Buffer Overflow
Monthly
Buffer overflow in Linux kernel's ARM CMN performance monitoring driver allows local attackers with low privileges to execute arbitrary code and gain elevated access. The perf/arm-cmn driver fails to validate hardware configuration parameters against assumed maximum sizes, enabling memory corruption through crafted CMN device configurations. While EPSS indicates low exploitation probability (0.02%), patches are available across all maintained kernel branches (6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0) per vendor advisories. The local attack vector and requirement for low-privileged user access limit remote exploitation scenarios.
Local denial-of-service and potential memory corruption in the Linux kernel's ntb_hw_switchtec driver allows a low-privileged local user to trigger undefined behavior via a shift-out-of-bounds condition when the Non-Transparent Bridge (NTB) is configured with zero Memory Window LUTs. The flaw stems from rounddown_pow_of_two being invoked on a zero value, and although no public exploit is identified at time of analysis, the upstream fix is available across multiple stable kernel branches. EPSS is very low at 0.02%, consistent with the local attack vector and narrow hardware-dependent trigger.
Remote unauthenticated attackers can cause critical out-of-bounds writes in the Linux kernel's Distributed Lock Manager (DLM) subsystem by sending malformed network messages with unvalidated length parameters to dlm_dump_rsb_name(). When the length exceeds DLM_RESNAME_MAXLEN, dlm_search_rsb_tree() writes beyond allocated buffers, enabling arbitrary code execution, denial of service, or information disclosure. Patches available for kernel versions 6.12.75, 6.18.16, 6.19.6, and 7.0. EPSS exploitation probability is very low (0.02%, 5th percentile), and no public exploit or active exploitation has been identified at time of analysis, despite the critical CVSS 9.8 score.
Out-of-bounds read in Linux kernel CIFS client allows network attackers to achieve high-severity impacts including potential code execution, information disclosure, or denial of service when users access maliciously crafted SMB shares.

Vendor patches available across multiple stable kernel branches (6.6.136, 6.12.83, 6.18.24, 6.19.14, 7.0). EPSS score of 0.02% (5th percentile) indicates low predicted exploitation probability despite high CVSS 8.8, and no active exploitation or public POC identified at time of analysis.
Out-of-bounds memory access in Linux kernel IOAM6 networking code allows remote unauthenticated attackers to read sensitive kernel memory or crash systems via crafted IPv6 packets with IOAM trace options. The vulnerability triggers when RX queue indices from ingress devices exceed TX queue counts on egress devices, causing array boundary violations in network qdisc operations. Additionally, a missing spinlock enables race conditions in queue statistics access from concurrent softirq and process contexts. EPSS probability is very low (0.02%, 4th percentile) with no evidence of active exploitation. Vendor patches available across multiple stable kernel branches.
Memory corruption in the Linux kernel's AF_ALG crypto subsystem allows local authenticated users to execute arbitrary code or cause denial of service through a page reassignment overflow in af_alg_pull_tsgl. The vulnerability affects multiple stable kernel branches (4.14 through 7.0) and has been patched across all maintained versions. With CVSS 7.8 and low attack complexity (AC:L), this presents a realistic privilege escalation path for local attackers, though EPSS exploitation probability remains low at 0.02% and no public exploit or KEV listing exists at time of analysis.
Out-of-bounds write in Linux kernel's ocfs2 filesystem driver allows local attackers with low privileges to achieve arbitrary code execution or system crash via a corrupted ocfs2 filesystem image. Exploitation occurs during copy_file_range operations when the malicious id_count field in the inode block exceeds physical inline data capacity, causing a buffer overflow past the inode block buffer. Vendor patches are available across multiple stable kernel versions (6.6.136, 6.12.83, 6.18.24, 6.19.14, 7.0). EPSS exploitation probability is low (0.02%, 5th percentile), and no active exploitation or public POC is currently identified.
