X.Org is vulnerable to Remote Code Execution (RCE). The XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests leading to local privileges elevation on systems where the server is running privileged and remote code execution for ssh X forwarding sessions.
