Memory corruption via integer overflow in Mozilla Firefox's ImageLib graphics component allows remote attackers to potentially achieve code execution by serving a maliciously crafted image, with the flaw resolved in Firefox 153. The CVSS 9.8 rating reflects unauthenticated network reach with high impact to confidentiality, integrity, and availability, though no public exploit has been identified and the EPSS probability of 0.13% (3rd percentile) indicates no observed exploitation activity to date. It is not listed in CISA KEV and there is no public exploit identified at time of analysis.
Privilege escalation in Mozilla Firefox's Data Loss Prevention (DLP) component allows an attacker to gain elevated privileges beyond those intended for the affected process or policy context, with all confidentiality, integrity, and availability impacts rated high. Mozilla assigned a CVSS base score of 9.8, though the network/unauthenticated vector conflicts with the 'privilege escalation' framing typical of local flaws. There is no public exploit identified at time of analysis, and EPSS estimates only a 0.13% exploitation probability (3rd percentile), indicating low near-term real-world weaponization despite the high CVSS.
Information disclosure in Mozilla Firefox's DOM: Security component allows remote attackers to read sensitive cross-origin or in-process data via crafted web content, undermining the browser's same-origin and security boundary enforcement. Any Firefox version prior to 153 is affected, and exploitation is remote and unauthenticated with no user interaction beyond visiting a malicious page. The issue was reported and fixed by Mozilla; no public exploit identified at time of analysis and EPSS exploitation probability is low (0.13%).
Cross-origin information disclosure in Mozilla Firefox's DOM: Navigation component allows a malicious web page to bypass site isolation (Fission) boundaries and read data belonging to another origin. The flaw affects Firefox versions prior to 153 and is remotely reachable over the network with no privileges required, though impact is limited to confidentiality. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.13%).
Information disclosure in Mozilla Firefox before version 153 stems from a site isolation weakness in the Graphics component, allowing a remote attacker to read cross-origin data that should be siloed between sites. The confidentiality-only flaw (CVSS 7.5, C:H) is network-reachable without authentication or user interaction, but carries no public exploit and a low EPSS score (0.13%, 3rd percentile), indicating theoretical rather than active risk. It is not listed in CISA KEV; no public exploit identified at time of analysis.
Privilege escalation in the WebExtensions subsystem of Mozilla Firefox lets a WebExtension gain capabilities beyond its granted permission set, corresponding to CWE-269 (Improper Privilege Management). Mozilla, the reporting vendor, fixed the issue in Firefox 153 and Firefox ESR 140.13 (advisories MFSA2026-68/70/71/72). No public exploit has been identified at time of analysis and the EPSS probability is low at 0.14% (4th percentile), despite the vendor-supplied 9.8 CVSS score.
Memory-corruption via an integer overflow in Mozilla Firefox's Audio/Video component allows remote attackers to compromise the browser when a victim processes attacker-controlled media, with the CVSS 9.8 vector (AV:N/AC:L/PR:N/UI:N) indicating unauthenticated network exploitation and high impact to confidentiality, integrity, and availability. The flaw was fixed in Firefox 153 per Mozilla advisory MFSA2026-68. There is no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
Protection mechanism failure in the DOM: Security component of Mozilla Firefox lets remote attackers bypass a browser security mitigation, undermining defenses that isolate web content and enforce origin/policy boundaries. Mozilla rates this Critical (CVSS 9.1) with high confidentiality and integrity impact and no authentication or user interaction required per the assigned vector; it is corrected in Firefox 153 (MFSA 2026-68). There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Memory corruption in the Audio/Video Gecko Media Plugin (GMP) component of Mozilla Firefox lets remote attackers trigger a buffer overflow through crafted media content, which per CVSS can disclose sensitive process memory and corrupt process state (C:H/I:H). The flaw affects Firefox before 153 and the ESR 115.x and 140.x branches; Mozilla shipped fixes in Firefox 153, ESR 115.38, and ESR 140.13. There is no public exploit identified at time of analysis and it is not in CISA KEV, but the 9.1 CVSS reflects an unauthenticated, network-reachable memory-safety bug in a core browser subsystem.
Memory corruption in Mozilla Firefox's WebGPU graphics component (fixed in Firefox 153) lets a remote attacker serving crafted web content trigger an out-of-bounds memory operation, enabling sensitive memory disclosure and browser crashes. The flaw is a CWE-119 boundary-condition error rated CVSS 9.1 (C:H/A:H, no integrity impact), consistent with an information-leak-plus-denial-of-service primitive rather than confirmed code execution. No public exploit identified at time of analysis, and EPSS is low (0.13%, 3rd percentile), indicating no evidence of active exploitation despite the high base score.
Information disclosure in Mozilla Firefox's Storage: IndexedDB component allows a remote attacker to leak sensitive data across origins or from other browsing contexts without authentication or user interaction. The flaw affects Firefox releases prior to 153 and ESR builds prior to 140.13; there is no public exploit identified at time of analysis, and its EPSS score (0.15%, 5th percentile) indicates low near-term exploitation likelihood despite a CVSS of 7.5. Mozilla has released fixed builds, so the practical priority is prompt browser updating rather than emergency response.
Protection-mechanism bypass in Mozilla Firefox's Enterprise Policies component allows attackers to circumvent security restrictions that administrators enforce through managed policy, undermining controls an organization relies on to lock down the browser. Mozilla rates the flaw CVSS 9.1 (network vector, low complexity, no privileges or user interaction) affecting Firefox before 153 and Firefox ESR before 140.13. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.16%, 6th percentile).
Sandbox escape in Mozilla Firefox's DOM: Networking component allows a remote attacker to break out of the content-process security boundary, fixed in Firefox 153. Rated CVSS 9.8, it maps to CWE-693 (Protection Mechanism Failure) and is tagged as an information-disclosure issue by Mozilla, meaning a compromised or malicious web page could bypass the browser's isolation to reach host resources. No public exploit identified at time of analysis, and the EPSS score is low (0.14%, 4th percentile), indicating no observed exploitation activity yet.
Information disclosure in Mozilla Firefox and Firefox ESR stems from a site isolation flaw in the Networking component, letting a malicious web page bypass cross-origin process/security boundaries and access data belonging to other sites. The issue was reported by Mozilla and fixed in Firefox 153 and Firefox ESR 140.13; no public exploit identified at time of analysis, and EPSS exploitation probability is low at 0.15% (5th percentile).
Information disclosure in Mozilla Firefox's Graphics WebGPU component allows a malicious web page to read uninitialized process memory, potentially leaking sensitive data such as heap contents, pointers, or cross-origin material, before the fix in Firefox 153. The flaw stems from WebGPU operating on memory that was never initialized (CWE-908), and while CVSS rates confidentiality impact High (7.5), EPSS is very low (0.14%, 4th percentile) with no public exploit and no CISA KEV listing. Exploitation is browser-based, requiring a victim to load attacker-controlled WebGPU content.
Information disclosure in Mozilla Firefox's Graphics WebGPU component allows a remote attacker to read leftover uninitialized memory, potentially exposing sensitive data such as other pages' content, GPU buffers, or process memory. The flaw stems from a WebGPU code path returning memory that was never zeroed, and is fixed in Firefox 153; there is no public exploit identified at time of analysis and the EPSS score is low (0.14%, 4th percentile).
Information disclosure in Mozilla Firefox's Graphics: WebGPU component allows remote attackers to read uninitialized memory contents via crafted WebGPU operations, potentially leaking sensitive process memory such as heap data, addresses, or other page content. The flaw is network-reachable without authentication or user interaction beyond visiting a malicious page, but carries no integrity or availability impact. There is no public exploit identified at time of analysis, and EPSS estimates a low 0.14% exploitation probability.
Security-mitigation bypass in Mozilla Firefox's DOM: Networking component undermines a built-in protection mechanism (CWE-693), potentially allowing crafted web content to defeat network-layer defenses in versions prior to Firefox 153 and ESR 140.13. The issue was reported and patched by Mozilla with no public exploit identified at time of analysis; EPSS is very low (0.16%, 6th percentile) and it is not listed in CISA KEV. The NVD-assigned CVSS of 9.8 (network, no auth, no user interaction) sits in tension with the sparse 'mitigation bypass' description, which typically describes a defense-defeating enabler rather than direct code execution.
Protection-mechanism bypass in Mozilla Firefox's DOM Service Workers component allows remote web content to circumvent a browser security mitigation, weakening defenses that normally contain untrusted script. The flaw affects Firefox versions prior to 153 and was reported and patched by Mozilla (MFSA2026-68). No public exploit has been identified at time of analysis, and EPSS estimates exploitation probability at only 0.15% (5th percentile), indicating no observed weaponization despite the high nominal CVSS score.
Same-origin policy bypass in Mozilla Firefox's Networking DNS component allows remote attackers to circumvent origin isolation and read or manipulate data belonging to other web origins. Affects Firefox before 153 and Firefox ESR before 140.13, exploitable over the network without authentication or user interaction (CVSS 9.1). No public exploit identified at time of analysis; EPSS is low (0.16%, 6th percentile).
Protection mechanism bypass in the Networking component of Mozilla Firefox (versions prior to 153) allows remote attackers to circumvent a built-in security mitigation over the network without authentication or user interaction, per the CVSS vector (AV:N/AC:L/PR:N/UI:N). Mozilla (MFSA2026-68) tags this as an authentication/mitigation bypass with high confidentiality and integrity impact but no availability impact. No public exploit identified at time of analysis, and EPSS exploitation probability is low at 0.15% (5th percentile).
Cross-origin information disclosure in Mozilla Firefox arises from a site isolation weakness in the Graphics: WebRender rendering component, where origin boundaries are not correctly enforced during GPU-accelerated compositing. An attacker-controlled web page loaded by a victim could leak data belonging to a different origin, undermining the same-origin protections that site isolation is meant to guarantee. Mozilla fixed the issue in Firefox 153, Firefox ESR 115.38, and Firefox ESR 140.13; there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.15%, 5th percentile).
Privilege escalation in Mozilla Firefox's DOM Content Processes component allows an attacker who influences a sandboxed content process to break out of the renderer sandbox and gain elevated privileges on the host, affecting Firefox before 153 and Firefox ESR before 140.13. Mozilla assigns a critical CVSS of 9.8, though the 'content process' scope suggests the practical entry point is attacker-controlled web content rather than a fully unauthenticated network service. No public exploit is identified at time of analysis, and the EPSS exploitation probability is very low (0.15%, 5th percentile).
Information disclosure in Mozilla Firefox before version 153 stems from an input-validation flaw in the DOM Copy & Paste and Drag & Drop component, allowing remote content to potentially read data that should remain isolated. The provided CVSS vector rates confidentiality impact as High with no privileges or user interaction, and Mozilla has shipped a fix in Firefox 153. There is no public exploit identified at time of analysis, and the EPSS score of 0.14% (4th percentile) indicates low near-term exploitation likelihood.
Mitigation bypass in the Mozilla Firefox PDF Viewer component undermines a built-in security control (CWE-693 Protection Mechanism Failure), weakening a defense-in-depth barrier that would otherwise contain malicious PDF content. Mozilla self-reported the issue and shipped fixes in Firefox 153 and Firefox ESR 140.13 via advisories MFSA2026-68 and MFSA2026-70. There is no public exploit identified at time of analysis, and EPSS is very low (0.16%, 6th percentile), so the headline CVSS 9.8 reflects worst-case potential rather than demonstrated mass exploitation.
