Local privilege escalation via undisclosed input validation flaw
Published Apr 8, 2025 · Updated Aug 10, 2026
Improper input validation in Microsoft Windows DWM Core Library allows local users to elevate privileges on affected Windows builds. Microsoft has not disclosed the input, code locus, or invalid operation responsible for the validation failure in DWM Core Library. Exploitation requires existing low-privilege local access and grants higher privileges on the same host without user interaction.
