroup(), causing an unchecked ArrayIndexOutOfBoundsException to escape Wire's documented IOException boundary. No public exploit identified at time of analysis, though the GitHub advisory includes a full reproduction payload and Java PoC code.

Denial of service in HAX CMS NodeJS (npm/@haxtheweb/haxcms-nodejs) allows any authenticated user to crash the entire Node.js server process with a single crafted HTTP POST to the createSite endpoint. The crash stems from a null pointer dereference (CWE-476) in HAXCMSFile.save(), where tmpFile.originalname is undefined, causing an unhandled TypeError that terminates the process immediately. Because HAX CMS permits open account self-registration, an attacker can create their own account and trigger the crash without needing to compromise existing credentials, making the effective barrier to exploitation very low despite the PR:L CVSS designation. No public exploit identified at time of analysis beyond the PoC included in the GitHub security advisory.

Denial of service in OpenMcdf versions up to and including 3.1.3 allows an attacker to permanently hang any thread that processes a crafted Compound File Binary (CFB) file by exploiting an unguarded infinite loop in the BST name-lookup path of DirectoryTree.TryGetDirectoryEntry. The flaw is distinct from - and unaddressed by - the Brent's-algorithm cycle detection added to DirectoryTreeEnumerator in commit 24f445a: while EnumerateEntries() now safely throws a FileFormatException on cyclic input, any subsequent call to OpenStorage(), TryOpenStorage(), OpenStream(), or TryOpenStream() enters the unprotected while-loop and spins at 100% CPU indefinitely. Publicly available proof-of-concept CFB files (5,632 and 7,936 bytes) demonstrate the hang via two distinct API paths; no public exploit identified at time of analysis that escalates beyond DoS, and the vulnerability is not listed in the CISA KEV catalog.

Unauthenticated remote code execution in 9router (npm package) versions 0.4.30 through 0.4.36 allows network-adjacent attackers to execute arbitrary OS commands by chaining two unprotected API endpoints. The Next.js authentication middleware in src/proxy.js uses a narrow route allowlist that excludes /api/cli-tools/* and /api/mcp/*, letting an attacker register an arbitrary command via POST /api/cli-tools/cowork-settings and then trigger spawn() via GET /api/mcp/[plugin]/sse. Publicly available exploit code exists (PoC published with the GHSA advisory), with CVSS 10.0 reflecting maximum severity across confidentiality, integrity, and availability.

Infinite CPU loop denial-of-service in libheif 1.21.2 and below allows a remote unauthenticated attacker to permanently exhaust a victim application's CPU by delivering a crafted 800-byte HEIF sequence file. The vulnerability triggers during file parsing in Box_stts::get_sample_duration() before any image decoding occurs, meaning any application that opens user-supplied HEIF files is exposed at the moment of file open. No KEV listing and no public exploit have been identified at time of analysis, but the low attack complexity and high availability impact make this a meaningful risk for deployments that process untrusted HEIF content. Vendor-released patch version 1.22.0 resolves the issue.

Denial of service in libheif versions 1.21.2 and below allows a remote attacker to crash any application linked against the library by supplying a crafted HEIF sequence file. The crash is deterministic - the malformed file passes parsing without error, then triggers a guaranteed SEGV on the first frame access due to an unsigned integer underflow that maps all media samples to an empty chunk. No public exploit has been identified at time of analysis, and this is not listed in the CISA KEV catalog; vendor-released patch is available in version 1.22.0.

Remote unauthenticated denial-of-service in NanoMQ MQTT Broker (versions 0.24.10 and below) crashes the broker process via a NULL pointer dereference triggered by high-concurrency MQTT reconnect traffic. The flaw occurs during session resumption for persistent-session clients (clean_start=0), where the NanoNNG transport layer's pipe_peer() function dereferences cpipe->subinfol without verifying that the new pipe's subinfol pointer is also non-NULL - a pointer that can be freed mid-race. No public exploit code exists and the vulnerability is not listed in CISA KEV; however, CVSS AV:N/PR:N confirms remote unauthenticated triggering, and the fix has been released in version 0.24.11.

