Memory Corruption
Monthly
Use-after-free in Linux kernel packet socket handling allows local attackers with low privileges to achieve kernel memory corruption, potentially leading to privilege escalation, information disclosure, or denial of service. The vulnerability stems from a race condition in packet_release() where NETDEV_UP events can re-register a socket into a fanout group's array after cleanup begins but before the socket number is zeroed, leaving dangling pointers. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score is low (0.02%, 7th percentile) and no active exploitation is confirmed (not in CISA KEV), suggesting limited real-world exploitation despite high CVSS 7.8 rating.
Type confusion in Linux kernel team driver allows local authenticated users to trigger memory corruption and potential privilege escalation. The team_setup_by_port() function incorrectly copies header_ops from non-Ethernet lower devices (such as GRE interfaces) without proper context validation, causing callbacks like dev_hard_header() to interpret netdev_priv() as the wrong structure type when processing stacked network topologies (e.g., gre → bond → team). While CVSS rates this 7.8 (High), EPSS probability is very low at 0.02% (5th percentile), and no active exploitation or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0).
Use-after-free in Linux kernel ICSSG PRU Ethernet driver allows remote code execution with CVSS 9.8 scoring. Affects TI ICSSG network driver in kernels 6.15 through 7.0 (patched in 6.19.11 and 7.0). The flaw causes CPPI descriptors to be freed before timestamp processing completes on every received packet, creating a exploitable memory corruption condition. Despite critical CVSS scoring, EPSS probability is very low (0.02%, 5th percentile) and no active exploitation or public POC has been identified. The network attack vector (AV:N) combined with zero-day timing suggests this may be scored for worst-case remote exploitation scenario, but actual exploitability via network packets requires deeper investigation of ICSSG hardware context and packet processing pipeline.
Use-after-free in Linux kernel Bluetooth Intel driver enables local privilege escalation to kernel code execution. Affects Linux kernel 4.3 through 7.0-rc5, with patches available in versions 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0. Exploitation requires local authenticated access with low privileges (CVSS PR:L). EPSS score of 0.02% (5th percentile) indicates low probability of widespread exploitation. No public exploit code or active exploitation confirmed at time of analysis, though technical details in CVE description provide implementation roadmap.
Out-of-bounds write in the Linux kernel macb Ethernet driver allows local authenticated users with low privileges to corrupt kernel memory, potentially leading to privilege escalation, denial of service, or information disclosure. The vulnerability affects the ethtool statistics collection path where gem_get_ethtool_stats() writes statistics for MACB_MAX_QUEUES regardless of the actual number of active queues, causing a 760-byte buffer overflow when fewer queues are configured. KASAN validation confirms heap corruption with a write beyond allocated vmalloc region boundaries. No active exploitation confirmed (not in CISA KEV), and EPSS score is low (0.03%, 10th percentile), indicating minimal observed exploitation activity. Patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).

EPSS score 0.02% (5th percentile) indicates low probability of mass exploitation, and no public exploit identified at time of analysis, though CVSS 7.8 reflects high local privilege escalation potential if successfully exploited.
Use-after-free in Linux kernel media subsystem allows local authenticated attackers to potentially execute arbitrary code, escalate privileges, or cause system crashes. The race condition between MEDIA_REQUEST_IOC_REINIT and VIDIOC_REQBUFS(0) affects request-capable V4L2 media devices in kernels since version 4.20. Patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0). EPSS score of 0.02% indicates very low likelihood of mass exploitation, and no active exploitation or public POC has been identified.
A buffer validation flaw in Linux kernel's TDX guest driver (versions 6.7+) allows local authenticated attackers to leak kernel memory beyond allocated quote buffers into userspace, potentially crossing container isolation boundaries in multi-tenant TDX environments. The vulnerability stems from insufficient validation of host-controlled quote_buf->out_len values during remote attestation operations. Patches available for stable branches 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. EPSS score of 0.02% (5th percentile) indicates low exploitation probability in the wild, with no public exploit code or active exploitation confirmed at time of analysis.
