Local information disclosure via uninitialized resource
Published Jun 10, 2025 · Updated Feb 20, 2026
Information disclosure in Microsoft Windows DWM Core Library allows local users with low privileges to read sensitive memory contents. The DWM Core Library uses a resource before initializing it; Microsoft has not disclosed the affected routine, resource, or triggering input. A local low-privilege account is required, and the reported consequence is confidentiality loss without data modification or service interruption.