Remote heap buffer overflow in Apache HTTP Server's mod_proxy_ajp module allows complete system compromise when proxying to attacker-controlled AJP backends. Affects all versions through 2.4.66; attackers can achieve remote code execution by sending malicious AJP protocol responses that overflow a heap buffer with 4 controlled bytes. Apache released patch in version 2.4.67. Despite critical CVSS 9.8, EPSS probability remains very low (0.02%, 5th percentile) indicating minimal observed exploitation attempts, and no CISA KEV listing confirms active in-the-wild abuse. Exploitation requires specific proxy_ajp deployment configuration connecting to malicious AJP servers.
Stack-based buffer overflow in Sandboxie-Plus SbieSvc service enables sandboxed processes to escape isolation and execute code as SYSTEM. Affected versions 1.17.2 and earlier allow malicious sandboxed code to overflow a fixed 160-wide-character stack buffer in NamedPipeServer::OpenHandler via crafted named pipe open requests, bypassing the fundamental security boundary Sandboxie provides.

Exploitation requires low-privilege SMB authentication plus ability to corrupt backing filesystem metadata (offline xattr tampering or race condition). EPSS score of 0.02% indicates minimal observed exploitation activity. Vendor patches available across multiple stable kernel branches (6.12.84, 6.18.25, 7.0.2, 7.1-rc1).
Out-of-bounds write in Linux kernel's ksmbd SMB server allows memory corruption when processing extended attributes (EA) in QUERY_INFO responses. The smb2_get_ea() function performs 4-byte alignment padding without checking remaining buffer space, causing 1-3 bytes to write past allocation boundaries when EA values exactly fill the response buffer. This occurs in compound SMB2 requests where shared response buffers are tightly constrained. EPSS score of 0.02% suggests minimal observed exploitation activity, though the CVSS 9.8 critical rating reflects the theoretical network-accessible, unauthenticated attack surface. Vendor patches available across multiple stable kernel branches (6.6.136, 6.12.84, 7.0.2, 7.1-rc1). Not listed in CISA KEV. This represents the third instance of the same vulnerability pattern in ksmbd QUERY_INFO handlers, following fixes in commits beef2634f81f and fda9522ed6af.
Buffer overflow in Linux kernel's AMD CCP (Cryptographic Coprocessor) driver leaks kernel memory to userspace when retrieving PEK CSR (Platform Endorsement Key Certificate Signing Request). Affecting Linux kernel 4.16+ through 7.0.x, the vulnerability allows local authenticated users to read arbitrary kernel memory due to improper error handling when firmware returns invalid buffer length requirements. Patches available across stable branches (6.6.136, 6.12.84, 6.18.25, 7.0.2, 7.1-rc1). EPSS score of 0.02% indicates minimal observed exploitation probability, though the CVSS 7.1 reflects significant confidentiality impact. No CISA KEV listing or public exploit identified at time of analysis.
Information disclosure in Linux kernel's AMD Cryptographic Coprocessor (CCP) driver allows local authenticated attackers to leak kernel memory to userspace via out-of-bounds read. When retrieving PDH certificates through SEV ioctl, the driver incorrectly copies data to userspace even after firmware command failures, potentially reading 2084+ bytes beyond allocated buffer boundaries. EPSS score of 0.02% (5th percentile) indicates minimal observed exploitation probability. Vendor patches available across multiple stable kernel branches (6.6.136, 6.12.84, 6.18.25, 7.0.2, 7.1-rc1) per upstream commits.
Buffer overflow in Linux kernel CCP SEV driver allows local authenticated users to leak kernel memory to userspace. When the PSP firmware command to retrieve SEV CPU ID fails due to insufficient buffer size, the driver attempts to copy data beyond the allocated kernel buffer boundary, exposing up to 64 bytes of kernel memory. Exploitation requires local access with low privileges (CVSS PR:L) to invoke the SEV ioctl interface. EPSS score is very low (0.02%, 5th percentile) indicating minimal real-world exploitation observed. No public exploit identified at time of analysis, though the KASAN stack trace in the CVE description provides a clear exploitation path. Patches available across multiple stable kernel branches (6.6.136, 6.12.84, 6.18.25, 7.0.2, 7.1-rc1).
