In the Linux kernel, the following vulnerability has been resolved: net/x25: Fixed a leak in x25lapbreceiveframe. x25lapbreceiveframe uses skbcopy to obtain a private copy of an skb. The newly created skb should be freed in the under-sized/fragmented skb error handling path. Otherwise, a memory...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the x25bind function in the net/x25/afx25.c file within the Linux kernel version v5.12-rc5. A failure in the bounds check allows a local attacker with a user account on the system to access out-of-bounds memory, resulting in a system crash or...

In the Linux kernel, the following vulnerability has been resolved: net/x25: fix use-after-free of the socket by its timers The x25 timers are armed with modtimer and cancelled with timerdelete, so a pending timer holds no reference on the socket and a cancel does not wait for a callback already...

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...
