Local information disclosure via uninitialized COM resource
Published Jan 14, 2025 · Updated Jun 9, 2026
Use of an uninitialized resource in Microsoft Windows COM allows local users to disclose sensitive information across a security boundary. Microsoft has not identified the affected COM server, the resource left uninitialized, or the operation that returns its contents. Exploitation requires low-privilege local access and no user interaction; the published impact is limited to confidentiality.
