AXSA:2025-11057:03 advisory.

    Xwayland is an X server for running X clients under Wayland.
    CVE-2025-62229
    A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications.
    Improper error handling during notification creation can leave dangling pointers that lead to a use-after-
    free condition. This can cause memory corruption or a crash, potentially allowing an attacker to execute
    arbitrary code or cause a denial of service.
    CVE-2025-62230
    A flaw was discovered in the X.Org X servers 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.
    CVE-2025-62231
    A flaw was identified in the X.Org X servers X Keyboard (Xkb) extension where improper bounds checking in
    the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially
    crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
