CVE-2026-45929

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the ovpn net xmit() function. When building the skb list, the skb share check function frees the original skb (socket buffer) if it is shared. The system then continues to use this stale skb pointer for peer lookup, skb dst drop(), and ovpn peer stats increment tx() operations.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
