CVE-ID: CVE-2023-1393

CVE-DESC: Use-After-Free can result in elevated local privileges. If a client explicitly destroys a linker overlay window (also known as COW), Xserver will leave a dangling pointer to that window in the CompScreen structure, which will later trigger use-after-free.
CVE-STATUS: Fixed
CVE-REV: Run the yum update xorg-x11-server command to close it
