kernel: net/sched: act_api: use RCU with deferred freeing for action lifecycle

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free UAF vulnerability,...

CVE-2026-74579

CVE-2026-74579 is a vulnerability in the Linux kernel 's netfilter subsystem, specifically in the nft_payload_offload_mask() function within nft_payload.c. When building an offload match mask for a partial IPv6 address match (e.g., field_len=16, priv_len=1), the code performs a shift of 1 <

kernel: scsi: core: Wake up the error handler when final completions race against each other

Race condition vulnerabilities were found in the Linux kernel's SCSI error handler wake-up logic. Memory ordering issues in scsidechostbusy and ordering problems in scsiehinchostfailed can cause the SCSI error handler to never wake up when command completions race against each other. This leaves...

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free UAF vulnerability,...

kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...

kernel: rxrpc: Fix potential UAF after skb_unshare() failure

A flaw was found in the Linux kernel's rxrpc subsystem. This vulnerability arises when the system attempts to unshare a packet buffer, and the operation fails due to an allocation issue. This failure can lead to a Use-After-Free UAF condition, where the system attempts to access memory that has...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...
