Local code execution via Graphics Kernel race
Published Sep 9, 2025 · Updated Feb 20, 2026
A race condition in the Microsoft Windows Graphics Kernel allows local users to execute code after required user interaction. Microsoft has not disclosed the specific function or shared resource; the published record states only that concurrent execution accesses it without proper synchronization. Low privileges and local access are required, and successful exploitation runs attacker-controlled code in the affected Windows environment.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