Remote denial-of-service in Mozilla Firefox's Graphics: WebGPU component allows a malicious web page to exhaust browser resources and crash or hang the browser without any user credentials or interaction. The flaw affects Firefox versions prior to 153 and is triggered simply by loading attacker-controlled content that abuses the WebGPU API. There is no public exploit identified at time of analysis, and EPSS scores the exploitation likelihood at only 0.14%, indicating low near-term probability of widespread exploitation.
Cross-origin information disclosure in Mozilla Firefox and Firefox ESR stems from a site isolation weakness in the Networking: HTTP component (CWE-346, origin validation error), letting a malicious web page bypass origin boundaries to read data belonging to another site. It affects Firefox before version 153 and Firefox ESR before 140.13 and is addressed in Mozilla advisories MFSA2026-68 and MFSA2026-70. There is no public exploit identified at time of analysis, and the EPSS score is low (0.15%, 5th percentile), indicating no observed weaponization despite the vendor's 9.8 CVSS rating.
Information disclosure in the Firefox DevTools Framework component allows an attacker to read data that should remain isolated, affecting Mozilla Firefox prior to 153 and Firefox ESR prior to 140.13. Reported by Mozilla and carrying a CVSS 7.5 (high) rating driven by high confidentiality impact, there is no public exploit identified at time of analysis and the EPSS probability is low at 0.15% (5th percentile). The issue is fixed and not listed in CISA KEV.
Information disclosure in the Privacy component of Mozilla Firefox for Android allows remote attackers to expose sensitive user data, with the flaw carrying a high confidentiality impact (CVSS 7.5). Mozilla self-reported and fixed the issue in Firefox 153 per advisory MFSA2026-68; there is no public exploit identified at time of analysis, and the EPSS probability is low (0.14%, 4th percentile). The Privacy component context suggests leakage of protected browsing state or user data that the browser is designed to isolate.
Privilege escalation in Mozilla Firefox's DOM Content Processes component allows attackers to escape or elevate beyond the sandboxed content process, gaining higher browser privileges on affected versions prior to Firefox 153. The flaw is a CWE-269 improper privilege management issue reported by Mozilla and patched in Firefox 153 (advisory MFSA2026-68). No public exploit has been identified and EPSS is low (0.14%, 4th percentile), indicating no observed exploitation activity at time of analysis despite the high CVSS 9.8 rating.
Protection-mechanism bypass in the DOM: Networking component of Mozilla Firefox lets a remote, unauthenticated attacker circumvent a browser security mitigation, exposing confidential data and enabling integrity compromise (CVSS 9.1) without user interaction. Reported by Mozilla and fixed in Firefox 153, the flaw affects users browsing to attacker-controlled web content. No public exploit identified at time of analysis, and the low EPSS score (0.15%) suggests exploitation is not yet widespread.
Memory corruption in the Graphics component of Mozilla Firefox stems from incorrect boundary conditions (a buffer overflow) that can be triggered when the browser processes maliciously crafted graphics content, potentially leading to arbitrary code execution in the content process. It affects Firefox before 153, Firefox ESR before 115.38, and Firefox ESR before 140.13, and is fixed across those releases per Mozilla advisories MFSA2026-68/69/70. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.15%, 5th percentile) despite the vendor-supplied CVSS of 9.8.
Sandbox escape via use-after-free in Mozilla Firefox's Disability Access (accessibility) APIs allows an attacker who has compromised the content process to break out of the browser sandbox and gain code execution at the host privilege level. It affects Firefox before 153 and the ESR 115.x and 140.x branches, was reported and patched by Mozilla, and carries no public exploit at time of analysis. EPSS is low (0.15%, 5th percentile) and it is not on CISA KEV, indicating no observed exploitation.
Memory corruption in Mozilla Firefox's JavaScript engine JIT compiler allows attackers to corrupt memory and potentially achieve arbitrary code execution when a victim visits a malicious web page. The flaw stems from a JIT miscompilation (type confusion, CWE-843) affecting Firefox before 153, ESR before 115.38, and ESR before 140.13, and carries CVSS 9.8. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.15%, 5th percentile).
Memory corruption in Mozilla Firefox's JavaScript WebAssembly engine, stemming from an integer overflow (CWE-190), can be triggered by attacker-controlled web content and was patched in Firefox 153 and Firefox ESR 140.13. Reported by Mozilla and tracked as EUVD-2026-46202/MFSA2026-68 & MFSA2026-70, the flaw carries a 9.8 CVSS rating implying potential remote code execution, though no public exploit identified at time of analysis and EPSS exploitation probability is low at 0.15% (5th percentile).
Memory corruption in Mozilla Firefox's WebAssembly (JavaScript) engine allows remote attackers to trigger a buffer overflow through incorrect boundary condition handling, potentially leading to arbitrary code execution in the browser content process. The flaw carries a critical CVSS 9.8 and affects Firefox prior to version 153 and Firefox ESR prior to 140.13; it is fixed in those releases per Mozilla advisories MFSA2026-68 and MFSA2026-70. There is no public exploit identified at time of analysis, and the low EPSS score (0.15%) suggests exploitation in the wild has not yet been observed.
Sandbox escape in Mozilla Firefox before version 153 stems from an invalid pointer (CWE-119 memory-safety error) in the Disability Access (accessibility) APIs component, letting an attacker who can execute code in a constrained content process break out of the browser sandbox and reach the more privileged parent process with full confidentiality, integrity, and availability impact (CVSS 10.0, scope-changed). No public exploit identified at time of analysis, and the EPSS probability is low (0.14%, 4th percentile), indicating no evidence of widespread exploitation despite the maximum CVSS score.
Information disclosure in Mozilla Firefox's ImageLib graphics component allows remote attackers to read sensitive data (likely uninitialized or out-of-bounds process memory) when a victim renders attacker-controlled image content, per the CWE-200 classification and the C:H CVSS impact. Affected builds are Firefox before 153 and the ESR 115.x and 140.x branches, all fixed by Mozilla in Firefox 153, ESR 115.38, and ESR 140.13. There is no public exploit identified at time of analysis and EPSS is low (0.15%, 5th percentile), consistent with a vendor-reported browser memory-disclosure issue rather than one under active exploitation.
Memory corruption in Mozilla Firefox's DOM Bindings (WebIDL) layer allows a remote attacker who serves malicious web content to trigger a use-after-free (CWE-416) via an invalid/dangling pointer, potentially leading to arbitrary code execution or information disclosure in the content process. All Firefox and Firefox ESR builds prior to the fixed releases are affected. There is no public exploit identified at time of analysis, and the low EPSS score (0.15%, 5th percentile) suggests exploitation is not yet observed in the wild, though Mozilla rates the memory-safety impact as high.
Privilege escalation in Mozilla Firefox's DOM Navigation component (fixed in Firefox 153) allows an attacker to improperly gain elevated privileges within the browser, per Mozilla advisory MFSA2026-68. The flaw carries a CVSS 9.8 rating claiming full confidentiality, integrity, and availability impact with no privileges or user interaction, though this is atypical for a browser DOM bug. There is no public exploit identified at time of analysis, and EPSS exploitation probability is low (0.14%, 4th percentile).
Memory-corruption in Mozilla Firefox's Audio/Video Playback component allows a remote attacker to achieve confidentiality and integrity compromise (potentially arbitrary code execution) by delivering crafted media content to a victim's browser. Rooted in incorrect boundary conditions (buffer overflow, CWE-119), the flaw affects Firefox versions prior to 153 and carries a CVSS 9.1 rating, though EPSS exploitation probability is low (0.14%, 4th percentile) and no public exploit identified at time of analysis.
Memory-safety corruption in Mozilla Firefox stems from a JIT miscompilation in the JavaScript engine's WebAssembly component, fixed in Firefox 153 and Firefox ESR 140.13. An attacker who lures a victim to a malicious page can supply crafted WebAssembly that the Just-In-Time compiler translates incorrectly, corrupting engine state to disclose memory or achieve code execution in the content process. There is no public exploit identified at time of analysis and the EPSS score is very low (0.15%, 5th percentile), so no active exploitation is indicated despite the 9.8 rating.
Sandbox escape in Mozilla Firefox stems from a use-after-free in the Disability Access (accessibility) APIs, letting an attacker who already controls a sandboxed content process break out of the browser sandbox and compromise the host. It affects Firefox before 153 and the ESR 115.x and 140.x branches, with high impact to confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and the EPSS score is low (0.15%, 5th percentile), indicating no observed widespread exploitation.
Sandbox escape in Mozilla Firefox stems from a use-after-free (CWE-416) in the DOM: Navigation component, letting web-reachable content corrupt memory and cross the content-process sandbox boundary. Affected builds are Firefox before 153, Firefox ESR before 115.38, and Firefox ESR before 140.13; Mozilla self-reported the issue and shipped fixes across all three branches (MFSA-2026-68/69/70). There is no public exploit identified at time of analysis, and EPSS is low (0.15%, 5th percentile), indicating no observed weaponization yet despite the 9.8 CVSS rating.
Use-after-free in the WebRTC Audio/Video component of Mozilla Firefox allows a remote attacker to corrupt memory and potentially achieve arbitrary code execution when a victim visits a malicious page or joins a crafted WebRTC session. All Firefox builds prior to 153 and ESR builds prior to 140.13 are affected, with high impact to confidentiality, integrity and availability. There is no public exploit identified at time of analysis and the EPSS probability is low (0.15%), but browser memory-corruption bugs of this class are historically attractive exploitation targets.
Memory corruption in the cubeb audio/video library used by Mozilla Firefox arises from incorrect boundary conditions (CWE-119), and Mozilla fixed it in Firefox 153, Firefox ESR 115.38, and Firefox ESR 140.13 (advisories MFSA2026-68/69/70). The input CVSS rates it 9.8 (network, no privileges, no user interaction), implying an unauthenticated remote attacker could corrupt memory in the browser and potentially achieve code execution, though as a media-processing flaw real exploitation almost certainly requires a victim to render attacker-controlled audio/video content. There is no public exploit identified at time of analysis and EPSS is low (0.15%, 5th percentile), and it is not in CISA KEV.
Same-origin policy bypass in Mozilla Firefox's DOM: Navigation component allows a malicious web page to read or manipulate content belonging to another origin, defeating the browser's core cross-origin isolation boundary. All Firefox users on affected pre-153 releases and unpatched ESR branches are exposed, and while Mozilla's vector maps to CVSS 9.8, EPSS estimates only a 0.16% exploitation probability (6th percentile). There is no public exploit identified at time of analysis and it is not in CISA KEV.
Stack-based buffer overflow in libssh's SFTP server allows a connected client to crash the server or potentially execute code by placing files with overlong names into a directory the server subsequently lists. The flaw lives in how libssh builds the SFTP 'longname' field, concatenating attacker-influenced filenames into a fixed-size stack buffer without adequate bounds checking. There is no public exploit identified at time of analysis and EPSS is very low (0.10%), but the memory-corruption nature (CWE-121) and libssh's broad deployment make it worth prioritized patching.
Compression-amplification denial of service in the Netty network framework (versions prior to 4.1.136.Final and 4.2.16.Final) allows a remote peer to send a small zlib-compressed SPDY HEADERS block that Netty keeps inflating even after the raw header parser exceeds maxHeaderSize and marks the frame truncated in SpdyFrameCodec. The result is disproportionate CPU consumption and allocation churn (CWE-400) from a tiny input, degrading or crashing services that expose the SPDY codec. No public exploit identified at time of analysis and it is not listed in CISA KEV; impact is availability-only per CVSS 7.5 (A:H).
