Fixed In Version: xorg-server 21.1.8
Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in X.Org Server. This flaw occurs if a client explicitly destroys the compositor overlay window (aka COW), where Xserver leaves a dangling pointer to that window in the CompScreen structure, which will later trigger a use-after-free issue. The Overlay Window use-after-free issue can lead to a local privilege escalation vulnerability.

Description Sandipan Roy 2023-03-21 06:40:23 UTC 
ZDI-CAN-19866/CVE-2023-1393: X.Org Server Overlay Window Use-After-Free
Local Privilege Escalation Vulnerability

If a client explicitly destroys the compositor overlay window (aka COW),
the Xserver would leave a dangling pointer to that window in the CompScreen
structure, which will trigger a use-after-free later.
