  "description": "In the Linux kernel, the following vulnerability has been resolved:  ovpn: avoid putting unrelated P2P peer on socket release  ovpn_peer_release_p2p() is called when an OVPN UDP socket is being destroyed. It checks the currently published P2P peer and releases it only if that peer still uses the socket being destroyed.  A peer replacement can publish a new peer before the old UDP socket is destroyed. When the old socket destruction path runs afterwards, ovpn_peer_release_p2p() observes the new peer through ovpn-\u003Epeer. Since the new peer uses a different socket, the function takes the socket mismatch branch.  That branch still calls ovpn_peer_put(peer). At this point, however, peer is the currently published replacement peer, not the peer associated with the socket being destroyed. Dropping its reference can free it while ovpn-\u003Epeer still points to it, leading to later use-after-free accesses from the peer and socket cleanup paths.  KASAN reports this as a slab-use-after-free on the kmalloc-1k ovpn_peer object. In the reproducer, the object is allocated from ovpn_peer_new() via ovpn_nl_peer_new_doit(), and freed through ovpn_peer_release_rcu() from RCU callback processing. Observed access sites include ovpn_peer_remove(), ovpn_socket_release(), ovpn_nl_peer_del_notify(), and unlock_ovpn().  Fix this by returning from the socket mismatch branch without putting the peer.",