Memory-amplification denial of service in the Netty network framework (SPDY/3.1 codec) prior to 4.1.136.Final and 4.2.16.Final allows a remote unauthenticated peer to send a single ~2 MiB SPDY SETTINGS frame that forces the server to materialize 262,144 map entries in DefaultSpdySettingsFrame, driving heap growth and ordered-map insertion CPU cost far out of proportion to the input. Affected are Java services that enable Netty's SPDY handler and accept untrusted connections; there is no public exploit identified at time of analysis, and while CVSS is 7.5 the low EPSS-style real-world footprint is tempered by SPDY/3.1 being a deprecated, rarely-enabled protocol.
Command-restriction bypass in Apache MINA SSHD (server-side) lets a user who authenticates with an OpenSSH user certificate carrying a force-command directive execute arbitrary commands instead of the single restricted command the certificate authority intended. The server accepts and honors such certificates but silently ignores the force-command and verify-required options, breaking the security model that certificate issuers rely on to constrain principals. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the flaw is confirmed and fixed by the Apache Software Foundation in versions 2.19.0 and 3.0.0-M5.
Eval-based command injection in the Net::DNS module for Perl (versions through 1.55) lets a malicious or man-in-the-middle DNS server run arbitrary shell commands on a client that parses an EDNS EXTENDED-ERROR option. The EXTRA-TEXT field is tokenised and passed to Perl's eval with escaping for $ and @ but not backticks, so a crafted response reaching option('EXTENDED-ERROR') in array context executes attacker-supplied commands. Rated CVSS 9.8; no public exploit identified at time of analysis, though the advisory publishes a working {0:`"<command>"`} payload, EPSS is low at 0.41%, and it is not in CISA KEV.
SQL injection in syslog-ng versions before 4.12 (also fixed in Premium Edition 8.2 and Store Box 7.8) allows an attacker who controls an untrusted log source to inject SQL through log data processed by the afsql SQL destination driver, because afsql_dd_run_query omits a required sanitization call. Exploitation only affects deployments that have manually configured the SQL driver, and there is no public exploit identified at time of analysis and no CISA KEV listing. The rated impact centers on integrity of the backing database and availability of the logging pipeline (CVSS 7.1).
Arbitrary file write in pulpcore's FilesystemExport feature allows an authenticated administrator to escape the intended export directory via directory-traversal sequences embedded in a user-controlled relative_path. Because the exported file content is also attacker-supplied (an uploaded artifact), the flaw lets a privileged user plant or overwrite arbitrary files anywhere the Pulp service user can write, enabling service compromise or broader host takeover. Rated CVSS 9.0 and reported by Red Hat, it affects pulpcore as embedded in Ansible Automation Platform 2, Satellite 6, and Red Hat Update Infrastructure 4/5; there is no public exploit identified at time of analysis.
Out-of-bounds read in the Linux kernel's AMD IOMMU debugfs subsystem exposes local users with standard privileges to potential kernel memory disclosure or denial of service via a sign-extension defect. The functions iommu_mmio_write() and iommu_capability_write() declare offset variables as signed int but populate them with kstrtou32_from_user(), allowing values in the range 0x80000000-0xFFFFFFFF to wrap negative and theoretically index before the intended MMIO region. The vulnerability description explicitly characterizes it as latent, acknowledging that three pre-existing defensive layers already prevent exploitation in practice; the fix replaces the unsigned parser with kstrtos32_from_user() and adds explicit negativity checks. No public exploit exists, no KEV listing is present, and EPSS sits at 0.15% (5th percentile).
Memory leak in the Linux kernel's wilc1000 WiFi driver exposes systems with Microchip WILC1000 adapters to kernel heap exhaustion. The function wilc_wlan_firmware_download() allocates a DMA buffer via kmalloc() but an early-return path after the first acquire_bus() call bypasses the established cleanup label, leaking the buffer unconditionally on bus acquire failures. No public exploit has been identified and EPSS probability is extremely low (0.17%, 6th percentile), but repeated triggering on affected embedded hardware could degrade system stability. Upstream stable fixes are available as confirmed kernel commits targeting 6.18.x, 7.0.x, and 7.1.
Slab out-of-bounds read in the Linux kernel IFB (Intermediate Functional Block) network driver exposes adjacent kernel memory and risks system instability when a local user with low privileges queries ethtool statistics on an asymmetrically configured IFB device. The root cause is a queue-count mismatch: ethtool stat callbacks size and walk per-queue data using real_num_rx_queues and real_num_tx_queues, while the underlying tx_private allocation is sized only to num_tx_queues - creating an over-read when RX queue count exceeds TX queue count. No public exploit has been identified at time of analysis, and EPSS sits at 0.17% (7th percentile), though patch availability across multiple stable branches confirms vendor acknowledgment and active remediation.
Use-after-free in the Linux kernel ISCI (Intel SAS) driver's device removal path allows a local attacker with low privileges to corrupt kernel memory by racing the completion tasklet against driver teardown, potentially enabling privilege escalation. Systems running affected kernel versions with Intel ISCI SAS hardware are vulnerable across multiple stable branches, with vendor-released fixes available in 5.10.258, 5.15.209, 6.1.175, 6.6.142, 6.12.92, 6.18.34, 7.0.11, and 7.1. No public exploit has been identified and EPSS of 0.18% (7th percentile) confirms no observed widespread exploitation, though the KASAN-verified reproduction documented in the fix commit confirms the failure class is reliably triggerable under controlled conditions.
Out-of-bounds heap write in the Linux kernel's ADM1266 PMBus power-sequencer hwmon driver allows a locally-privileged attacker - aided by a malicious or non-compliant ADM1266 device - to overflow kernel heap memory by up to 191 bytes, potentially achieving privilege escalation or kernel code execution. The root cause is a size-contract violation between adm1266_pmbus_block_xfer() (which trusts device-supplied lengths up to 255 bytes) and adm1266_nvmem_read_blackbox() (which allocates only 64-byte strides). No public exploit code has been identified at time of analysis; EPSS is 0.18%, consistent with low in-the-wild interest.
Use-after-free in the Linux kernel's fprobe subsystem exposes kernel memory to corruption when a fprobe is released immediately after unregistration without waiting for an RCU grace period. The flaw was introduced by commit 4346ba1604093, which rewrote fprobe on the function-graph tracer and placed struct fprobe on an RCU-protected hlist but omitted the required synchronize_rcu() call in unregister_fprobe(), leaving a window where in-flight RCU readers may dereference freed memory. BPF users of fprobe are explicitly unaffected because BPF defers deallocation through the bpf_link_defer_dealloc_rcu_gp() RCU callback; affected paths are fprobe events and sample module code.
Use-after-free (CWE-416) in the Linux kernel nvme-pci driver allows a local attacker or triggerable hardware condition to crash the kernel or potentially corrupt memory. The nvme_free_host_mem() function frees dev->hmb_sgt but never clears the pointer, so a double-call during an error path in nvme_probe() dereferences the freed and zeroed DMA structure, causing a NULL pointer dereference in iommu_dma_free_noncontiguous(). Observed reliably on Thunderbolt-attached NVMe devices with PCIe link instability; no public exploit or active exploitation identified at time of analysis.
Memory corruption in the Linux kernel netfs subsystem allows local authenticated users to corrupt kernel heap state via a crafted sequence of streaming write operations on network-backed filesystems, potentially enabling local privilege escalation to root. The bug resides in netfs_perform_write(): when a subsequent write fully overwrites a partially-dirty streaming-write folio, the netfs_folio struct that tracks the dirty byte region is neither freed nor correctly updated, leaving stale or inconsistent metadata that drives out-of-bounds writes (CWE-787) during later writeback processing. Patched versions are available across all active stable branches (6.12.92, 7.0.11, 7.1, 6.18.34); no public exploit or active exploitation has been identified at time of analysis.
Double-free memory corruption in the Linux kernel's net/shaper subsystem allows a local attacker with CAP_NET_ADMIN capability to corrupt the kernel heap by submitting a crafted GROUP netlink request containing duplicate leaf handles. Affected kernels span from the introduction of the net shaper subsystem (~6.13) through multiple stable branches, with fixes backported to 6.18.34, 7.0.11, and 7.1. No public exploit or active exploitation has been identified; vendor-released patches are available via kernel.org and distribution advisories such as Ubuntu USN-8593-1.
Host-based policy bypass in the fast-uri Node.js URI parser (versions 2.3.1 through 4.1.0, spanning the 2.x line up to 2.4.2 and the 3.x line up to 3.1.3) allows remote attackers to smuggle a different host past allowlist, denylist, SSRF, loopback, and redirect-validation checks by using a literal backslash. Because fast-uri does not treat U+005C as an authority delimiter while Node's native WHATWG URL parser (used by fetch, undici, and the http/https clients) normalizes backslash to forward slash for special schemes, the two parsers disagree on the host, enabling requests to be steered to cloud metadata, loopback, or internal endpoints. There is no public exploit identified at time of analysis, but the flaw is trivially triggerable in affected deployments and openjsf has published a fix.
Local privilege escalation and memory corruption in the Linux kernel amdgpu driver stems from VCN (Video Core Next) v2.5 encoder/decoder rings accepting command-stream submissions that request 64-bit user fence writes, an operation the hardware does not support. A local user with render-node access to an AMD GPU can submit a crafted CS with a user fence, causing the kernel to write to an unsupported/attacker-influenced fence address. No public exploit is identified at time of analysis; EPSS is low (0.16%, 5th percentile) and the flaw is not in CISA KEV.
Unauthenticated remote denial of service in the JLine3 remote-telnet server module (versions before 3.30.14, 4.0.16, and 4.2.1) lets an attacker crash the JVM by flooding the Telnet NEW-ENVIRON negotiation with unbounded unique environment-variable pairs. Because TelnetIO.readNEVariables() stores every pair in an uncapped HashMap on ConnectionData before login, roughly 3-4 MB of traffic can exhaust a 512 MB heap and force an OutOfMemoryError. No public exploit code is identified, but the vendor advisory (GHSA-47qp-hqvx-6r3f) documents proof-of-concept methodology; the flaw is not listed in CISA KEV and no EPSS score was supplied.
Denial of service in the JLine3 Telnet server (jline-remote-telnet module) lets an unauthenticated remote attacker exhaust server CPU by abusing the Telnet NAWS window-size option. Because TelnetIO enforces only a lower bound on terminal dimensions, a client can advertise a 65535x65535 terminal and repeatedly alternate values to force continuous, expensive redisplay/rendering cycles. Publicly available exploit code exists (a raw two-packet Telnet PoC is published in the vendor GHSA advisory), and there is no public exploit identified as being actively exploited; the issue is fixed in 3.30.14, 4.0.16, and 4.2.1.
Privilege escalation via incomplete privilege drop in the Python 'sh' subprocess library (versions < 2.2.4): when a root/privileged process launches a command with the _uid option, the child changes UID and primary GID but fails to clear the parent's supplementary groups via setgroups(). Any subprocess expected to run unprivileged can therefore retain sensitive parent groups (root, docker, disk, shadow, sudo), reading or writing resources those groups grant. No public exploit identified at time of analysis and it is not in CISA KEV; the fix is confirmed in release 2.2.4.
