kernel: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the SCTPSENDALL path where a cached list entry is not properly revalidated after the socket lock is temporarily released. This allows a local attacker or a remote attacker v...

kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem.

An attacker with local access could exploit this flaw b...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

CVE-2026-77587

A flaw was found in Tor. A malicious exit node could exploit a use-after-free vulnerability in the handling of conflux objects. This occurs when a recovery leg attempts to revive a conflux set whose last linked leg has already been closed. Successful exploitation of this flaw could lead to a clie...

CVE-2026-74634

A flaw was found in the Linux kernel's ring-buffer component. This vulnerability occurs when the system attempts to change the order of sub-buffers while resizing is disabled, leading to memory being freed prematurely. A local attacker could exploit this use-after-free condition to potentially...

CVE-2026-74628

A flaw was found in the Linux kernel's x25 network protocol. The way timers are managed for x25 sockets can lead to a use-after-free vulnerability. Specifically, a timer might be rearmed after the associated socket has been deallocated, causing the system to access freed memory. This could...