Buffer overflow in Linux kernel rxrpc subsystem allows local authenticated users to trigger memory corruption via malformed key payloads. The non-XDR parsing path in rxrpc_preparse() fails to validate ticket length against AFSTOKEN_RK_TIX_MAX, enabling unprivileged users to supply oversized tickets that cause WARN_ON() triggers and potential memory corruption when keys are read. Vendor patches available for kernel versions 6.6.136, 6.12.84, 6.18.25, 7.0.2, and 7.1-rc1. EPSS score of 0.02% indicates low observed exploitation probability, with no public exploit identified at time of analysis.
A malicious FUSE server can trigger a 24-byte buffer overflow in the Linux kernel's FUSE directory cache implementation on 4 KiB page systems. The fuse_add_dirent_to_cache() function fails to validate that directory entries fit within PAGE_SIZE before copying them to page cache, allowing a server-controlled namelen value of 4095 to produce a 4120-byte serialized record that overflows into adjacent kernel memory. This enables local attackers with FUSE mount privileges to achieve high-severity impacts including arbitrary kernel memory corruption. EPSS exploitation probability is notably low (0.02%, 5th percentile) despite the 7.8 CVSS score, and no public exploit has been identified. Patches are available across multiple stable kernel versions (6.6.136, 6.12.84, 7.0.2, 7.1-rc1, 6.18.25).

The vulnerability affects the Bluetooth interface of Wacom Intuos tablets, where report types 0x03 and 0x04 are processed without validating minimum lengths (22 and 32 bytes respectively), enabling memory reads beyond buffer boundaries. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0) with no active exploitation confirmed (EPSS 0.02%, not in CISA KEV).
Adjacent network attackers can achieve high-severity code execution, information disclosure, or denial of service in the Linux kernel HID (Human Interface Device) subsystem by exploiting a bounds-checking flaw in hid_report_raw_event(). A bogus memset() operation intended to zero unused buffer space instead creates out-of-bounds read/write conditions when processing malformed HID input reports from adjacent devices (USB, Bluetooth). Vendor patches available for stable branches 6.18.22, 6.19.12, and 7.0. EPSS score of 0.02% suggests minimal observed exploitation, but the unauthenticated adjacent-network attack vector with low complexity makes this exploitable in environments with untrusted HID peripherals.
Out-of-bounds memory writes in Linux kernel HID multitouch driver allow local authenticated users to achieve code execution or crash systems via malicious USB/HID devices. The vulnerability exists in the HID multitouch report parsing logic where mismatched report IDs in feature requests can confuse the HID core. Vendor-released patches are available across multiple kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). EPSS score is low (0.02%, 7th percentile), indicating minimal observed exploitation attempts. No public exploit code identified at time of analysis.
Race condition in Linux kernel MPLS subsystem allows local authenticated users to trigger out-of-bounds memory access via concurrent label table resizing. The vulnerability affects RCU-protected codepaths (mpls_forward, mpls_dump_routes) that can obtain inconsistent snapshots of platform_labels array metadata during resize operations, potentially leading to information disclosure or denial of service. Vendor patch available addressing the issue through seqcount-based synchronization. EPSS score of 0.02% (5th percentile) indicates very low observed exploitation probability, and no active exploitation or public POC identified.