Memory-disclosure via heap buffer overflow in libjxl (the JPEG XL reference codec) versions 0.11.2 and earlier lets an attacker who supplies a crafted APNG image trigger an out-of-bounds access in the DecodeImageAPNG function, leaking sensitive process memory. The upstream fix (PR #4804) adds a missing row-index bounds check before accessing frame rows. No public exploit identified at time of analysis; EPSS is low (0.15%, 5th percentile) and the issue is not listed in CISA KEV.
Out-of-bounds heap read in YAML::Syck before 1.47 for Perl lets an attacker who controls a parsed YAML document trigger a one-byte over-read in the bundled libsyck lexer, with a total (per SSVC) technical impact of information disclosure or process crash. The flaw sits in newline_len/is_newline, which dereference the scan pointer (and the following byte for a "\r\n" pair) with no NUL-terminator or bounds check, so a block scalar sitting at a document boundary runs one byte past the heap lexer buffer. There is no public exploit identified at time of analysis and it is not in CISA KEV, but CPANSec-documented trigger inputs exist and it is explicitly an incomplete fix of CVE-2025-11683 on a lexer path the earlier patch missed.
Heap use-after-free in YAML::Syck for Perl before version 1.47 lets a crafted YAML document corrupt parser memory when it redefines a previously declared anchor. The bug lives in the bundled libsyck C code (syck_hdlr_add_anchor), where an anchor name string is shared between a node's node->anchor field and the parser's anchors-table key; freeing the node frees the shared key, and a subsequent anchor redefinition makes st_delete/st_strcmp compare against freed heap memory. Any Perl application that calls Load or LoadFile on untrusted YAML is affected on the default code path (anchors need no special flags). Reported by CPANSec and disclosed via oss-security; publicly documented proof-of-concept trigger inputs exist, but there is no CISA KEV listing and no evidence of active exploitation.
Out-of-bounds read in the Perl module YAML::Syck before 1.47 lets a remote attacker leak adjacent process memory by feeding a crafted YAML document to Load or LoadFile. The bundled libsyck base64 decoder (syck_base64dec) indexes its 256-entry b64_xtable with a signed char, so any !!binary byte >= 0x80 sign-extends to a negative index and reads before the table; because !!binary is a standard tag processed on the default Load path (not gated by $LoadBlessed or $LoadCode), the flaw is reachable without any opt-in. No CISA KEV listing and EPSS is low (0.19%, 8th percentile), so no public weaponized exploit is identified at time of analysis, though the exact trigger strings (e.g. '--- !!binary \x80\x80\x80\x80') are publicly documented in the vendor's CI test suite and the oss-security advisory.
Remote denial of service in CoreDNS versions prior to 1.14.4 allows an unauthenticated attacker to crash the DNS server with a single 28-byte UDP datagram when the proxyproto plugin is enabled. The malformed PROXY protocol v2 header triggers a nil pointer dereference in the PacketConn.ReadFrom log path, killing the process before per-request recovery can intervene. No public exploit identified at time of analysis, though the fixing PR includes a reproducer test that encodes the exact crashing byte sequence; not listed in CISA KEV.
Improper TLS hostname verification in the Snowflake Connector for Python (versions before 4.7.1) lets an on-path attacker defeat HTTPS certificate validation, accepting any certificate signed by any trusted CA regardless of the requested hostname. An adversary who can intercept traffic can decrypt and tamper with connector sessions, exposing Snowflake credentials, query results, and staged file data, and can inject arbitrary SQL bounded by the victim role's privileges. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the reporting vendor (Snowflake) rates it CVSS 4.0 9.2.
Uncontrolled memory allocation in Grafana Loki lets remote unauthenticated users issue queries with excessively large limit values, forcing the service to allocate large amounts of memory and potentially exhausting host resources. The impact is denial of service (CVSS 7.5, A:H only) and varies by deployment topology - a single-binary or under-provisioned deployment is far more exposed than a horizontally scaled microservices setup. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; note the input 'Information Disclosure' tag conflicts with the CVSS impact (C:N/I:N/A:H), which indicates an availability-only issue.
Remote denial of service in Datadog's dd-trace-go APM library lets unauthenticated attackers exhaust CPU and memory on any instrumented HTTP service by sending an oversized W3C 'baggage' header. The DD_TRACE_BAGGAGE_MAX_ITEMS (64) and DD_TRACE_BAGGAGE_MAX_BYTES (8192) safety limits were enforced only on baggage injection, not extraction, so a single crafted request with a huge number of comma-separated key-value pairs forces one hash-map allocation per pair on every request. Because baggage propagation is enabled by default, any internet-facing Go service using an affected tracer is exposed; there is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in Red Hat OpenShift GitOps (Argo CD operator) lets a tenant who controls a namespace-scoped Argo CD instance delete a ClusterRole belonging to a cluster-scoped Argo CD instance by crafting a name collision. Because the ClusterRole reconciler skips ownership validation (CWE-862), a low-privileged tenant can disrupt a higher-privileged, cluster-wide GitOps instance across the trust boundary. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the cross-tenant scope change makes it a meaningful multi-tenancy integrity concern.
Command injection in LiteLLM 1.18.10 lets attackers who can configure MCP (Model Context Protocol) servers supply arbitrary `command` and `args` values in the server-creation JSON, which LiteLLM passes to the host OS without validation, yielding remote code execution as the LiteLLM process. The flaw is part of the broader MCP-stdio supply-chain advisory disclosed by ox.security across the AI ecosystem and is documented in LiteLLM's own April 2026 advisory. No public exploit is identified in the provided data, and EPSS is low (0.32%, 24th percentile), so widespread automated exploitation is not currently indicated despite the CVSS 9.8 rating.
Arbitrary file write via symlink traversal in Rclone prior to 1.74.4 lets an attacker-controlled remote escape the local sync destination when a victim runs a copy/sync with the -l/--links flag. Rclone stores symlinks as .rclonelink text objects and recreates them on the local target without validating the link target, so a malicious remote can plant an escaping symlink and have a subsequent object write land outside the chosen destination with attacker-chosen contents. Publicly available exploit code exists (GHSA PoC), but there is no evidence of active exploitation and EPSS is low (0.34%).
Denial of service in the Netty netty-codec-stomp module (versions 4.1.x up to 4.1.135.Final and 4.2.0.Alpha1 through 4.2.15.Final) allows a remote attacker to trigger an OutOfMemoryError and crash the JVM. The StompSubframeDecoder caps individual header line length via maxLineLength but never bounds the total header count or cumulative header size, so a single STOMP frame packed with thousands of short headers exhausts heap memory. Publicly available exploit code exists (a working client/server PoC is published in the GitHub Security Advisory), but there is no public evidence of active exploitation; EPSS/KEV signals are not present in the input.
Use-after-free in Google Chrome's UI component on Linux (versions prior to 150.0.7871.125) lets a remote attacker trigger heap corruption through a crafted HTML page, but only after luring the victim into performing specific UI gestures. Rated High severity by Chromium and CVSS 7.5, the flaw carries full confidentiality, integrity, and availability impact and could lead to code execution inside the renderer, though no public exploit identified at time of analysis and SSVC records exploitation status as none. EPSS is low (0.29%, 21st percentile), consistent with the high attack complexity and required user interaction.
Remote code execution in Google Chrome's V8 JavaScript engine (versions prior to 150.0.7871.125) allows a remote attacker to run arbitrary code within the renderer sandbox when a victim visits a crafted HTML page. Rated High by Chromium and CVSS 8.8, the flaw is a type-confusion class issue in V8 requiring only that the user browse to attacker-controlled content. There is no public exploit identified at time of analysis and EPSS is low (0.34%), but Chrome's ubiquity and the total technical impact make patching urgent.
Sandbox escape in Google Chrome desktop and ChromeOS builds prior to 150.0.7871.125 stems from a use-after-free in the Skia graphics library, allowing a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a crafted HTML page. Google rates this High severity; SSVC technical impact is 'total' with a scope change (S:C), but exploitation is not observed (no public exploit identified at time of analysis) and EPSS is low at 0.24%. A vendor patch is available.
Sandbox escape in Google Chrome on Windows (versions prior to 150.0.7871.125) stems from a use-after-free in the browser's Core component, letting a remote attacker who lures a user to a crafted HTML page corrupt memory and potentially break out of the renderer sandbox. The flaw is rated High by Chromium and carries a 9.6 CVSS due to scope change and full CIA impact, though it requires user interaction (visiting the page). There is no public exploit identified at time of analysis, and CISA's SSVC framework marks exploitation as none, with a low EPSS probability of 0.26%.
Sandbox escape in Google Chrome for Android (versions prior to 150.0.7871.125) stems from a use-after-free in the GPU process, allowing an attacker who has already compromised the renderer to break out of the browser sandbox via a crafted HTML page. Rated High by Chromium with a CVSS of 8.3, it carries a scope-changing, total-impact profile but is gated by prior renderer compromise, and there is no public exploit identified at time of analysis. EPSS is low (0.24%, 16th percentile) and CISA SSVC records exploitation status as none.
Sandbox escape in Google Chrome on Linux prior to 150.0.7871.125 allows an attacker who has already compromised the renderer process to break out of the sandbox via a crafted HTML page, chaining from renderer compromise to broader host access. The flaw resides in the Linux Toolkit Theming component (CWE-20, insufficient input validation) and is rated High by Chromium with a CVSS of 8.3. There is no public exploit identified at time of analysis, EPSS is low (0.26%), and CISA SSVC lists exploitation status as none, so this is a defense-in-depth-critical but not currently exploited issue.
Renderer-side arbitrary code execution in Google Chrome for Windows (versions prior to 150.0.7871.125) stems from a heap buffer overflow in the bundled libyuv video color-conversion library, letting a remote attacker who lures a victim into loading a crafted video file run code within the renderer sandbox. Chromium rates the severity High; the flaw was reported internally by the Chrome team and a fixed stable build is available. There is no public exploit identified at time of analysis, and EPSS is low (0.33%, 25th percentile), consistent with SSVC exploitation status 'none'.
Heap corruption in Google Chrome's Ozone graphics/windowing layer (versions prior to 150.0.7871.125) lets a remote attacker who lures a victim to a crafted HTML page and coaxes them into specific UI gestures trigger a use-after-free with total technical impact. Chromium rates the underlying bug Critical, though the CVSS is 7.5 because exploitation hinges on user interaction and high attack complexity. There is no public exploit identified at time of analysis, EPSS risk is low (0.30%, 22nd percentile), and CISA SSVC records exploitation status as none.
Heap corruption in Google Chrome's Ozone component on Linux (versions prior to 150.0.7871.125) allows a remote attacker to potentially execute arbitrary code within the browser process after luring a victim to a crafted HTML page and coaxing them into specific UI gestures. Chromium rated the flaw Critical severity, though its practical exploitability is tempered by the required user interaction and high attack complexity. There is no public exploit identified at time of analysis, and CISA's SSVC framework records exploitation status as 'none'.
