Hyunwoo Kim 3578913b2e UPSTREAM: net/rose: Fix Use-After-Free in rose_ioctl ... [ Upstream commit 810c38a369a0a0ce625b5c12169abce1dd9ccd53 ] Because rose_ioctl() accesses sk->sk_receive_queue without holding a sk->sk_receive_queue.lock, it can cause a race with rose_accept(). A use-after-free for skb occurs with the following flow. ``` rose_ioctl() -> skb_peek() rose_accept() -> skb_dequeue() -> kfree_skb() ``` Add sk->sk_receive_queue.lock to rose_ioctl() to fix this issue.
