CVE-2022-41121

SYSTEM code execution via unvalidated StretchBlt pointer

Published Dec 13, 2022 · Updated Jul 22, 2025

Privilege escalation in Microsoft Windows Graphics Component allows local users to execute arbitrary code with SYSTEM privileges. The StretchBlt graphics primitive fails to validate a user-supplied value before dereferencing it as a pointer. Low-privileged code execution on the target is required, after which arbitrary code runs as SYSTEM.
