Local privilege escalation via GRFX race condition
Published Aug 12, 2025 · Updated Feb 26, 2026
A race condition in Microsoft Windows Win32K-GRFX allows local users with low privileges to elevate privileges on affected builds. Concurrent GRFX operations access a shared resource without proper synchronization, creating a use-after-free timing window. A low-privilege local account is required; exploitation needs no user interaction or network reachability.

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.