Network denial of service in Microsoft .NET 8.0, 9.0, and 10.0 (and the corresponding Visual Studio 2022/2026 tooling) allows an unauthorized remote attacker to exhaust system resources and render affected applications unavailable. The flaw stems from allocation of resources without limits or throttling, meaning a single crafted network interaction can trigger disproportionate resource consumption. Reported by Microsoft with a vendor patch available; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Memory corruption via integer overflow in Mozilla Firefox's ImageLib graphics component allows remote attackers to potentially achieve code execution by serving a maliciously crafted image, with the flaw resolved in Firefox 153. The CVSS 9.8 rating reflects unauthenticated network reach with high impact to confidentiality, integrity, and availability, though no public exploit has been identified and the EPSS probability of 0.13% (3rd percentile) indicates no observed exploitation activity to date. It is not listed in CISA KEV and there is no public exploit identified at time of analysis.
Privilege escalation in Mozilla Firefox's Data Loss Prevention (DLP) component allows an attacker to gain elevated privileges beyond those intended for the affected process or policy context, with all confidentiality, integrity, and availability impacts rated high. Mozilla assigned a CVSS base score of 9.8, though the network/unauthenticated vector conflicts with the 'privilege escalation' framing typical of local flaws. There is no public exploit identified at time of analysis, and EPSS estimates only a 0.13% exploitation probability (3rd percentile), indicating low near-term real-world weaponization despite the high CVSS.
Information disclosure in Mozilla Firefox's DOM: Security component allows remote attackers to read sensitive cross-origin or in-process data via crafted web content, undermining the browser's same-origin and security boundary enforcement. Any Firefox version prior to 153 is affected, and exploitation is remote and unauthenticated with no user interaction beyond visiting a malicious page. The issue was reported and fixed by Mozilla; no public exploit identified at time of analysis and EPSS exploitation probability is low (0.13%).
Cross-origin information disclosure in Mozilla Firefox's DOM: Navigation component allows a malicious web page to bypass site isolation (Fission) boundaries and read data belonging to another origin. The flaw affects Firefox versions prior to 153 and is remotely reachable over the network with no privileges required, though impact is limited to confidentiality. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.13%).
Information disclosure in Mozilla Firefox before version 153 stems from a site isolation weakness in the Graphics component, allowing a remote attacker to read cross-origin data that should be siloed between sites. The confidentiality-only flaw (CVSS 7.5, C:H) is network-reachable without authentication or user interaction, but carries no public exploit and a low EPSS score (0.13%, 3rd percentile), indicating theoretical rather than active risk. It is not listed in CISA KEV; no public exploit identified at time of analysis.
Privilege escalation in the WebExtensions subsystem of Mozilla Firefox lets a WebExtension gain capabilities beyond its granted permission set, corresponding to CWE-269 (Improper Privilege Management). Mozilla, the reporting vendor, fixed the issue in Firefox 153 and Firefox ESR 140.13 (advisories MFSA2026-68/70/71/72). No public exploit has been identified at time of analysis and the EPSS probability is low at 0.14% (4th percentile), despite the vendor-supplied 9.8 CVSS score.
Memory-corruption via an integer overflow in Mozilla Firefox's Audio/Video component allows remote attackers to compromise the browser when a victim processes attacker-controlled media, with the CVSS 9.8 vector (AV:N/AC:L/PR:N/UI:N) indicating unauthenticated network exploitation and high impact to confidentiality, integrity, and availability. The flaw was fixed in Firefox 153 per Mozilla advisory MFSA2026-68. There is no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
Protection mechanism failure in the DOM: Security component of Mozilla Firefox lets remote attackers bypass a browser security mitigation, undermining defenses that isolate web content and enforce origin/policy boundaries. Mozilla rates this Critical (CVSS 9.1) with high confidentiality and integrity impact and no authentication or user interaction required per the assigned vector; it is corrected in Firefox 153 (MFSA 2026-68). There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Memory corruption in the Audio/Video Gecko Media Plugin (GMP) component of Mozilla Firefox lets remote attackers trigger a buffer overflow through crafted media content, which per CVSS can disclose sensitive process memory and corrupt process state (C:H/I:H). The flaw affects Firefox before 153 and the ESR 115.x and 140.x branches; Mozilla shipped fixes in Firefox 153, ESR 115.38, and ESR 140.13. There is no public exploit identified at time of analysis and it is not in CISA KEV, but the 9.1 CVSS reflects an unauthenticated, network-reachable memory-safety bug in a core browser subsystem.
Memory corruption in Mozilla Firefox's WebGPU graphics component (fixed in Firefox 153) lets a remote attacker serving crafted web content trigger an out-of-bounds memory operation, enabling sensitive memory disclosure and browser crashes. The flaw is a CWE-119 boundary-condition error rated CVSS 9.1 (C:H/A:H, no integrity impact), consistent with an information-leak-plus-denial-of-service primitive rather than confirmed code execution. No public exploit identified at time of analysis, and EPSS is low (0.13%, 3rd percentile), indicating no evidence of active exploitation despite the high base score.
Information disclosure in Mozilla Firefox's Storage: IndexedDB component allows a remote attacker to leak sensitive data across origins or from other browsing contexts without authentication or user interaction. The flaw affects Firefox releases prior to 153 and ESR builds prior to 140.13; there is no public exploit identified at time of analysis, and its EPSS score (0.15%, 5th percentile) indicates low near-term exploitation likelihood despite a CVSS of 7.5. Mozilla has released fixed builds, so the practical priority is prompt browser updating rather than emergency response.
Protection-mechanism bypass in Mozilla Firefox's Enterprise Policies component allows attackers to circumvent security restrictions that administrators enforce through managed policy, undermining controls an organization relies on to lock down the browser. Mozilla rates the flaw CVSS 9.1 (network vector, low complexity, no privileges or user interaction) affecting Firefox before 153 and Firefox ESR before 140.13. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.16%, 6th percentile).
Sandbox escape in Mozilla Firefox's DOM: Networking component allows a remote attacker to break out of the content-process security boundary, fixed in Firefox 153. Rated CVSS 9.8, it maps to CWE-693 (Protection Mechanism Failure) and is tagged as an information-disclosure issue by Mozilla, meaning a compromised or malicious web page could bypass the browser's isolation to reach host resources. No public exploit identified at time of analysis, and the EPSS score is low (0.14%, 4th percentile), indicating no observed exploitation activity yet.
Information disclosure in Mozilla Firefox and Firefox ESR stems from a site isolation flaw in the Networking component, letting a malicious web page bypass cross-origin process/security boundaries and access data belonging to other sites. The issue was reported by Mozilla and fixed in Firefox 153 and Firefox ESR 140.13; no public exploit identified at time of analysis, and EPSS exploitation probability is low at 0.15% (5th percentile).
Information disclosure in Mozilla Firefox's Graphics WebGPU component allows a malicious web page to read uninitialized process memory, potentially leaking sensitive data such as heap contents, pointers, or cross-origin material, before the fix in Firefox 153. The flaw stems from WebGPU operating on memory that was never initialized (CWE-908), and while CVSS rates confidentiality impact High (7.5), EPSS is very low (0.14%, 4th percentile) with no public exploit and no CISA KEV listing. Exploitation is browser-based, requiring a victim to load attacker-controlled WebGPU content.
Information disclosure in Mozilla Firefox's Graphics WebGPU component allows a remote attacker to read leftover uninitialized memory, potentially exposing sensitive data such as other pages' content, GPU buffers, or process memory. The flaw stems from a WebGPU code path returning memory that was never zeroed, and is fixed in Firefox 153; there is no public exploit identified at time of analysis and the EPSS score is low (0.14%, 4th percentile).
Information disclosure in Mozilla Firefox's Graphics: WebGPU component allows remote attackers to read uninitialized memory contents via crafted WebGPU operations, potentially leaking sensitive process memory such as heap data, addresses, or other page content. The flaw is network-reachable without authentication or user interaction beyond visiting a malicious page, but carries no integrity or availability impact. There is no public exploit identified at time of analysis, and EPSS estimates a low 0.14% exploitation probability.
Security-mitigation bypass in Mozilla Firefox's DOM: Networking component undermines a built-in protection mechanism (CWE-693), potentially allowing crafted web content to defeat network-layer defenses in versions prior to Firefox 153 and ESR 140.13. The issue was reported and patched by Mozilla with no public exploit identified at time of analysis; EPSS is very low (0.16%, 6th percentile) and it is not listed in CISA KEV. The NVD-assigned CVSS of 9.8 (network, no auth, no user interaction) sits in tension with the sparse 'mitigation bypass' description, which typically describes a defense-defeating enabler rather than direct code execution.
Protection-mechanism bypass in Mozilla Firefox's DOM Service Workers component allows remote web content to circumvent a browser security mitigation, weakening defenses that normally contain untrusted script. The flaw affects Firefox versions prior to 153 and was reported and patched by Mozilla (MFSA2026-68). No public exploit has been identified at time of analysis, and EPSS estimates exploitation probability at only 0.15% (5th percentile), indicating no observed weaponization despite the high nominal CVSS score.
Same-origin policy bypass in Mozilla Firefox's Networking DNS component allows remote attackers to circumvent origin isolation and read or manipulate data belonging to other web origins. Affects Firefox before 153 and Firefox ESR before 140.13, exploitable over the network without authentication or user interaction (CVSS 9.1). No public exploit identified at time of analysis; EPSS is low (0.16%, 6th percentile).
Protection mechanism bypass in the Networking component of Mozilla Firefox (versions prior to 153) allows remote attackers to circumvent a built-in security mitigation over the network without authentication or user interaction, per the CVSS vector (AV:N/AC:L/PR:N/UI:N). Mozilla (MFSA2026-68) tags this as an authentication/mitigation bypass with high confidentiality and integrity impact but no availability impact. No public exploit identified at time of analysis, and EPSS exploitation probability is low at 0.15% (5th percentile).
Cross-origin information disclosure in Mozilla Firefox arises from a site isolation weakness in the Graphics: WebRender rendering component, where origin boundaries are not correctly enforced during GPU-accelerated compositing. An attacker-controlled web page loaded by a victim could leak data belonging to a different origin, undermining the same-origin protections that site isolation is meant to guarantee. Mozilla fixed the issue in Firefox 153, Firefox ESR 115.38, and Firefox ESR 140.13; there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.15%, 5th percentile).
Privilege escalation in Mozilla Firefox's DOM Content Processes component allows an attacker who influences a sandboxed content process to break out of the renderer sandbox and gain elevated privileges on the host, affecting Firefox before 153 and Firefox ESR before 140.13. Mozilla assigns a critical CVSS of 9.8, though the 'content process' scope suggests the practical entry point is attacker-controlled web content rather than a fully unauthenticated network service. No public exploit is identified at time of analysis, and the EPSS exploitation probability is very low (0.15%, 5th percentile).
Information disclosure in Mozilla Firefox before version 153 stems from an input-validation flaw in the DOM Copy & Paste and Drag & Drop component, allowing remote content to potentially read data that should remain isolated. The provided CVSS vector rates confidentiality impact as High with no privileges or user interaction, and Mozilla has shipped a fix in Firefox 153. There is no public exploit identified at time of analysis, and the EPSS score of 0.14% (4th percentile) indicates low near-term exploitation likelihood.
Mitigation bypass in the Mozilla Firefox PDF Viewer component undermines a built-in security control (CWE-693 Protection Mechanism Failure), weakening a defense-in-depth barrier that would otherwise contain malicious PDF content. Mozilla self-reported the issue and shipped fixes in Firefox 153 and Firefox ESR 140.13 via advisories MFSA2026-68 and MFSA2026-70. There is no public exploit identified at time of analysis, and EPSS is very low (0.16%, 6th percentile), so the headline CVSS 9.8 reflects worst-case potential rather than demonstrated mass exploitation.
