Local privilege escalation via heap buffer overflow
Published Apr 11, 2023 · Updated Jan 23, 2025
A heap-based buffer overflow in the Windows Graphics Component allows local users to elevate privileges on affected Windows systems. Microsoft has not published the affected function, input path, or erroneous heap write; the CNA record identifies only the component and weakness. Exploitation requires low-privilege local access and no user interaction, and successful exploitation grants high-impact control over system data and execution.

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.