A stack-based buffer overflow in the Linux kernel's IPv6-to-IPv4 tunneling (ip6_tunnel) code allows remote unauthenticated attackers to achieve arbitrary code execution. The vulnerability occurs when ip4ip6_err() passes a cloned skb with IPv6-formatted control buffer data to icmp_send(), which misinterprets it as IPv4 control buffer data. This type confusion causes __ip_options_echo() to read attacker-controlled packet data as a length value and copy up to that many bytes into a fixed 40-byte stack buffer, enabling remote exploitation with no prerequisites. EPSS score of 0.02% suggests limited exploitation probability despite critical CVSS 9.8 rating. Vendor-released patches are available across all maintained kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, and mainline 7.0).
A buffer overflow in the Linux kernel netfilter ctnetlink subsystem allows authenticated local attackers to read arbitrary kernel memory. The vulnerability arises when userspace provides a helper name for a new expectation that differs from the master conntrack helper, causing the kernel to read 4 bytes beyond the expectation boundary. Vendor-released patches are available across multiple stable kernel branches (6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). Despite a CVSS base score of 7.3, the EPSS score is exceptionally low (0.02%, 7th percentile), indicating minimal observed exploitation attempts, and the vulnerability is not listed in CISA KEV, suggesting no confirmed active exploitation.
Stack buffer overflow in Linux kernel Bluetooth MGMT subsystem allows local authenticated attackers to execute arbitrary code with elevated privileges. The vulnerability stems from insufficient validation of the encryption key size (enc_size) parameter when loading Long Term Keys (LTKs) via the Bluetooth management interface. When processing LE LTK requests, the kernel uses the attacker-controlled enc_size value to perform stack operations against a fixed 16-byte buffer, enabling stack corruption through oversized values. Vendor-released patches are available across all active kernel branches. EPSS exploitation probability is low (0.02%, 7th percentile), and no public exploit has been identified at time of analysis, though the attack complexity is low once local authenticated access is obtained.
Out-of-bounds memory read in Linux kernel io_uring subsystem allows local authenticated users to leak kernel memory or trigger denial of service. The vulnerability exists in io_uring's fixed buffer import logic when registering zero-length buffer regions, causing the bvec skip logic to read beyond allocated slab memory. Patches available across stable kernel branches (6.18.22, 6.19.12, 7.0). EPSS score of 0.02% (4th percentile) indicates low likelihood of widespread exploitation. No active exploitation confirmed (not in CISA KEV), no public POC identified at time of analysis.
Out-of-bounds memory read in the Linux kernel's tps53679 hwmon driver allows local low-privileged users interacting with a TI TPS53679-family voltage regulator on the I2C/PMBus to trigger a one-byte stack under-read. When i2c_smbus_read_block_data() returns a zero-length block read, tps53679_identify_chip() indexes buf[ret-1] (buf[-1]), reading one byte before the on-stack buffer, which can corrupt driver logic or leak adjacent stack data. No public exploit identified at time of analysis and EPSS is negligible (0.02%), consistent with a hardware-dependent, non-remote kernel defect rather than an internet-facing threat.
Out-of-bounds memory read in Linux kernel's Intel PMU (Performance Monitoring Unit) handling allows local authenticated attackers with low privileges to potentially access sensitive kernel memory, modify data, or cause system crashes. The flaw occurs when perf auto counter reload groups contain software events, triggering an unsafe container_of operation that can dereference memory outside valid bounds. EPSS exploitation probability is very low (0.02%, 4th percentile), and no public exploit or active exploitation has been identified at time of analysis. Patches available for kernel versions 6.18.22, 6.19.12, and 7.0.
A heap buffer overflow in the Linux kernel's wilc1000 WiFi driver allows local authenticated users to trigger memory corruption via crafted SSID scan requests.

EPSS score of 0.02% indicates minimal observed exploitation activity. Vendor patches available across multiple stable kernel branches (6.12.84, 6.18.25, 7.0.2, 7.1-rc1).
