CVE-2022-29582 (GCVE-0-2022-29582)

Vulnerability from cvelistv5 – Published: 2022-04-22 00:00 – Updated: 2024-08-03 06:26

Summary

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.

Severity

No CVSS data available.
