    (CVE-2023-6478)

    Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled

    memory when processing the DeviceFocusEvent and ProcXIQueryPointer APIs. An

    attacker could possibly use this issue to cause the X Server to crash,

    obtain sensitive information, or execute arbitrary code. (CVE-2023-6816)

    Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled

    reattaching to a different master device. An attacker could use this issue

    to cause the X Server to crash, leading to a denial of service, or possibly