Remote denial-of-service in Mozilla Firefox's Graphics: WebGPU component allows a malicious web page to exhaust browser resources and crash or hang the browser without any user credentials or interaction. The flaw affects Firefox versions prior to 153 and is triggered simply by loading attacker-controlled content that abuses the WebGPU API. There is no public exploit identified at time of analysis, and EPSS scores the exploitation likelihood at only 0.14%, indicating low near-term probability of widespread exploitation.
Cross-origin information disclosure in Mozilla Firefox and Firefox ESR stems from a site isolation weakness in the Networking: HTTP component (CWE-346, origin validation error), letting a malicious web page bypass origin boundaries to read data belonging to another site. It affects Firefox before version 153 and Firefox ESR before 140.13 and is addressed in Mozilla advisories MFSA2026-68 and MFSA2026-70. There is no public exploit identified at time of analysis, and the EPSS score is low (0.15%, 5th percentile), indicating no observed weaponization despite the vendor's 9.8 CVSS rating.
Information disclosure in the Firefox DevTools Framework component allows an attacker to read data that should remain isolated, affecting Mozilla Firefox prior to 153 and Firefox ESR prior to 140.13. Reported by Mozilla and carrying a CVSS 7.5 (high) rating driven by high confidentiality impact, there is no public exploit identified at time of analysis and the EPSS probability is low at 0.15% (5th percentile). The issue is fixed and not listed in CISA KEV.
Information disclosure in the Privacy component of Mozilla Firefox for Android allows remote attackers to expose sensitive user data, with the flaw carrying a high confidentiality impact (CVSS 7.5). Mozilla self-reported and fixed the issue in Firefox 153 per advisory MFSA2026-68; there is no public exploit identified at time of analysis, and the EPSS probability is low (0.14%, 4th percentile). The Privacy component context suggests leakage of protected browsing state or user data that the browser is designed to isolate.
Privilege escalation in Mozilla Firefox's DOM Content Processes component allows attackers to escape or elevate beyond the sandboxed content process, gaining higher browser privileges on affected versions prior to Firefox 153. The flaw is a CWE-269 improper privilege management issue reported by Mozilla and patched in Firefox 153 (advisory MFSA2026-68). No public exploit has been identified and EPSS is low (0.14%, 4th percentile), indicating no observed exploitation activity at time of analysis despite the high CVSS 9.8 rating.
Protection-mechanism bypass in the DOM: Networking component of Mozilla Firefox lets a remote, unauthenticated attacker circumvent a browser security mitigation, exposing confidential data and enabling integrity compromise (CVSS 9.1) without user interaction. Reported by Mozilla and fixed in Firefox 153, the flaw affects users browsing to attacker-controlled web content. No public exploit identified at time of analysis, and the low EPSS score (0.15%) suggests exploitation is not yet widespread.
Memory corruption in the Graphics component of Mozilla Firefox stems from incorrect boundary conditions (a buffer overflow) that can be triggered when the browser processes maliciously crafted graphics content, potentially leading to arbitrary code execution in the content process. It affects Firefox before 153, Firefox ESR before 115.38, and Firefox ESR before 140.13, and is fixed across those releases per Mozilla advisories MFSA2026-68/69/70. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.15%, 5th percentile) despite the vendor-supplied CVSS of 9.8.
Sandbox escape via use-after-free in Mozilla Firefox's Disability Access (accessibility) APIs allows an attacker who has compromised the content process to break out of the browser sandbox and gain code execution at the host privilege level. It affects Firefox before 153 and the ESR 115.x and 140.x branches, was reported and patched by Mozilla, and carries no public exploit at time of analysis. EPSS is low (0.15%, 5th percentile) and it is not on CISA KEV, indicating no observed exploitation.
Memory corruption in Mozilla Firefox's JavaScript engine JIT compiler allows attackers to corrupt memory and potentially achieve arbitrary code execution when a victim visits a malicious web page. The flaw stems from a JIT miscompilation (type confusion, CWE-843) affecting Firefox before 153, ESR before 115.38, and ESR before 140.13, and carries CVSS 9.8. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.15%, 5th percentile).
Memory corruption in Mozilla Firefox's JavaScript WebAssembly engine, stemming from an integer overflow (CWE-190), can be triggered by attacker-controlled web content and was patched in Firefox 153 and Firefox ESR 140.13. Reported by Mozilla and tracked as EUVD-2026-46202/MFSA2026-68 & MFSA2026-70, the flaw carries a 9.8 CVSS rating implying potential remote code execution, though no public exploit identified at time of analysis and EPSS exploitation probability is low at 0.15% (5th percentile).
Memory corruption in Mozilla Firefox's WebAssembly (JavaScript) engine allows remote attackers to trigger a buffer overflow through incorrect boundary condition handling, potentially leading to arbitrary code execution in the browser content process. The flaw carries a critical CVSS 9.8 and affects Firefox prior to version 153 and Firefox ESR prior to 140.13; it is fixed in those releases per Mozilla advisories MFSA2026-68 and MFSA2026-70. There is no public exploit identified at time of analysis, and the low EPSS score (0.15%) suggests exploitation in the wild has not yet been observed.
Sandbox escape in Mozilla Firefox before version 153 stems from an invalid pointer (CWE-119 memory-safety error) in the Disability Access (accessibility) APIs component, letting an attacker who can execute code in a constrained content process break out of the browser sandbox and reach the more privileged parent process with full confidentiality, integrity, and availability impact (CVSS 10.0, scope-changed). No public exploit identified at time of analysis, and the EPSS probability is low (0.14%, 4th percentile), indicating no evidence of widespread exploitation despite the maximum CVSS score.
Information disclosure in Mozilla Firefox's ImageLib graphics component allows remote attackers to read sensitive data (likely uninitialized or out-of-bounds process memory) when a victim renders attacker-controlled image content, per the CWE-200 classification and the C:H CVSS impact. Affected builds are Firefox before 153 and the ESR 115.x and 140.x branches, all fixed by Mozilla in Firefox 153, ESR 115.38, and ESR 140.13. There is no public exploit identified at time of analysis and EPSS is low (0.15%, 5th percentile), consistent with a vendor-reported browser memory-disclosure issue rather than one under active exploitation.
Memory corruption in Mozilla Firefox's DOM Bindings (WebIDL) layer allows a remote attacker who serves malicious web content to trigger a use-after-free (CWE-416) via an invalid/dangling pointer, potentially leading to arbitrary code execution or information disclosure in the content process. All Firefox and Firefox ESR builds prior to the fixed releases are affected. There is no public exploit identified at time of analysis, and the low EPSS score (0.15%, 5th percentile) suggests exploitation is not yet observed in the wild, though Mozilla rates the memory-safety impact as high.
Privilege escalation in Mozilla Firefox's DOM Navigation component (fixed in Firefox 153) allows an attacker to improperly gain elevated privileges within the browser, per Mozilla advisory MFSA2026-68. The flaw carries a CVSS 9.8 rating claiming full confidentiality, integrity, and availability impact with no privileges or user interaction, though this is atypical for a browser DOM bug. There is no public exploit identified at time of analysis, and EPSS exploitation probability is low (0.14%, 4th percentile).
Memory-corruption in Mozilla Firefox's Audio/Video Playback component allows a remote attacker to achieve confidentiality and integrity compromise (potentially arbitrary code execution) by delivering crafted media content to a victim's browser. Rooted in incorrect boundary conditions (buffer overflow, CWE-119), the flaw affects Firefox versions prior to 153 and carries a CVSS 9.1 rating, though EPSS exploitation probability is low (0.14%, 4th percentile) and no public exploit identified at time of analysis.
Memory-safety corruption in Mozilla Firefox stems from a JIT miscompilation in the JavaScript engine's WebAssembly component, fixed in Firefox 153 and Firefox ESR 140.13. An attacker who lures a victim to a malicious page can supply crafted WebAssembly that the Just-In-Time compiler translates incorrectly, corrupting engine state to disclose memory or achieve code execution in the content process. There is no public exploit identified at time of analysis and the EPSS score is very low (0.15%, 5th percentile), so no active exploitation is indicated despite the 9.8 rating.
Sandbox escape in Mozilla Firefox stems from a use-after-free in the Disability Access (accessibility) APIs, letting an attacker who already controls a sandboxed content process break out of the browser sandbox and compromise the host. It affects Firefox before 153 and the ESR 115.x and 140.x branches, with high impact to confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and the EPSS score is low (0.15%, 5th percentile), indicating no observed widespread exploitation.
Sandbox escape in Mozilla Firefox stems from a use-after-free (CWE-416) in the DOM: Navigation component, letting web-reachable content corrupt memory and cross the content-process sandbox boundary. Affected builds are Firefox before 153, Firefox ESR before 115.38, and Firefox ESR before 140.13; Mozilla self-reported the issue and shipped fixes across all three branches (MFSA-2026-68/69/70). There is no public exploit identified at time of analysis, and EPSS is low (0.15%, 5th percentile), indicating no observed weaponization yet despite the 9.8 CVSS rating.
Use-after-free in the WebRTC Audio/Video component of Mozilla Firefox allows a remote attacker to corrupt memory and potentially achieve arbitrary code execution when a victim visits a malicious page or joins a crafted WebRTC session. All Firefox builds prior to 153 and ESR builds prior to 140.13 are affected, with high impact to confidentiality, integrity and availability. There is no public exploit identified at time of analysis and the EPSS probability is low (0.15%), but browser memory-corruption bugs of this class are historically attractive exploitation targets.
Memory corruption in the cubeb audio/video library used by Mozilla Firefox arises from incorrect boundary conditions (CWE-119), and Mozilla fixed it in Firefox 153, Firefox ESR 115.38, and Firefox ESR 140.13 (advisories MFSA2026-68/69/70). The input CVSS rates it 9.8 (network, no privileges, no user interaction), implying an unauthenticated remote attacker could corrupt memory in the browser and potentially achieve code execution, though as a media-processing flaw real exploitation almost certainly requires a victim to render attacker-controlled audio/video content. There is no public exploit identified at time of analysis and EPSS is low (0.15%, 5th percentile), and it is not in CISA KEV.
Same-origin policy bypass in Mozilla Firefox's DOM: Navigation component allows a malicious web page to read or manipulate content belonging to another origin, defeating the browser's core cross-origin isolation boundary. All Firefox users on affected pre-153 releases and unpatched ESR branches are exposed, and while Mozilla's vector maps to CVSS 9.8, EPSS estimates only a 0.16% exploitation probability (6th percentile). There is no public exploit identified at time of analysis and it is not in CISA KEV.
Stack-based buffer overflow in libssh's SFTP server allows a connected client to crash the server or potentially execute code by placing files with overlong names into a directory the server subsequently lists. The flaw lives in how libssh builds the SFTP 'longname' field, concatenating attacker-influenced filenames into a fixed-size stack buffer without adequate bounds checking. There is no public exploit identified at time of analysis and EPSS is very low (0.10%), but the memory-corruption nature (CWE-121) and libssh's broad deployment make it worth prioritized patching.
Compression-amplification denial of service in the Netty network framework (versions prior to 4.1.136.Final and 4.2.16.Final) allows a remote peer to send a small zlib-compressed SPDY HEADERS block that Netty keeps inflating even after the raw header parser exceeds maxHeaderSize and marks the frame truncated in SpdyFrameCodec. The result is disproportionate CPU consumption and allocation churn (CWE-400) from a tiny input, degrading or crashing services that expose the SPDY codec. No public exploit identified at time of analysis and it is not listed in CISA KEV; impact is availability-only per CVSS 7.5 (A:H).
