-Subject: [PATCH xserver] composite: Fix use-after-free of the COW
-
-ZDI-CAN-19866/CVE-2023-1393
-
-If a client explicitly destroys the compositor overlay window (aka COW),
-we would leave a dangling pointer to that window in the CompScreen
-structure, which will trigger a use-after-free later.
-
-Make sure to clear the CompScreen pointer to the COW when the latter gets
-destroyed explicitly by the client.
-
-This vulnerability was discovered by:
-Jan-Niklas Sohn working with Trend Micro Zero Day Initiative
