Local Privilege Escalation in Microsoft Windows Graphics Component
CVE-2026-23668 is a local elevation-of-privilege vulnerability in the Microsoft Windows Graphics Component. The provided content describes the issue as a race condition caused by improper locking / improper synchronization when performing operations on an object, with reporting that places the flaw in Windows graphics-related code including cdd.dll and, in one source variant, win32kfull. Microsoft characterizes it as concurrent execution using a shared resource with improper synchronization. An attacker who already has the ability to execute low-privileged code locally can exploit the flaw to win the race condition and elevate execution to a higher-privileged context. Successful exploitation results in arbitrary code execution as SYSTEM.