Out-of-bounds write in Linux kernel's ksmbd SMB server allows memory corruption when processing extended attributes (EA) in QUERY_INFO responses. The smb2_get_ea() function performs 4-byte alignment padding without checking remaining buffer space, causing 1-3 bytes to write past allocation boundaries when EA values exactly fill the response buffer. This occurs in compound SMB2 requests where shared response buffers are tightly constrained. EPSS score of 0.02% suggests minimal observed exploitation activity, though the CVSS 9.8 critical rating reflects the theoretical network-accessible, unauthenticated attack surface. Vendor patches available across multiple stable kernel branches (6.6.136, 6.12.84, 7.0.2, 7.1-rc1). Not listed in CISA KEV. This represents the third instance of the same vulnerability pattern in ksmbd QUERY_INFO handlers, following fixes in commits beef2634f81f and fda9522ed6af.

Vendor patches available across multiple stable kernel branches (6.6.136, 6.12.84, 6.18.25, 7.0.2, 7.1-rc1) per upstream commits.
Buffer overflow in Linux kernel CCP SEV driver allows local authenticated users to leak kernel memory to userspace. When the PSP firmware command to retrieve SEV CPU ID fails due to insufficient buffer size, the driver attempts to copy data beyond the allocated kernel buffer boundary, exposing up to 64 bytes of kernel memory. Exploitation requires local access with low privileges (CVSS PR:L) to invoke the SEV ioctl interface. EPSS score is very low (0.02%, 5th percentile) indicating minimal real-world exploitation observed. No public exploit identified at time of analysis, though the KASAN stack trace in the CVE description provides a clear exploitation path. Patches available across multiple stable kernel branches (6.6.136, 6.12.84, 6.18.25, 7.0.2, 7.1-rc1).
Buffer overflow in Linux kernel rxrpc subsystem allows local authenticated users to trigger memory corruption via malformed key payloads.

Vendor patches available for kernel versions 6.6.136, 6.12.84, 6.18.25, 7.0.2, and 7.1-rc1. EPSS score of 0.02% indicates low observed exploitation probability, with no public exploit identified at time of analysis.
A malicious FUSE server can trigger a 24-byte buffer overflow in the Linux kernel's FUSE directory cache implementation on 4 KiB page systems. The fuse_add_dirent_to_cache() function fails to validate that directory entries fit within PAGE_SIZE before copying them to page cache, allowing a server-controlled namelen value of 4095 to produce a 4120-byte serialized record that overflows into adjacent kernel memory. This enables local attackers with FUSE mount privileges to achieve high-severity impacts including arbitrary kernel memory corruption. EPSS exploitation probability is notably low (0.02%, 5th percentile) despite the 7.8 CVSS score, and no public exploit has been identified. Patches are available across multiple stable kernel versions (6.6.136, 6.12.84, 7.0.2, 7.1-rc1, 6.18.25).

The vulnerability affects the Bluetooth interface of Wacom Intuos tablets, where report types 0x03 and 0x04 are processed without validating minimum lengths (22 and 32 bytes respectively), enabling memory reads beyond buffer boundaries. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0) with no active exploitation confirmed (EPSS 0.02%, not in CISA KEV).
Adjacent network attackers can achieve high-severity code execution, information disclosure, or denial of service in the Linux kernel HID (Human Interface Device) subsystem by exploiting a bounds-checking flaw in hid_report_raw_event(). A bogus memset() operation intended to zero unused buffer space instead creates out-of-bounds read/write conditions when processing malformed HID input reports from adjacent devices (USB, Bluetooth). Vendor patches available for stable branches 6.18.22, 6.19.12, and 7.0. EPSS score of 0.02% suggests minimal observed exploitation, but the unauthenticated adjacent-network attack vector with low complexity makes this exploitable in environments with untrusted HID peripherals.

EPSS score is low (0.02%, 7th percentile), indicating minimal observed exploitation attempts. No public exploit code identified at time of analysis.
