Summary
In the Linux kernel, the following vulnerability has been resolved:
llc: call sock_orphan() at release time
syzbot reported an interesting trace [1] caused by a stale sk->sk_wq
pointer in a closed llc socket.
In commit ff7b11aa481f ("net: socket: set sock->sk to NULL after
calling proto_ops::release()") Eric Biggers hinted that some protocols
are missing a sock_orphan(), we need to perform a full audit.
In net-next, I plan to clear sock->sk from sock_orphan() and
amend Eric patch to add a warning.
