Use After Free vulnerability in Linux Kernel allows Privilege Escalation.
An improper Update of Reference Count in io_uring leads to Use-After-Free
and Local Privilege Escalation. When io_msg_ring was invoked with a fixed
file, it called io_fput_file() which improperly decreased its reference
count (leading to Use-After-Free and Local Privilege Escalation). Fixed
files are permanently registered to the ring, and should not be put
separately. We recommend upgrading past commit