Race condition in Linux kernel MPLS subsystem allows local authenticated users to trigger out-of-bounds memory access via concurrent label table resizing. The vulnerability affects RCU-protected codepaths (mpls_forward, mpls_dump_routes) that can obtain inconsistent snapshots of platform_labels array metadata during resize operations, potentially leading to information disclosure or denial of service. Vendor patch available addressing the issue through seqcount-based synchronization. EPSS score of 0.02% (5th percentile) indicates very low observed exploitation probability, and no active exploitation or public POC identified.
A stack-based buffer overflow in the Linux kernel's IPv6-to-IPv4 tunneling (ip6_tunnel) code allows remote unauthenticated attackers to achieve arbitrary code execution. The vulnerability occurs when ip4ip6_err() passes a cloned skb with IPv6-formatted control buffer data to icmp_send(), which misinterprets it as IPv4 control buffer data. This type confusion causes __ip_options_echo() to read attacker-controlled packet data as a length value and copy up to that many bytes into a fixed 40-byte stack buffer, enabling remote exploitation with no prerequisites. EPSS score of 0.02% suggests limited exploitation probability despite critical CVSS 9.8 rating. Vendor-released patches are available across all maintained kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, and mainline 7.0).
A buffer overflow in the Linux kernel netfilter ctnetlink subsystem allows authenticated local attackers to read arbitrary kernel memory. The vulnerability arises when userspace provides a helper name for a new expectation that differs from the master conntrack helper, causing the kernel to read 4 bytes beyond the expectation boundary. Vendor-released patches are available across multiple stable kernel branches (6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). Despite a CVSS base score of 7.3, the EPSS score is exceptionally low (0.02%, 7th percentile), indicating minimal observed exploitation attempts, and the vulnerability is not listed in CISA KEV, suggesting no confirmed active exploitation.
Stack buffer overflow in Linux kernel Bluetooth MGMT subsystem allows local authenticated attackers to execute arbitrary code with elevated privileges. The vulnerability stems from insufficient validation of the encryption key size (enc_size) parameter when loading Long Term Keys (LTKs) via the Bluetooth management interface. When processing LE LTK requests, the kernel uses the attacker-controlled enc_size value to perform stack operations against a fixed 16-byte buffer, enabling stack corruption through oversized values. Vendor-released patches are available across all active kernel branches. EPSS exploitation probability is low (0.02%, 7th percentile), and no public exploit has been identified at time of analysis, though the attack complexity is low once local authenticated access is obtained.
Out-of-bounds memory read in Linux kernel io_uring subsystem allows local authenticated users to leak kernel memory or trigger denial of service. The vulnerability exists in io_uring's fixed buffer import logic when registering zero-length buffer regions, causing the bvec skip logic to read beyond allocated slab memory. Patches available across stable kernel branches (6.18.22, 6.19.12, 7.0). EPSS score of 0.02% (4th percentile) indicates low likelihood of widespread exploitation. No active exploitation confirmed (not in CISA KEV), no public POC identified at time of analysis.
Out-of-bounds memory read in the Linux kernel's tps53679 hwmon driver allows local low-privileged users interacting with a TI TPS53679-family voltage regulator on the I2C/PMBus to trigger a one-byte stack under-read. When i2c_smbus_read_block_data() returns a zero-length block read, tps53679_identify_chip() indexes buf[ret-1] (buf[-1]), reading one byte before the on-stack buffer, which can corrupt driver logic or leak adjacent stack data. No public exploit identified at time of analysis and EPSS is negligible (0.02%), consistent with a hardware-dependent, non-remote kernel defect rather than an internet-facing threat.
Out-of-bounds memory read in Linux kernel's Intel PMU (Performance Monitoring Unit) handling allows local authenticated attackers with low privileges to potentially access sensitive kernel memory, modify data, or cause system crashes. The flaw occurs when perf auto counter reload groups contain software events, triggering an unsafe container_of operation that can dereference memory outside valid bounds. EPSS exploitation probability is very low (0.02%, 4th percentile), and no public exploit or active exploitation has been identified at time of analysis. Patches available for kernel versions 6.18.22, 6.19.12, and 7.0.
