CVE-2022-1882: Use After Free
First published: Sat May 07 2022(Updated: )
A UAF flaw in Linux Kernel found in pipes functionality. The problem located in function free_pipe_info of the fs/pipe.c. When a pipe node is freed, it doesn't make pipe->watch_queue->pipe null. When function post_one_notification is called, it will use this field, but it has been freed and watch_queue->pipe is a dangling pointer. The problem was introduced since commit db8facfc9fafacefe8a835 "watch_queue, pipe: Free watchqueue state after clearing pipe ring". Reference: <a href="https://git.kernel.org/linus/353f7988dd8413c4">https://git.kernel.org/linus/353f7988dd8413c4</a>