Unauthenticated remote denial-of-service in Mailpit versions prior to 1.30.0 allows network-reachable attackers to exhaust memory and disk by submitting arbitrarily large messages through the SMTP listener on port 1025 or the HTTP /api/v1/send endpoint on port 8025. The Server.MaxSize field exists but is never populated in production code, and the JSON decoder lacks http.MaxBytesReader, so a single connection delivering a 100 MiB DATA payload inflates RSS roughly tenfold (≈25 MiB → ≈1 GiB), and concurrent connections drive the process to OOM-kill. Publicly available exploit code exists (working SMTP and HTTP PoCs are included in the GHSA advisory), though no CISA KEV listing or EPSS score was supplied with this input.

Full process crash in Mailpit before v1.30.0 is achievable by a remote unauthenticated attacker via a race condition in the /proxy endpoint's CSS rewriter cache, causing Go's unrecoverable fatal runtime panic and terminating the SMTP, POP3, and HTTP listeners simultaneously. The root cause is an unsynchronized read of a package-level assets map[string]MessageAssets cache that is written concurrently by a cleanup goroutine and re-entrant CSS-rewriting handlers - Go's runtime detects the collision and calls throw(), which bypasses http.Server's handler-panic recovery. Publicly available exploit code exists in the GHSA advisory; no CISA KEV listing has been identified at time of analysis, and EPSS data was not available in the provided intelligence.

Resource exhaustion in the Python idna library's idna.encode() function allows denial-of-service via specially crafted Unicode inputs that bypass the incomplete CVE-2024-3651 remediation. Affected versions process CONTEXTO-class codepoints - such as Arabic-Indic digit zero (U+0660) or Katakana middle dot (U+30FB) - through the valid_contexto validation function before length rejection occurs, enabling arbitrarily large inputs to consume significant CPU. Any Python application that passes unvalidated user input to idna.encode() or related per-label/codec functions without upstream length enforcement is exposed; no public exploit has been identified at time of analysis beyond the PoC payloads embedded in the advisory itself.

Denial of service in Sparx Systems Pro Cloud Server 6.1 (build 167) and earlier allows authenticated remote attackers to crash the service by submitting a specially crafted SQL query that the server fails to parse safely. The flaw, reported by CERT-PL, results in unexpected termination of the Pro Cloud Server process, and no public exploit identified at time of analysis. The vendor did not respond to disclosure, so the full vulnerable version range remains unconfirmed.

Denial-of-service due to invalid pointer in the Audio/Video: Web Codecs component. This vulnerability was fixed in Firefox 151 and Firefox ESR 140.11.

Denial of service in Red Hat build of Keycloak allows remote unauthenticated attackers to exhaust CPU and worker threads by submitting specially crafted XML payloads to the SAML endpoint. The flaw renders the identity provider unavailable, disrupting authentication for all downstream applications relying on it. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

Denial-of-service in ExifReader (npm package mattiasw/ExifReader) before 4.39.0 allows remote attackers to exhaust memory by submitting a crafted image whose ICC profile contains a malformed mluc tag. A specially crafted record count combined with a zero record size causes the parser to loop on the same record while continuously appending entries to an array, driving memory growth until the host process crashes. CVSS 4.0 base score is 7.7 with proof-of-concept exploit maturity (E:P), and publicly available exploit code exists via the referenced gist; no active in-the-wild exploitation is indicated.

Use-after-free memory corruption in Samsung's Escargot JavaScript engine (commit 590345cc6258317c5da850d846ce6baaf2afc2d3) enables pointer manipulation when processing crafted JavaScript content, with CVSS 7.8 reflecting high-impact local exploitation requiring user interaction. The affected codepaths include evaluator error handling, TypedArray copyWithin operations on resizable buffers, DataView coercion, and array fast-mode transitions - all triggerable by attacker-controlled script. No public exploit identified at time of analysis and the CVE is not listed in CISA KEV.