A heap buffer overflow in the Linux kernel's wilc1000 WiFi driver allows local authenticated users to trigger memory corruption via crafted SSID scan requests. The driver miscalculates buffer size due to u8 integer overflow (330 bytes wrapping to 74), causing kmalloc to allocate 75 bytes while memcpy writes up to 331 bytes - a 256-byte overflow. Patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). EPSS score of 0.03% (9th percentile) suggests low likelihood of widespread exploitation, and CISA KEV does not list this CVE, indicating no confirmed active exploitation at time of analysis.
Out-of-bounds read in Linux kernel iwlwifi driver allows adjacent network attackers to disclose sensitive kernel memory or trigger denial of service without authentication. The vulnerability affects the iwlwifi wireless driver's network detection match handler function, where insufficient packet length validation enables memcpy to read beyond allocated buffer boundaries. EPSS probability is low (0.02%, 7th percentile) and no active exploitation confirmed (not in CISA KEV). Vendor patches available across multiple kernel stable branches (6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0).
Stack buffer out-of-bounds read in Linux kernel ALSA snd_usb_caiaq driver allows local authenticated users to disclose kernel stack memory and potentially trigger denial of service. The vulnerability affects systems with USB audio devices using the caiaq driver when product names contain many non-ASCII characters. Present since kernel v2.6.31-rc1 (June 2009), this 16-year-old off-by-one error lacks null terminator validation during whitespace stripping. EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. Vendor patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0).
Out-of-bounds array access in Linux kernel ALSA ctxfi driver allows local authenticated users to achieve arbitrary code execution with high integrity and confidentiality impact. The flaw stems from improper SPDIF1 DAIO type handling in daio_device_index() for hw20k2 hardware, which returns -EINVAL instead of a valid index, leading to buffer overflow conditions (CWE-129). Vendor patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). EPSS score of 0.02% (5th percentile) indicates minimal observed exploitation activity; no CISA KEV listing or public POC identified at time of analysis.
Integer overflow in Linux kernel io_uring subsystem allows local authenticated users to trigger slab-out-of-bounds memory reads and denial of service. The vulnerability stems from improper type casting of user-supplied length values in network bundled receive/send operations, where values exceeding INT_MAX cause negative overflow leading to infinite loops and out-of-bounds array access. EPSS score of 0.02% (5th percentile) indicates low probability of widespread exploitation. Vendor patches available for affected stable kernel branches (6.12.81, 6.18.22, 6.19.12, 7.0), making this a straightforward patching priority for systems running vulnerable versions with io_uring enabled.
Stack buffer overflow in Linux kernel Bluetooth subsystem allows local authenticated attackers to achieve code execution, privilege escalation, or denial of service through malformed ISO socket parameters. The vulnerability occurs when binding an ISO Bluetooth socket with up to 31 BIS entries while the hci_le_big_create_sync() function only allocates stack space for 17 entries, resulting in a 14-byte overflow that corrupts adjacent stack memory. Patches are available across multiple kernel versions (6.12.81, 6.18.22, 6.19.12, 7.0), with EPSS indicating 0.02% exploitation probability and no active exploitation confirmed.
Integer overflow in AMD GPU driver's user queue doorbell handling allows local authenticated users to corrupt kernel memory and potentially escalate privileges. The amdgpu driver fails to validate user-supplied doorbell_offset values before calculating buffer offsets, enabling out-of-bounds writes to kernel doorbell space. Patches available in Linux 6.18.22, 6.19.12, and 7.0. EPSS score of 0.02% (4th percentile) indicates low probability of mass exploitation, though CVSS 7.1 reflects serious local privilege escalation potential. No active exploitation confirmed; attack requires local authenticated access to systems with AMD GPU hardware.
