X.Org Xwayland, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6 Extended Lifecycle Support - EXTENSION 취약점
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
