CVE-2026-45929

A flaw was found in the Linux kernel's ovpn module. A use-after-free vulnerability exists in the ovpnnetxmit function where a freed skb socket buffer pointer can be used for subsequent operations. This can occur when skbsharecheck frees the original skb if it is shared, leading to a stale pointer...