Out-of-bounds array access in the st_lsm6dsx IMU driver allows local authenticated users with low privileges to achieve high-impact code execution, data disclosure, or denial of service. The vulnerability exists in the buffer sampling frequency sysfs handler, which fails to validate sensor type before indexing a 2-entry array with sensor IDs beyond accelerometer and gyroscope. Exploitation requires write access to sysfs attributes for non-standard sensor types in the driver. EPSS exploitation probability is very low (0.02%, 5th percentile), no active exploitation confirmed, and vendor patches are available for Linux 6.19.12 and 7.0.
Buffer overflow in Linux kernel COMEDI me_daq driver allows local authenticated users to achieve arbitrary code execution with kernel privileges. The me2600_xilinx_download() function fails to validate firmware file length before reading data streams, enabling out-of-bounds memory access during firmware loading operations. Patches available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). EPSS score of 0.02% (7th percentile) indicates low probability of widespread exploitation despite high CVSS 7.8 rating, and no active exploitation or public exploit code identified at time of analysis.
Out-of-bounds write in Linux kernel comedi me4000 driver firmware loader allows local authenticated users to achieve high-impact code execution, data corruption, or system crash. The me4000_xilinx_download() function blindly trusts firmware file format headers without validating buffer boundaries, reading a length field from the first 4 bytes and then reading that many bytes from offset 16 without checking total file size. Patch available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0). EPSS score of 0.02% (7th percentile) indicates very low observed exploitation probability despite CVSS 7.8 rating. No public exploit code or active exploitation confirmed.
Memory corruption in the Linux kernel zynqmp_nvmem driver allows local authenticated users to achieve privilege escalation through undersized DMA buffer exploitation. The vulnerability stems from incorrect buffer size calculations in dma_alloc_coherent and memcpy operations, enabling heap or memory corruption that can lead to complete system compromise. With a 7.8 CVSS score but only 0.02% EPSS (5th percentile), this represents a high-severity issue affecting specific Xilinx Zynq UltraScale+ deployments rather than a widespread exploitation target. Patches available across multiple stable kernel branches (6.12.81, 6.18.22, 6.19.12, 7.0) with upstream fixes confirmed in git commits.
Memory corruption in the Linux kernel virtual terminal (vt) subsystem allows local authenticated users to trigger kernel crashes and potentially escalate privileges. When a console switches to an alternate screen and then gets resized, the saved Unicode buffer retains stale dimensions. Upon returning to the primary screen, operations like screen clearing (csi_J) access memory out of bounds using current dimensions against the old buffer, causing kernel oops. EPSS exploitation probability is low (0.02%, 4th percentile), no active exploitation confirmed, but vendor patches are available across multiple stable kernel branches (5.x, 6.18.x, 6.19.x).
Out-of-bounds array access in Linux kernel UCSI (USB Type-C Connector System Software Interface) driver allows local authenticated attackers to achieve arbitrary code execution or system crash. A malicious USB-C device or compromised firmware can send a crafted CCI (Connector Change Indicator) message with an invalid connector number (0-127) that exceeds the allocated connector array bounds (typically 2-4 entries), triggering memory corruption in ucsi_connector_change(). Vendor patches available for kernel 6.12.81, 6.18.22, 6.19.12, and mainline 7.0. EPSS score of 0.02% (5th percentile) indicates very low observed exploitation probability, and no active exploitation or public POC currently identified.
Local privilege escalation via stack out-of-bounds write affects the f_uac1_legacy USB Audio Class 1.0 gadget driver in the Linux kernel, where f_audio_complete() memcpy's a host-controlled req->length into a fixed 4-byte stack variable without validation. A device operating in USB gadget/peripheral mode can be driven by a malicious or crafted USB host to corrupt kernel stack memory, yielding CVSS 7.8 (High) with full confidentiality, integrity and availability impact. No public exploit is identified at time of analysis and EPSS is negligible (0.02%), but the flaw is upstream-patched across many stable trees.
