CVE-2026-68341

The CVE-2026-68341 entry documents a Linux kernel vulnerability in ovpn where unlock_ovpn() iterates a release_list with llist_for_each_entry() and calls ovpn_peer_put() inside the loop. If the last reference is dropped, the peer may be freed before the loop advances, leading to a use-after-free ...