Use-after-free in Linux kernel virtio_net driver allows local authenticated attackers with low privileges to potentially achieve high confidentiality, integrity, and availability impact. The flaw triggers when virtio_net is configured with napi_tx=N (non-NAPI transmit mode) and the IFF_XMIT_DST_RELEASE flag is cleared by tc route filter rules. When a network namespace is destroyed while packets remain queued in the virtio transmit ring, the freed dst_ops structure is later dereferenced during packet cleanup, causing kernel memory corruption. Vendor patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (7th percentile) suggests low probability of mass exploitation, and no active exploitation or public POC has been identified at time of analysis.
Use-after-free in Linux Kernel XFS filesystem allows local authenticated users to execute arbitrary code, escalate privileges, or cause system crashes during filesystem unmount operations. The vulnerability stems from a race condition where background reclaim and inodegc processes continue running while the Active Item List (AIL) is being flushed during unmount, enabling concurrent access to freed memory structures. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% suggests very low probability of mass exploitation, and no active exploitation or public POC is identified at time of analysis.
Use-after-free in Linux Kernel XFS file system allows local authenticated users to execute arbitrary code, escalate privileges, or cause denial of service. The vulnerability affects XFS implementations from kernel 5.9 onward due to improper handling of Active Item List (AIL) pointers when performing buffer I/O in inode and quota push callbacks. With EPSS exploitation probability at 0.02% and no confirmed active exploitation, this represents a moderate real-world risk limited by local access requirements and low attack complexity. Patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0).
Local privilege escalation in Linux Kernel ext4 filesystem allows authenticated users to trigger kernel crashes and potentially execute arbitrary code with high privileges. The vulnerability stems from improper handling of inline data conversion when truncate() operations exceed inline storage capacity in ext4 filesystems. Affected kernel versions include mainline through 7.0-rc3 and stable branches 5.10.x through 6.19.x, with vendor patches available across all active kernel series. EPSS exploitation probability is very low (0.02%, 7th percentile) and no public exploit identified at time of analysis, though CVSS 7.8 reflects high local impact if exploited.
Use-after-free in Linux kernel ext4 filesystem allows local attackers to potentially execute arbitrary code or cause denial of service during unmount operations. The vulnerability stems from a race condition between ext4_put_super() teardown and update_super_work() error notification, where sysfs_notify() accesses a freed kernfs_node object after kobject_del() has released it. Fixed in stable kernel releases 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. EPSS score of 0.02% (7th percentile) suggests low probability of exploitation in the wild, though CVSS vector indicates straightforward local exploitation requiring user interaction.
Use-after-free and NULL pointer dereference vulnerabilities in Linux kernel's ksmbd SMB server allow remote unauthenticated attackers to achieve arbitrary code execution, information disclosure, or denial of service. The flaws occur during oplock (opportunistic lock) publication when error handling frees memory still referenced by concurrent readers, and when global lease lists are accessed before critical pointers are initialized. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), this represents a critical remote attack surface, though EPSS score of 0.02% (5th percentile) suggests minimal observed exploitation activity. Vendor patches are available across affected kernel versions 6.6.130-6.19.9.
Out-of-bounds write in Linux kernel's ksmbd server allows authenticated remote attackers with low-privilege SMB access to corrupt memory and potentially execute arbitrary code or crash the system. The vulnerability triggers when processing compound SMB2 requests (e.g., READ + QUERY_INFO for security descriptors) where the first command consumes most of the response buffer, causing ksmbd to write beyond allocated memory when building security descriptors from POSIX ACLs. Vendor patches are available for kernel versions 6.12.81, 6.18.22, 6.19.12, and 7.0. EPSS score of 0.01% suggests low observed exploitation probability, and no public exploit code or active exploitation has been identified at time of analysis.
