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.
