CVE-2022-29582 is fixed in 33 products on 1 platform, first by DEBIAN-CVE-2022-29582, released April 22, 2022. It is not reported as exploited. Patch Radar priority: High.
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.
