The peer reference pins the netdev, and dropping the last peer reference can let netdev unregistration and module removal make progress.</p> <p>Do not release that peer reference before the callback has finished its own cleanup. If ovpn_crypto_key_slot_put runs after ovpn_peer_put, it can schedule an RCU callback backed by module text after ovpn_cleanup rcu_barrier has already run. The TX error path also freed the remaining skb after ovpn_peer_put, leaving callback cleanup outside the peer/netdev lifetime window.</p> <p>Release the key slot and free any remaining skb first, then drop the peer reference as the last callback action.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>ovpn: finish crypto callback cleanup before peer release</p> <p>Crypto completion callbacks hold both key-slot and peer references.
