Privilege escalation via out-of-bounds read
Published Jan 14, 2025 · Updated Jun 9, 2026
Out-of-bounds read in Microsoft Windows Digital Media allows local users with physical access and low privileges to elevate privileges. Microsoft identifies the component and weakness class but has not published the exact code locus, input path, or out-of-bounds operation. Exploitation requires physical access plus existing low privileges and can compromise confidentiality, integrity, and availability within the same security scope.

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.
