X.Org

X.Org is the open-source implementation of the X Window System, the foundational display server for Linux and Unix graphical interfaces. This vulnerability has a high severity rating of 7.8 and requires local access with standard user privileges to exploit, affecting confidentiality, integrity, and availability of the system. Security teams should monitor for patches when X.Org releases its fix by the June 2026 deadline and prioritize updates for systems where untrusted local users have access.
