CVE-2025-24073

Local privilege escalation via improper input validation

Published Apr 8, 2025 · Updated Aug 10, 2026

Improper input validation in Microsoft Windows DWM Core Library allows local users with low privileges to elevate privileges locally. Microsoft identifies the affected locus as DWM Core Library but has not disclosed the input, validation failure, or code path that processes it. Authenticated local access with low privileges is required; successful exploitation raises privileges on the affected Windows host.
