CVE-2024-30087

Local SYSTEM code execution via improper input validation

Published Jun 11, 2024 · Updated Aug 10, 2026

Improper input validation in Microsoft Windows Win32k allows local users to execute arbitrary code as SYSTEM from a low-privilege process. The win32kfull driver fails to validate attacker-controlled input, but no public source names the routine, input, or subsequent operation. Exploitation requires the ability to run low-privileged code locally and grants complete control in the SYSTEM context.