Memory-amplification denial of service in the Netty network framework (SPDY/3.1 codec) prior to 4.1.136.Final and 4.2.16.Final allows a remote unauthenticated peer to send a single ~2 MiB SPDY SETTINGS frame that forces the server to materialize 262,144 map entries in DefaultSpdySettingsFrame, driving heap growth and ordered-map insertion CPU cost far out of proportion to the input. Affected are Java services that enable Netty's SPDY handler and accept untrusted connections; there is no public exploit identified at time of analysis, and while CVSS is 7.5 the low EPSS-style real-world footprint is tempered by SPDY/3.1 being a deprecated, rarely-enabled protocol.
Command-restriction bypass in Apache MINA SSHD (server-side) lets a user who authenticates with an OpenSSH user certificate carrying a force-command directive execute arbitrary commands instead of the single restricted command the certificate authority intended. The server accepts and honors such certificates but silently ignores the force-command and verify-required options, breaking the security model that certificate issuers rely on to constrain principals. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the flaw is confirmed and fixed by the Apache Software Foundation in versions 2.19.0 and 3.0.0-M5.
Eval-based command injection in the Net::DNS module for Perl (versions through 1.55) lets a malicious or man-in-the-middle DNS server run arbitrary shell commands on a client that parses an EDNS EXTENDED-ERROR option. The EXTRA-TEXT field is tokenised and passed to Perl's eval with escaping for $ and @ but not backticks, so a crafted response reaching option('EXTENDED-ERROR') in array context executes attacker-supplied commands. Rated CVSS 9.8; no public exploit identified at time of analysis, though the advisory publishes a working {0:`"<command>"`} payload, EPSS is low at 0.41%, and it is not in CISA KEV.
SQL injection in syslog-ng versions before 4.12 (also fixed in Premium Edition 8.2 and Store Box 7.8) allows an attacker who controls an untrusted log source to inject SQL through log data processed by the afsql SQL destination driver, because afsql_dd_run_query omits a required sanitization call. Exploitation only affects deployments that have manually configured the SQL driver, and there is no public exploit identified at time of analysis and no CISA KEV listing. The rated impact centers on integrity of the backing database and availability of the logging pipeline (CVSS 7.1).
Arbitrary file write in pulpcore's FilesystemExport feature allows an authenticated administrator to escape the intended export directory via directory-traversal sequences embedded in a user-controlled relative_path. Because the exported file content is also attacker-supplied (an uploaded artifact), the flaw lets a privileged user plant or overwrite arbitrary files anywhere the Pulp service user can write, enabling service compromise or broader host takeover. Rated CVSS 9.0 and reported by Red Hat, it affects pulpcore as embedded in Ansible Automation Platform 2, Satellite 6, and Red Hat Update Infrastructure 4/5; there is no public exploit identified at time of analysis.
Out-of-bounds read in the Linux kernel's AMD IOMMU debugfs subsystem exposes local users with standard privileges to potential kernel memory disclosure or denial of service via a sign-extension defect. The functions iommu_mmio_write() and iommu_capability_write() declare offset variables as signed int but populate them with kstrtou32_from_user(), allowing values in the range 0x80000000-0xFFFFFFFF to wrap negative and theoretically index before the intended MMIO region. The vulnerability description explicitly characterizes it as latent, acknowledging that three pre-existing defensive layers already prevent exploitation in practice; the fix replaces the unsigned parser with kstrtos32_from_user() and adds explicit negativity checks. No public exploit exists, no KEV listing is present, and EPSS sits at 0.15% (5th percentile).
Memory leak in the Linux kernel's wilc1000 WiFi driver exposes systems with Microchip WILC1000 adapters to kernel heap exhaustion. The function wilc_wlan_firmware_download() allocates a DMA buffer via kmalloc() but an early-return path after the first acquire_bus() call bypasses the established cleanup label, leaking the buffer unconditionally on bus acquire failures. No public exploit has been identified and EPSS probability is extremely low (0.17%, 6th percentile), but repeated triggering on affected embedded hardware could degrade system stability. Upstream stable fixes are available as confirmed kernel commits targeting 6.18.x, 7.0.x, and 7.1.
Slab out-of-bounds read in the Linux kernel IFB (Intermediate Functional Block) network driver exposes adjacent kernel memory and risks system instability when a local user with low privileges queries ethtool statistics on an asymmetrically configured IFB device. The root cause is a queue-count mismatch: ethtool stat callbacks size and walk per-queue data using real_num_rx_queues and real_num_tx_queues, while the underlying tx_private allocation is sized only to num_tx_queues - creating an over-read when RX queue count exceeds TX queue count. No public exploit has been identified at time of analysis, and EPSS sits at 0.17% (7th percentile), though patch availability across multiple stable branches confirms vendor acknowledgment and active remediation.
Use-after-free in the Linux kernel ISCI (Intel SAS) driver's device removal path allows a local attacker with low privileges to corrupt kernel memory by racing the completion tasklet against driver teardown, potentially enabling privilege escalation. Systems running affected kernel versions with Intel ISCI SAS hardware are vulnerable across multiple stable branches, with vendor-released fixes available in 5.10.258, 5.15.209, 6.1.175, 6.6.142, 6.12.92, 6.18.34, 7.0.11, and 7.1. No public exploit has been identified and EPSS of 0.18% (7th percentile) confirms no observed widespread exploitation, though the KASAN-verified reproduction documented in the fix commit confirms the failure class is reliably triggerable under controlled conditions.
Out-of-bounds heap write in the Linux kernel's ADM1266 PMBus power-sequencer hwmon driver allows a locally-privileged attacker - aided by a malicious or non-compliant ADM1266 device - to overflow kernel heap memory by up to 191 bytes, potentially achieving privilege escalation or kernel code execution. The root cause is a size-contract violation between adm1266_pmbus_block_xfer() (which trusts device-supplied lengths up to 255 bytes) and adm1266_nvmem_read_blackbox() (which allocates only 64-byte strides). No public exploit code has been identified at time of analysis; EPSS is 0.18%, consistent with low in-the-wild interest.
Use-after-free in the Linux kernel's fprobe subsystem exposes kernel memory to corruption when a fprobe is released immediately after unregistration without waiting for an RCU grace period. The flaw was introduced by commit 4346ba1604093, which rewrote fprobe on the function-graph tracer and placed struct fprobe on an RCU-protected hlist but omitted the required synchronize_rcu() call in unregister_fprobe(), leaving a window where in-flight RCU readers may dereference freed memory. BPF users of fprobe are explicitly unaffected because BPF defers deallocation through the bpf_link_defer_dealloc_rcu_gp() RCU callback; affected paths are fprobe events and sample module code.
Use-after-free (CWE-416) in the Linux kernel nvme-pci driver allows a local attacker or triggerable hardware condition to crash the kernel or potentially corrupt memory. The nvme_free_host_mem() function frees dev->hmb_sgt but never clears the pointer, so a double-call during an error path in nvme_probe() dereferences the freed and zeroed DMA structure, causing a NULL pointer dereference in iommu_dma_free_noncontiguous(). Observed reliably on Thunderbolt-attached NVMe devices with PCIe link instability; no public exploit or active exploitation identified at time of analysis.
Memory corruption in the Linux kernel netfs subsystem allows local authenticated users to corrupt kernel heap state via a crafted sequence of streaming write operations on network-backed filesystems, potentially enabling local privilege escalation to root. The bug resides in netfs_perform_write(): when a subsequent write fully overwrites a partially-dirty streaming-write folio, the netfs_folio struct that tracks the dirty byte region is neither freed nor correctly updated, leaving stale or inconsistent metadata that drives out-of-bounds writes (CWE-787) during later writeback processing. Patched versions are available across all active stable branches (6.12.92, 7.0.11, 7.1, 6.18.34); no public exploit or active exploitation has been identified at time of analysis.
Double-free memory corruption in the Linux kernel's net/shaper subsystem allows a local attacker with CAP_NET_ADMIN capability to corrupt the kernel heap by submitting a crafted GROUP netlink request containing duplicate leaf handles. Affected kernels span from the introduction of the net shaper subsystem (~6.13) through multiple stable branches, with fixes backported to 6.18.34, 7.0.11, and 7.1. No public exploit or active exploitation has been identified; vendor-released patches are available via kernel.org and distribution advisories such as Ubuntu USN-8593-1.
Host-based policy bypass in the fast-uri Node.js URI parser (versions 2.3.1 through 4.1.0, spanning the 2.x line up to 2.4.2 and the 3.x line up to 3.1.3) allows remote attackers to smuggle a different host past allowlist, denylist, SSRF, loopback, and redirect-validation checks by using a literal backslash. Because fast-uri does not treat U+005C as an authority delimiter while Node's native WHATWG URL parser (used by fetch, undici, and the http/https clients) normalizes backslash to forward slash for special schemes, the two parsers disagree on the host, enabling requests to be steered to cloud metadata, loopback, or internal endpoints. There is no public exploit identified at time of analysis, but the flaw is trivially triggerable in affected deployments and openjsf has published a fix.
Local privilege escalation and memory corruption in the Linux kernel amdgpu driver stems from VCN (Video Core Next) v2.5 encoder/decoder rings accepting command-stream submissions that request 64-bit user fence writes, an operation the hardware does not support. A local user with render-node access to an AMD GPU can submit a crafted CS with a user fence, causing the kernel to write to an unsupported/attacker-influenced fence address. No public exploit is identified at time of analysis; EPSS is low (0.16%, 5th percentile) and the flaw is not in CISA KEV.
Unauthenticated remote denial of service in the JLine3 remote-telnet server module (versions before 3.30.14, 4.0.16, and 4.2.1) lets an attacker crash the JVM by flooding the Telnet NEW-ENVIRON negotiation with unbounded unique environment-variable pairs. Because TelnetIO.readNEVariables() stores every pair in an uncapped HashMap on ConnectionData before login, roughly 3-4 MB of traffic can exhaust a 512 MB heap and force an OutOfMemoryError. No public exploit code is identified, but the vendor advisory (GHSA-47qp-hqvx-6r3f) documents proof-of-concept methodology; the flaw is not listed in CISA KEV and no EPSS score was supplied.
Denial of service in the JLine3 Telnet server (jline-remote-telnet module) lets an unauthenticated remote attacker exhaust server CPU by abusing the Telnet NAWS window-size option. Because TelnetIO enforces only a lower bound on terminal dimensions, a client can advertise a 65535x65535 terminal and repeatedly alternate values to force continuous, expensive redisplay/rendering cycles. Publicly available exploit code exists (a raw two-packet Telnet PoC is published in the vendor GHSA advisory), and there is no public exploit identified as being actively exploited; the issue is fixed in 3.30.14, 4.0.16, and 4.2.1.
Privilege escalation via incomplete privilege drop in the Python 'sh' subprocess library (versions < 2.2.4): when a root/privileged process launches a command with the _uid option, the child changes UID and primary GID but fails to clear the parent's supplementary groups via setgroups(). Any subprocess expected to run unprivileged can therefore retain sensitive parent groups (root, docker, disk, shadow, sudo), reading or writing resources those groups grant. No public exploit identified at time of analysis and it is not in CISA KEV; the fix is confirmed in release 2.2.4.
