Use-after-free vulnerability in the Xkb client resource removal logic of the X.Org X server and Xwayland. When removing a client’s Xkb resources, the XkbInterest data is freed prematurely while the associated resource reference remains active. When the client terminates, the cleanup routine attempts to delete already freed memory, causing a use-after-free that may lead to crashes or memory corruption.
