Description
A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation.
The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered.
We recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8.