Local privilege escalation in FreeBSD 13.5 through 15.0 allows unprivileged processes to gain root privileges by exploiting a use-after-free condition in the TIOCNOTTY ioctl implementation. When a process detaches from its controlling terminal and exits, a dangling pointer in the terminal structure references freed session memory, which attackers can manipulate to escalate privileges. This vulnerability affects multiple stable and release branches with CVSS 8.4 (High) but low EPSS probability (0.02%, 5th percentile), indicating theoretical severity without observed widespread exploitation. Not listed in CISA KEV, suggesting no confirmed active exploitation at time of analysis.
Out-of-bounds buffer write in CPython's asyncio.ProactorEventLoop (Windows only) allows remote attackers to trigger memory corruption via oversized network data. The sock_recvfrom_into() method lacks buffer size validation when the nbytes parameter is used, enabling writes beyond allocated memory boundaries. Patch available via GitHub PR #148809. CVSS 8.8 reflects network-accessible attack surface with no authentication required, though exploitation is platform-specific (Windows only) and requires specific asyncio usage patterns.

High-severity denial-of-service condition in Mozilla Firefox DOM processing allows remote attackers to crash the browser via network-delivered content without authentication or user interaction. Fixed in Firefox 150, Firefox ESR 115.35, and Firefox ESR 140.10. CVSS 7.5 reflects network attack vector with low complexity (AV:N/AC:L/PR:N/UI:N) but impact limited to availability (A:H). EPSS data not provided. Not listed in CISA KEV, indicating no confirmed active exploitation. SSVC framework rates exploitation as 'none' and technical impact as 'partial', suggesting lower real-world priority despite high CVSS score.
Heap buffer overflow in SAIL image library's TGA decoder allows remote code execution via malformed RLE-compressed TGA files against all versions prior to commit 45d48d1. Network-accessible applications processing untrusted TGA images can be fully compromised without authentication or user interaction (CVSS 9.8). The raw-packet RLE decompression path permits writing up to 496 bytes of attacker-controlled data beyond allocated heap bounds. Vendor patch confirmed via GitHub commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302. No CISA KEV listing or public POC identified at time of analysis, but the straightforward exploitation conditions (parsing untrusted files) and complete technical disclosure create high weaponization risk.
Heap buffer overflow in SAIL PSD codec allows remote code execution when processing malicious LAB-mode PSD files. Affects all SAIL versions prior to commit c930284 (HappySeaFox/sail). Attackers can achieve arbitrary code execution (CVSS 9.8: AV:N/AC:L/PR:N/UI:N) by triggering a mismatch between computed bytes-per-pixel (6 bytes for 3-channel 16-bit LAB) and allocated buffer size (5 bytes for BPP40_CIE_LAB format). Every pixel write deterministically overflows the heap buffer. EPSS data not available. Not listed in CISA KEV. Patch available via GitHub commit c930284445ea3ff94451ccd7a57c999eca3bc979.
Out-of-bounds memory access in SAIL image library's XWD codec allows remote attackers to achieve arbitrary code execution via malformed image files. The vulnerability stems from a pixel format mismatch where buffer allocation uses pixmap_depth=8 (1 byte/pixel) but byte-swap operations use bits_per_pixel=32 (4 bytes/pixel), causing 4x buffer overrun. CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) indicates trivial exploitation requiring only delivery of a crafted XWD file. EPSS data unavailable; no KEV listing indicates targeted rather than widespread exploitation. Fix available in commit 36aa5c7ec8a2bb35f6fb867a1177a6f141156b02.

CVSS 7.8 (High) with local attack vector requiring user interaction. Fixed in version 1.8.7-r1. No confirmed active exploitation (CISA KEV), though proof-of-concept feasibility is high given the deterministic nature of the memory corruption.
Use-after-free in libsixel 1.8.7 and earlier enables local attackers to crash applications or execute arbitrary code via crafted SIXEL image frames. The vulnerability occurs when sixel_encoder_encode_bytes() processes resize operations that free caller-owned pixel buffers, creating dangling pointers exploitable through repeated, predictable frame manipulation. EPSS data not available; no confirmed active exploitation (not in CISA KEV), but the technical details suggest reliable exploitation potential for local privilege escalation or RCE scenarios.
OpenStack Keystone's LDAP identity backend grants authentication access to disabled user accounts due to improper string-to-boolean conversion logic.