NULL pointer dereference in Samsung's open-source Walrus WebAssembly runtime crashes the parser when processing malformed WASM binaries, resulting in denial of service. The vulnerability exists in the WASMBinaryReader component (WASMParser.cpp) at commit f339b8ee4ea701772e8ae640b3d1b12ac02b1ae9, where multiple error-handling code paths fail to return early, allowing execution to continue past invalid state and dereference null pointers. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.

NULL pointer dereference in OpenHarmony v6.0 and prior enables a local low-privileged attacker to crash the system or an affected process, causing a denial-of-service condition. The vulnerability is confined to local exploitation with no confidentiality or integrity impact, as reflected in the CVSS:3.1 score of 3.3 (Low). No public exploit code has been identified at time of analysis, and no active exploitation has been reported.

NULL pointer dereference in Samsung Open Source Walrus's WebAssembly binary parser causes application-level denial of service when a crafted .wasm module containing deeply nested instructions is loaded. The vulnerability affects the Walrus runtime at commit f339b8ee4ea701772e8ae640b3d1b12ac02b1ae9 (CPE: cpe:2.3:a:samsung_open_source:walrus) and is classified CVSS 5.5 Medium with a local attack vector requiring user interaction. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; an upstream fix is available in GitHub PR #409 but a tagged release version has not been independently confirmed.

Unauthenticated denial-of-service in AutoGPT Platform versions 0.4.2 through 0.6.51 allows remote attackers to exhaust server disk space by repeatedly invoking the download_agent_file endpoint, which creates temporary files that are never cleaned up. Once disk capacity is consumed, the backend database and dependent services fail with 'No space left on device' errors, taking the entire platform offline for all users. No public exploit identified at time of analysis, but the trivial nature of the attack (simple repeated HTTP requests) makes it readily reproducible.

Denial of service in ImageMagick's MIFF (Magick Image File Format) decoder allows remote unauthenticated attackers to trigger an infinite loop and exhaust CPU resources by submitting a crafted MIFF file. The flaw affects Magick.NET bindings prior to version 14.13.1 across multiple platform builds (Q16, HDRI, OpenMP variants for x64/arm64/x86) and is tracked under GHSA-7gg8-qqx7-92g5. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.

Denial-of-service via policy bypass in Magick.NET's MNG coder allows remote unauthenticated attackers to exhaust server resources by submitting crafted MNG image files that circumvent the library's configured image list limit. All Magick.NET NuGet package variants (Q16, Q16-HDRI, and OpenMP/ARM64/x64/x86 flavors) below version 14.13.1 are confirmed vulnerable. No public exploit exists and the vulnerability is not in CISA KEV at time of analysis, but the network-accessible, zero-authentication attack surface makes this an accessible DoS primitive for any application accepting user-supplied image input.

Regular expression denial-of-service (ReDoS) in HAPI FHIR's FHIRPathEngine allows remote unauthenticated attackers to exhaust CPU resources by submitting FHIR resources containing crafted FHIRPath expressions that invoke matches(), matchesFull(), or replaceMatches() with catastrophically backtracking regex patterns. Affected versions are org.hl7.fhir.* Maven artifacts at or below 6.9.6, with publicly available exploit code exists via the GitHub Security Advisory PoC (pattern (a+)+$ against a long string). CVSS 7.5 reflects high availability impact with no confidentiality or integrity loss; no public exploit identified in the wild and no CISA KEV listing.

Remote denial-of-service in OpenTelemetry eBPF Instrumentation (OBI) versions 0.7.0 through 0.8.x allows unauthenticated attackers to crash the privileged instrumentation process by sending a crafted memcached storage command with an oversized `<bytes>` field. The integer overflow in the memcached text protocol parser produces a negative payload length that triggers a Go runtime panic in LargeBufferReader.Peek, halting telemetry collection until OBI is restarted. Publicly available exploit code exists in the GHSA-43g7-cwr8-q3jh advisory, but there is no public exploit identified beyond the PoC and the vulnerability is not listed in CISA KEV.

