Local information disclosure via uninitialized DRTM resource
Published Jan 13, 2026 · Updated Jan 13, 2026
Information disclosure in Microsoft Windows DRTM allows local users with high privileges to read data from an uninitialized resource. The DRTM implementation uses a resource before initializing it, exposing residual information; Microsoft has not identified the resource or code path. Exploitation requires local high-privilege access, and the published impact is limited to reading information.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
