X.Org fixed 12 security flaws in the X server and Xwayland, with the repairs shipping in xorg-server 21.1.25 and xwayland-24.1.14. Nine of the flaws can lead to arbitrary code execution.

Ten of the 12 entries say an authenticated X client can trigger the flaw, meaning a program the server already accepts a connection from. The entries for CVE-2026-93524 (the public catalogue number for a specific software flaw) and CVE-2026-93536 do not state that condition.
