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.
+ A use-after-free flaw was found in the Linux kernel’s io_uring interface subsystem in the way a user triggers a race condition between timeout flush and removal. This flaw allows a local user to crash or escalate their privileges on the system.
