Use After Free vulnerability in Linux Kernel allows Privilege Escalation. An improper Update of Reference Count in iouring leads to Use-After-Free and Local Privilege Escalation. When iomsgring was invoked with a fixed file, it called iofput_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.