Memory-disclosure via heap buffer overflow in libjxl (the JPEG XL reference codec) versions 0.11.2 and earlier lets an attacker who supplies a crafted APNG image trigger an out-of-bounds access in the DecodeImageAPNG function, leaking sensitive process memory. The upstream fix (PR #4804) adds a missing row-index bounds check before accessing frame rows. No public exploit identified at time of analysis; EPSS is low (0.15%, 5th percentile) and the issue is not listed in CISA KEV.
Out-of-bounds heap read in YAML::Syck before 1.47 for Perl lets an attacker who controls a parsed YAML document trigger a one-byte over-read in the bundled libsyck lexer, with a total (per SSVC) technical impact of information disclosure or process crash. The flaw sits in newline_len/is_newline, which dereference the scan pointer (and the following byte for a "\r\n" pair) with no NUL-terminator or bounds check, so a block scalar sitting at a document boundary runs one byte past the heap lexer buffer. There is no public exploit identified at time of analysis and it is not in CISA KEV, but CPANSec-documented trigger inputs exist and it is explicitly an incomplete fix of CVE-2025-11683 on a lexer path the earlier patch missed.
Heap use-after-free in YAML::Syck for Perl before version 1.47 lets a crafted YAML document corrupt parser memory when it redefines a previously declared anchor. The bug lives in the bundled libsyck C code (syck_hdlr_add_anchor), where an anchor name string is shared between a node's node->anchor field and the parser's anchors-table key; freeing the node frees the shared key, and a subsequent anchor redefinition makes st_delete/st_strcmp compare against freed heap memory. Any Perl application that calls Load or LoadFile on untrusted YAML is affected on the default code path (anchors need no special flags). Reported by CPANSec and disclosed via oss-security; publicly documented proof-of-concept trigger inputs exist, but there is no CISA KEV listing and no evidence of active exploitation.
Out-of-bounds read in the Perl module YAML::Syck before 1.47 lets a remote attacker leak adjacent process memory by feeding a crafted YAML document to Load or LoadFile. The bundled libsyck base64 decoder (syck_base64dec) indexes its 256-entry b64_xtable with a signed char, so any !!binary byte >= 0x80 sign-extends to a negative index and reads before the table; because !!binary is a standard tag processed on the default Load path (not gated by $LoadBlessed or $LoadCode), the flaw is reachable without any opt-in. No CISA KEV listing and EPSS is low (0.19%, 8th percentile), so no public weaponized exploit is identified at time of analysis, though the exact trigger strings (e.g. '--- !!binary \x80\x80\x80\x80') are publicly documented in the vendor's CI test suite and the oss-security advisory.
Remote denial of service in CoreDNS versions prior to 1.14.4 allows an unauthenticated attacker to crash the DNS server with a single 28-byte UDP datagram when the proxyproto plugin is enabled. The malformed PROXY protocol v2 header triggers a nil pointer dereference in the PacketConn.ReadFrom log path, killing the process before per-request recovery can intervene. No public exploit identified at time of analysis, though the fixing PR includes a reproducer test that encodes the exact crashing byte sequence; not listed in CISA KEV.
Improper TLS hostname verification in the Snowflake Connector for Python (versions before 4.7.1) lets an on-path attacker defeat HTTPS certificate validation, accepting any certificate signed by any trusted CA regardless of the requested hostname. An adversary who can intercept traffic can decrypt and tamper with connector sessions, exposing Snowflake credentials, query results, and staged file data, and can inject arbitrary SQL bounded by the victim role's privileges. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the reporting vendor (Snowflake) rates it CVSS 4.0 9.2.
Uncontrolled memory allocation in Grafana Loki lets remote unauthenticated users issue queries with excessively large limit values, forcing the service to allocate large amounts of memory and potentially exhausting host resources. The impact is denial of service (CVSS 7.5, A:H only) and varies by deployment topology - a single-binary or under-provisioned deployment is far more exposed than a horizontally scaled microservices setup. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; note the input 'Information Disclosure' tag conflicts with the CVSS impact (C:N/I:N/A:H), which indicates an availability-only issue.
Remote denial of service in Datadog's dd-trace-go APM library lets unauthenticated attackers exhaust CPU and memory on any instrumented HTTP service by sending an oversized W3C 'baggage' header. The DD_TRACE_BAGGAGE_MAX_ITEMS (64) and DD_TRACE_BAGGAGE_MAX_BYTES (8192) safety limits were enforced only on baggage injection, not extraction, so a single crafted request with a huge number of comma-separated key-value pairs forces one hash-map allocation per pair on every request. Because baggage propagation is enabled by default, any internet-facing Go service using an affected tracer is exposed; there is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in Red Hat OpenShift GitOps (Argo CD operator) lets a tenant who controls a namespace-scoped Argo CD instance delete a ClusterRole belonging to a cluster-scoped Argo CD instance by crafting a name collision. Because the ClusterRole reconciler skips ownership validation (CWE-862), a low-privileged tenant can disrupt a higher-privileged, cluster-wide GitOps instance across the trust boundary. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the cross-tenant scope change makes it a meaningful multi-tenancy integrity concern.
Command injection in LiteLLM 1.18.10 lets attackers who can configure MCP (Model Context Protocol) servers supply arbitrary `command` and `args` values in the server-creation JSON, which LiteLLM passes to the host OS without validation, yielding remote code execution as the LiteLLM process. The flaw is part of the broader MCP-stdio supply-chain advisory disclosed by ox.security across the AI ecosystem and is documented in LiteLLM's own April 2026 advisory. No public exploit is identified in the provided data, and EPSS is low (0.32%, 24th percentile), so widespread automated exploitation is not currently indicated despite the CVSS 9.8 rating.
Arbitrary file write via symlink traversal in Rclone prior to 1.74.4 lets an attacker-controlled remote escape the local sync destination when a victim runs a copy/sync with the -l/--links flag. Rclone stores symlinks as .rclonelink text objects and recreates them on the local target without validating the link target, so a malicious remote can plant an escaping symlink and have a subsequent object write land outside the chosen destination with attacker-chosen contents. Publicly available exploit code exists (GHSA PoC), but there is no evidence of active exploitation and EPSS is low (0.34%).
Denial of service in the Netty netty-codec-stomp module (versions 4.1.x up to 4.1.135.Final and 4.2.0.Alpha1 through 4.2.15.Final) allows a remote attacker to trigger an OutOfMemoryError and crash the JVM. The StompSubframeDecoder caps individual header line length via maxLineLength but never bounds the total header count or cumulative header size, so a single STOMP frame packed with thousands of short headers exhausts heap memory. Publicly available exploit code exists (a working client/server PoC is published in the GitHub Security Advisory), but there is no public evidence of active exploitation; EPSS/KEV signals are not present in the input.
Use-after-free in Google Chrome's UI component on Linux (versions prior to 150.0.7871.125) lets a remote attacker trigger heap corruption through a crafted HTML page, but only after luring the victim into performing specific UI gestures. Rated High severity by Chromium and CVSS 7.5, the flaw carries full confidentiality, integrity, and availability impact and could lead to code execution inside the renderer, though no public exploit identified at time of analysis and SSVC records exploitation status as none. EPSS is low (0.29%, 21st percentile), consistent with the high attack complexity and required user interaction.
Remote code execution in Google Chrome's V8 JavaScript engine (versions prior to 150.0.7871.125) allows a remote attacker to run arbitrary code within the renderer sandbox when a victim visits a crafted HTML page. Rated High by Chromium and CVSS 8.8, the flaw is a type-confusion class issue in V8 requiring only that the user browse to attacker-controlled content. There is no public exploit identified at time of analysis and EPSS is low (0.34%), but Chrome's ubiquity and the total technical impact make patching urgent.
Sandbox escape in Google Chrome desktop and ChromeOS builds prior to 150.0.7871.125 stems from a use-after-free in the Skia graphics library, allowing a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a crafted HTML page. Google rates this High severity; SSVC technical impact is 'total' with a scope change (S:C), but exploitation is not observed (no public exploit identified at time of analysis) and EPSS is low at 0.24%. A vendor patch is available.
Sandbox escape in Google Chrome on Windows (versions prior to 150.0.7871.125) stems from a use-after-free in the browser's Core component, letting a remote attacker who lures a user to a crafted HTML page corrupt memory and potentially break out of the renderer sandbox. The flaw is rated High by Chromium and carries a 9.6 CVSS due to scope change and full CIA impact, though it requires user interaction (visiting the page). There is no public exploit identified at time of analysis, and CISA's SSVC framework marks exploitation as none, with a low EPSS probability of 0.26%.
Sandbox escape in Google Chrome for Android (versions prior to 150.0.7871.125) stems from a use-after-free in the GPU process, allowing an attacker who has already compromised the renderer to break out of the browser sandbox via a crafted HTML page. Rated High by Chromium with a CVSS of 8.3, it carries a scope-changing, total-impact profile but is gated by prior renderer compromise, and there is no public exploit identified at time of analysis. EPSS is low (0.24%, 16th percentile) and CISA SSVC records exploitation status as none.
Sandbox escape in Google Chrome on Linux prior to 150.0.7871.125 allows an attacker who has already compromised the renderer process to break out of the sandbox via a crafted HTML page, chaining from renderer compromise to broader host access. The flaw resides in the Linux Toolkit Theming component (CWE-20, insufficient input validation) and is rated High by Chromium with a CVSS of 8.3. There is no public exploit identified at time of analysis, EPSS is low (0.26%), and CISA SSVC lists exploitation status as none, so this is a defense-in-depth-critical but not currently exploited issue.
Renderer-side arbitrary code execution in Google Chrome for Windows (versions prior to 150.0.7871.125) stems from a heap buffer overflow in the bundled libyuv video color-conversion library, letting a remote attacker who lures a victim into loading a crafted video file run code within the renderer sandbox. Chromium rates the severity High; the flaw was reported internally by the Chrome team and a fixed stable build is available. There is no public exploit identified at time of analysis, and EPSS is low (0.33%, 25th percentile), consistent with SSVC exploitation status 'none'.
Heap corruption in Google Chrome's Ozone graphics/windowing layer (versions prior to 150.0.7871.125) lets a remote attacker who lures a victim to a crafted HTML page and coaxes them into specific UI gestures trigger a use-after-free with total technical impact. Chromium rates the underlying bug Critical, though the CVSS is 7.5 because exploitation hinges on user interaction and high attack complexity. There is no public exploit identified at time of analysis, EPSS risk is low (0.30%, 22nd percentile), and CISA SSVC records exploitation status as none.
Heap corruption in Google Chrome's Ozone component on Linux (versions prior to 150.0.7871.125) allows a remote attacker to potentially execute arbitrary code within the browser process after luring a victim to a crafted HTML page and coaxing them into specific UI gestures. Chromium rated the flaw Critical severity, though its practical exploitability is tempered by the required user interaction and high attack complexity. There is no public exploit identified at time of analysis, and CISA's SSVC framework records exploitation status as 'none'.
Network denial of service in Microsoft .NET 8.0, 9.0, and 10.0 (and the corresponding Visual Studio 2022/2026 tooling) allows an unauthorized remote attacker to exhaust system resources and render affected applications unavailable. The flaw stems from allocation of resources without limits or throttling, meaning a single crafted network interaction can trigger disproportionate resource consumption. Reported by Microsoft with a vendor patch available; no public exploit identified at time of analysis and it is not listed in CISA KEV.
