X.Org

X.Org is the open-source organization behind the X Window System, a fundamental display server used across Linux and Unix environments. This vulnerability has a high severity rating (7.8) and requires local access with standard user privileges to exploit, but once compromised delivers complete system impact including confidentiality, integrity, and availability breaches. Security teams should monitor for patches when the June 2026 vendor deadline passes and prioritize updates for systems where untrusted local users have access.
