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.
Update X.Org/Xwayland to 24.1.9 if you use the affected versions. Test the change in a non-production environment first.

hol-guard supply-chain scanXorg: xwayland: use-after-free in xkb client resource removal affects X.Org/Xwayland (generic). Severity is high. 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.
AI coding agents often install or upgrade packages automatically in generic. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
