Description

In the Linux kernel, the following vulnerability has been resolved: phonet/pep: fix racy skb_queue_empty() use The receive queues are protected by their respective spin-lock, not the socket lock. This could lead to skb_peek() unexpectedly returning NULL or a pointer to an already dequeued socket buffer.
