Vulnerability description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error caused by an io_uring request, which is being processed on a registered file. The Unix GC runs and frees the io_uring file descriptor and all the registered file descriptors in a specific order that may allow a local user to win a race and execute arbitrary code with elevated privileges.
