A flaw was found in the X.Org Server. When a window is removed during an active gesture, the server fails to clean up references to the destroyed window in its gesture tracking data. A local attacker can exploit this flaw to cause a use-after-free condition—where the system accesses memory after it has been released—potentially leading to unauthorized information disclosure or a denial of service (DoS).
