X.Org
X.Org is the widely-used open-source display server that manages graphical output on Linux and Unix systems. This medium-severity vulnerability requires local access with standard user privileges to trigger, potentially exposing sensitive information while causing minor system availability issues. Security teams should monitor for patches from X.Org and prioritize testing in environments where untrusted local users have system access.
