Description
In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently.
Weaknesses (CWE)
- CWE-362 — Concurrent Execution using Shared Resource with Improper Synchronization
