This issue could allow a local user to crash the system or potentially escalate their privileges on the system.

CVE-2023-0494 [HIGH] CWE-416 CVE-2023-0494: A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerCl A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding s

CVE-2016-3616 [HIGH] CWE-476 CVE-2016-3616: The cjpeg utility in libjpeg allows remote attackers to cause a denial of service (NULL pointer dere The cjpeg utility in libjpeg allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or execute arbitrary code via a crafted file.

CVE-2021-3612 [HIGH] CWE-20 CVE-2021-3612: An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in ver An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well

CVE-2025-6021 [HIGH] CWE-787 CVE-2025-6021: A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calcula A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow.
