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...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

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 a skb. The newly created skb should be freed in the under-sized/fragmented skb error handling path. Otherwise, a memory le...

CVE-2026-43011

The CVE-2026-43011 issue concerns the Linux kernel net/x25 path where a skb may be freed twice due to a double-free path: if alloc_skb fails in x25_queue_rx_frame, kfree_skb(skb) is called, and later x25_backlog_rcv may free the same skb again, causing a crash/DoS. Public advisories confirm this ...