Remote denial-of-service in OpenTelemetry eBPF Instrumentation (go.opentelemetry.io/obi) versions v0.1.0 through v0.8.0 allows unauthenticated attackers to crash the telemetry agent by sending malformed MongoDB wire protocol messages. The MongoDB TCP parser contains three uncaught panic conditions (two slice-bounds errors in parseOpMessage/parseSections, and an unchecked BSON type assertion in parseFirstField) that terminate telemetry collection for the affected process or node. Publicly available exploit code exists in the form of self-contained Go test reproductions published in the GHSA advisory.

CPU exhaustion in OpenTelemetry eBPF Instrumentation (OBI) versions prior to 0.9.0 allows remote attackers to indirectly cause availability degradation of the privileged monitoring agent by generating high-volume traffic through instrumented services. The internal Prometheus metrics exporter replays BPF probe hits in a tight loop proportional to the raw hit count rather than the number of metric series, creating unbounded CPU work per collection interval. A proof-of-concept reproducer has been confirmed and published in the GitHub Security Advisory (GHSA-89c6-vpcj-7vj4); no public exploit identified at time of analysis beyond the PoC.

Arbitrary file deletion in DumbAssets through 1.0.11 lets unauthenticated remote attackers destroy any file the Node.js process can write to by submitting `../` sequences in the `filesToDelete` array of the `POST /api/delete-file` endpoint. Because authentication on the application is optional and disabled by default, exposed instances can be rendered completely non-functional by deleting critical files such as `server.js` or `package.json`. No public exploit identified at time of analysis, and the CVE is not currently on the CISA KEV list.

Signed integer overflow in the NetBSD kernel's cryptodev subsystem (sys/opencrypto/cryptodev.c, prior to commit ec8451e) enables a local low-privileged attacker to crash the kernel via a NULL pointer dereference, causing a full denial of service. The type mismatch between a signed int local variable and an unsigned cop->dst_len source value in cryptodev_op() produces undefined behavior when dst_len exceeds INT_MAX, corrupting UIO pointer arithmetic and - when CONFIG_SVS is disabled - triggering a kernel panic. No public exploit identified at time of analysis, though a technical writeup at nasm.re documents related memory-handling issues in this subsystem.

Denial of service in OpenTelemetry eBPF Instrumentation (OBI) versions prior to 0.9.0 allows remote attackers to crash the telemetry agent by sending a malformed Postgres BIND frame with an empty or unterminated portal name payload to any monitored service. The defect lives in OBI's passive Postgres protocol parser, where missing NUL-terminator validation causes a Go slice-bounds panic, halting telemetry collection on the affected node. Publicly available exploit code exists in the GHSA-pgvv-q3wf-mm9m advisory, though the issue is not listed in CISA KEV and EPSS data was not provided.

OBI's custom fastelf ELF parser in opentelemetry-ebpf-instrumentation crashes when processing malformed ELF binaries during routine process discovery on Linux hosts. Local users with standard execution rights can place or run a binary with corrupted section-header fields (Shoff, Shnum, or string-table offsets), causing the agent to panic inside matchExeSymbols, GetCStringUnsafe, or ReadStruct and terminate entirely. No public widespread exploitation has been identified and this is not listed in CISA KEV, but a PoC is confirmed in the GitHub Security Advisory (GHSA-wp73-mwgf-4jq9); the practical impact is a loss of observability for all workloads on the affected host.

Policy bypass in Magick.NET's PSD decoder allows remote unauthenticated attackers to circumvent the configured `list-length` resource policy when processing Photoshop Document (PSD) images, resulting in partial availability impact (CWE-400 uncontrolled resource consumption). All Magick.NET NuGet package variants prior to version 14.13.1 are affected across multiple architectures and quantization depths. No public exploit identified at time of analysis and no CISA KEV listing exists; however, the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates that any internet-exposed application accepting PSD uploads is reachable without authentication or special conditions.

