In the Linux kernel, the following vulnerability has been resolved:

net/handshake: restore destructor on submit failure

handshake_req_submit() replaces sk->sk_destruct but never restores it when
submission fails before the request is hashed. handshake_sk_destruct() then
returns early and the original destructor never runs, leaking the socket.
Restore sk_destruct on the error path.
