Vulnerability from osv_openeuler – Published: 2022-11-11 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

kernel security update

Details

Security Fix(es):

The vulnerability is a use-after-free that happens when an io_uring request is being processed on a registered file and the Unix GC runs and frees the io_uring fd and all the registered fds. The order at which the Unix GC processes the inflight fds may lead to registered fds be freed before the io_uring is released and has the chance to unregister and wait for such requests to finish.