Symlink-based race condition in Docker Engine's `docker cp` implementation allows a malicious container with at least one volume mount to redirect a bind mount to an arbitrary host filesystem path, enabling host file overwrite or temporary denial of service. The flaw affects Moby/Docker through 28.5.2 and is fixed only in the Moby v2 line (2.0.0-beta.14); no public exploit identified at time of analysis. Exploitation requires an operator-initiated `docker cp` or archive API call against the malicious container, which constrains real-world abuse to environments where untrusted containers receive file copies.

Race condition in Docker's `docker cp` mount setup allows a process running inside a malicious container to create empty files or directories at arbitrary absolute paths on the host filesystem as root. Affected packages include github.com/docker/docker <= 28.5.2 and github.com/moby/moby <= 28.5.2, with a patch only confirmed for the moby/moby v2 branch at 2.0.0-beta.14. The CVSS vector reflects a scope-changed (S:C), high-availability-impact flaw requiring low privileges and high complexity; no public exploit or CISA KEV listing has been identified at time of analysis, but the attack is realistic when operators use `docker cp` against containers running untrusted workloads with volume mounts.

Prototype pollution in the npm package parse-nested-form-data version 1.0.0 and earlier allows unauthenticated remote clients to mutate Object.prototype of the running Node.js process by submitting a FormData field whose name contains __proto__ in bracket or dot notation. The flaw resides in handlePathPart in src/index.ts, which walks nested path segments without filtering reserved keys, so a single crafted field name pollutes the prototype chain of every plain object in the process. No public exploit identified at time of analysis, but a working proof-of-concept is published in the GHSA advisory itself.

Remote unauthenticated denial-of-service in the Go Avro decoder github.com/iskorotkov/avro/v2 (and the archived upstream github.com/hamba/avro/v2) lets a single malformed payload pin a CPU core indefinitely. Array and map decoders iterate over an attacker-controlled block-count up to math.MaxInt64 (~9.2×10^18) without checking the reader's error state, so a truncated payload turns into a near-infinite no-op loop until the process is OOM-killed or externally terminated. No public exploit identified at time of analysis, but a regression test (TestDecoder_ArrayMultiBlockExceedsMaxInt) and a minimal POC payload are documented in the advisory.

Denial-of-service in the iskorotkov/avro Go Avro decoder (and its upstream hamba/avro v2 ancestor) allows remote unauthenticated attackers to crash decoding processes or bypass slice/map allocation caps by submitting crafted Avro streams whose 64-bit wire values trigger integer truncation, signed-int cumulative overflow, or negative-size make() panics. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/A:H) reflects pure availability impact; no public exploit identified at time of analysis, though the advisory itself documents detailed proof-of-concept inputs and a regression test demonstrating cap bypass on amd64.

{1..10000000}`. Despite the caller configuring a `max` limit, the sequence generation loop constructs the full intermediate array - allocating ~505 MB of heap and blocking the Node.js event loop for ~800ms - before truncation is applied. No public exploit has been identified at time of analysis, and a vendor-released patch is available in version 5.0.6.

Destructive file operations in the CI4MS Fileeditor module (composer/ci4-cms-erp/ci4ms ≤ v0.31.8.0) allow an authenticated backend user to delete or rename arbitrary framework files - including the front controller, routing config, and authentication filter pipeline - producing a persistent denial of service that requires filesystem-level redeployment to recover. The root cause is an inconsistent application of the existing extension allowlist: while saveFile and createFile correctly gate writes through allowedFileTypes(), the deleteFileOrFolder and renameFile endpoints apply no such check to the source path, meaning any file inside ROOTPATH not named in the narrow $hiddenItems blocklist is reachable. A working curl-based proof-of-concept is publicly available via GitHub advisory GHSA-245j-xjvr-xvm5; no CISA KEV listing is present at time of analysis.

Denial of service in MongoDB Server 7.0, 8.0, and 8.2 allows authenticated remote attackers to crash the database by inserting documents that trigger updates to a maliciously created '2dsphere_bucket' or 'queryable_encrypted_range' index on a non-timeseries bucket collection. The flaw stems from a reachable assertion (CWE-617) and is reported by MongoDB itself with a vendor patch available; no public exploit identified at time of analysis.