Use-after-free in Linux kernel packet socket handling allows local attackers with low privileges to achieve kernel memory corruption, potentially leading to privilege escalation, information disclosure, or denial of service. The vulnerability stems from a race condition in packet_release() where NETDEV_UP events can re-register a socket into a fanout group's array after cleanup begins but before the socket number is zeroed, leaving dangling pointers. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score is low (0.02%, 7th percentile) and no active exploitation is confirmed (not in CISA KEV), suggesting limited real-world exploitation despite high CVSS 7.8 rating.
Type confusion in Linux kernel team driver allows local authenticated users to trigger memory corruption and potential privilege escalation. The team_setup_by_port() function incorrectly copies header_ops from non-Ethernet lower devices (such as GRE interfaces) without proper context validation, causing callbacks like dev_hard_header() to interpret netdev_priv() as the wrong structure type when processing stacked network topologies (e.g., gre → bond → team). While CVSS rates this 7.8 (High), EPSS probability is very low at 0.02% (5th percentile), and no active exploitation or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0).

Patches available for stable branches 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. EPSS score of 0.02% (5th percentile) indicates low exploitation probability in the wild, with no public exploit code or active exploitation confirmed at time of analysis.
Use-after-free in Linux kernel virtio_net driver allows local authenticated attackers with low privileges to potentially achieve high confidentiality, integrity, and availability impact. The flaw triggers when virtio_net is configured with napi_tx=N (non-NAPI transmit mode) and the IFF_XMIT_DST_RELEASE flag is cleared by tc route filter rules. When a network namespace is destroyed while packets remain queued in the virtio transmit ring, the freed dst_ops structure is later dereferenced during packet cleanup, causing kernel memory corruption. Vendor patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).

Use-after-free and NULL pointer dereference vulnerabilities in Linux kernel's ksmbd SMB server allow remote unauthenticated attackers to achieve arbitrary code execution, information disclosure, or denial of service. The flaws occur during oplock (opportunistic lock) publication when error handling frees memory still referenced by concurrent readers, and when global lease lists are accessed before critical pointers are initialized. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), this represents a critical remote attack surface, though EPSS score of 0.02% (5th percentile) suggests minimal observed exploitation activity. Vendor patches are available across affected kernel versions 6.6.130-6.19.9.
Out-of-bounds write in Linux kernel's ksmbd server allows authenticated remote attackers with low-privilege SMB access to corrupt memory and potentially execute arbitrary code or crash the system. The vulnerability triggers when processing compound SMB2 requests (e.g., READ + QUERY_INFO for security descriptors) where the first command consumes most of the response buffer, causing ksmbd to write beyond allocated memory when building security descriptors from POSIX ACLs. Vendor patches are available for kernel versions 6.12.81, 6.18.22, 6.19.12, and 7.0. EPSS score of 0.01% suggests low observed exploitation probability, and no public exploit code or active exploitation has been identified at time of analysis.
Local privilege escalation in FreeBSD 13.5 through 15.0 allows unprivileged processes to gain root privileges by exploiting a use-after-free condition in the TIOCNOTTY ioctl implementation. When a process detaches from its controlling terminal and exits, a dangling pointer in the terminal structure references freed session memory, which attackers can manipulate to escalate privileges. This vulnerability affects multiple stable and release branches with CVSS 8.4 (High) but low EPSS probability (0.02%, 5th percentile), indicating theoretical severity without observed widespread exploitation. Not listed in CISA KEV, suggesting no confirmed active exploitation at time of analysis.
Out-of-bounds buffer write in CPython's asyncio.ProactorEventLoop (Windows only) allows remote attackers to trigger memory corruption via oversized network data. The sock_recvfrom_into() method lacks buffer size validation when the nbytes parameter is used, enabling writes beyond allocated memory boundaries. Patch available via GitHub PR #148809. CVSS 8.8 reflects network-accessible attack surface with no authentication required, though exploitation is platform-specific (Windows only) and requires specific asyncio usage patterns.
