Description 小龙 admin 2022-08-25 15:18:51 UTC 
A race condition was found in the Linux kernel's watch queue due to a missing lock in the pipe_resize_ring(). The race condition occurs when a thread uses ioctl(IOC_WATCH_QUEUE_SET_SIZE) to resize the pipe buffer and free the old pipe buffer, while another thread uses keyctl() to trigger a notification in the watch queue, calling post_one_notification() and accessing the freed pipe buffer. This flaw allows a local user to crash the system or escalate their privileges on the system.