Broken access control in Arcane's GitOps backend (versions <= 1.18.1) allows any authenticated low-privilege user to exfiltrate plaintext Git credentials (PATs/SSH keys) stored for source-of-truth repositories. Eight of nine /api/customize/git-repositories endpoints omit the checkAdmin() gate, letting a 'user' role attacker repoint a repository URL to an attacker-controlled host and trigger a /test or /branches call that transmits the decrypted token via HTTP Basic auth. No public exploit identified at time of analysis, but the GHSA advisory documents a complete attack chain and a patched release (1.19.0) is available.

Prototype pollution in the npm package form-data-objectizer (<= 1.0.0) lets unauthenticated remote attackers mutate Object.prototype by submitting a single HTTP form field whose name uses bracket notation such as __proto__[polluted] or constructor[prototype][polluted]. The defect lives in treatInitial/treatSecond inside index.cjs, where an 'in' check walks the prototype chain and lets the parser write to inherited properties. CVSS is 8.2 (High) with Integrity:High; publicly available exploit code exists (working PoC published in the GHSA advisory), but there is no public exploit identified as being used in attacks and no CISA KEV listing.

Denial of service in GnuTLS affects the Datagram Transport Layer Security (DTLS) packet reordering logic, where the comparator function fails to correctly handle packets with duplicate sequence numbers. Remote unauthenticated attackers can send specially crafted DTLS packet sequences to trigger unstable ordering or undefined behavior, causing service disruption. No public exploit identified at time of analysis, and the issue is rated CVSS 7.5 (High) for availability impact only.

The flaw is reachable over the network with low privileges and no user interaction, but has no impact on confidentiality or integrity. No public exploit identified at time of analysis, and the issue is not present in CISA KEV.

Mattermost Desktop App can be repeatedly crashed by malicious server administrators through JavaScript URL injection in pop-up windows. Attackers controlling a Mattermost server can force connected desktop clients to become unusable by exploiting improper URL validation, requiring user interaction (connecting to the malicious server). No public exploit code identified at time of analysis, though the attack method is trivial to implement given the disclosed details.

Mattermost Desktop App can be crashed remotely by malicious server administrators or plugin developers exploiting insufficient isolation of server-rendered content. Authenticated attackers with low-privilege server access who can control rendered content (via compromised server, malicious plugin, or modified server responses) can invoke window.close() to terminate the desktop client, causing a client-side denial of service. EPSS data not available; no public exploit code identified at time of analysis. CVSS 3.5 (Low severity) reflects limited impact scope - disruption to individual user sessions rather than system-wide compromise.

Memory exhaustion denial of service in Mattermost Server versions 11.5.x through 11.5.1, 10.11.x through 10.11.13, and 11.4.x through 11.4.3 allows authenticated attackers to crash the server by uploading maliciously crafted 7zip archives containing excessive folder declarations. The vulnerability stems from insufficient validation of 7zip archive structure before decompression, enabling resource exhaustion attacks with low attack complexity. EPSS data not available, not listed in CISA KEV, indicating no confirmed widespread exploitation at time of analysis.

Resource exhaustion in Mattermost Server 10.11.x through 11.5.1 allows authenticated users to trigger denial of service by sending oversized HTTP POST requests to the /api/v1/meetings endpoint.

In tinyMQTT commit 6226ade15bd4f97be2d196352e64dd10937c1962 (2024-02-18), the broker mishandles protocol violations during CONNECT packet parsing. When receiving a CONNECT packet with a zero-length Client ID while CleanSession is set to 0, the broker correctly replies with a CONNACK return code 0x02 (Identifier Rejected) but fails to explicitly close the TCP connection. Since the surrounding connection teardown logic is not guaranteed to execute, each such invalid CONNECT attempt leaves the underlying socket open. Repeated attempts cause server-side resource exhaustion due to accumulating file descriptors and memory usage, potentially resulting in denial of service.
