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

mptcp: fix race condition in mptcp_schedule_work()

syzbot reported use-after-free in mptcp_schedule_work() [1]

Issue here is that mptcp_schedule_work() schedules a work, then gets a refcount on sk->sk_refcnt if the work was scheduled. This refcount will be released by mptcp_worker().

[A] if (schedule_work(...)) { [B] sock_hold(sk); return true; }

Problem is that mptcp_worker() can run immediately and complete before [B]

We need instead :

sock_hold(sk);
if (schedule_work(...))
    return true;
sock_put(sk);

[1] refcount_t: addition on 0; use-after-free.
