CVE-2026-68386
A flaw was found in the Linux kernel. A local attacker with BPF program capabilities could exploit a vulnerability in the BPF sockmap feature. This occurs when a BPF program increments the reference count of an unbound UDP socket, and the socket is subsequently bound. This sequence of events caus...

In the Linux kernel, the following vulnerabilities have been resolved: TCP/UDP: Fixed memory leaks related to sk and zerocopy SKBS with TX timestamps. Syzkaller reported 0 memory leaks of an UDP socket and ZEROCOPY SKBS. We can reproduce this issue with the following sequence: sk = socketAFINET,...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: pfcp: The device is destroyed along with the udp socket’s netns structure. The pfcpnewlink function links the device to a specific netns in devnet instead of net, where an udp tunnel socket is created. Even when net is removed, t...
