Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sockmap: The use-of-free error in udpbpfrecvmsg has been fixed. syzbot reported a use-of-free of struct skmsg in skmsgrecvmsg. 0 skmsgrecvmsg retrieves skmsg from psock-ingressmsg under a lock, but its processing does not use a...

CVE-2026-74257

A flaw was found in the Linux kernel's sockmap feature. The udpbpfrecvmsg function, responsible for handling message reception, lacks proper serialization for skmsg objects. This allows multiple threads to access and modify the same skmsg object concurrently, resulting in a use-after-free...

CVE-2026-74257

CVE-2026-74257 stems from a use-after-free in the Linux kernel sockmap path (udp_bpf_recvmsg) where sk_msg_recvmsg() can touch the same sk_msg when multiple threads race. The mitigation described in connected docs is to serialize sk_msg_recvmsg() by callers, specifically by adding a lock around u...
