Hyunwoo Kim 9112bd1072 appletalk: Fix Use-After-Free in atalk_ioctl ... [ Upstream commit 189ff16722ee36ced4d2a2469d4ab65a8fee4198 ] Because atalk_ioctl() accesses sk->sk_receive_queue without holding a sk->sk_receive_queue.lock, it can cause a race with atalk_recvmsg(). A use-after-free for skb occurs with the following flow. ``` atalk_ioctl() -> skb_peek() atalk_recvmsg() -> skb_recv_datagram() -> skb_free_datagram() ``` Add sk->sk_receive_queue.lock to atalk_ioctl() to fix this issue.
