CVE-2024-38249

SYSTEM code execution via device-context release mishandling

Published Sep 10, 2024 · Updated Aug 10, 2026

Use-after-free in the Windows Graphics Component allows local users to execute arbitrary code with SYSTEM privileges through local execution. The win32kfull driver incorrectly handles a device context when releasing it, allowing later use of freed memory. Low-privileged code execution on an affected Windows host is required, after which the attacker can take full control as SYSTEM.
