CVE-2026-45929

A flaw was found in the Linux kernel's `ovpn` module. A use-after-free vulnerability exists in the `ovpn_net_xmit` function where a freed `skb` (socket buffer) pointer can be used for subsequent operations. This can occur when `skb_share_check` frees the original `skb` if it is shared, leading to a stale pointer being used. This flaw could potentially lead to system instability, denial of service, or other unspecified impacts.
