Authenticated information disclosure via uninitialized resource
Published Aug 12, 2025 · Updated Feb 13, 2026
Use of an uninitialized resource in Microsoft Windows Server RRAS allows remote authenticated users to disclose information over a network. Microsoft has not disclosed the affected code locus, the resource left uninitialized, or the input operation that exposes its contents. Exploitation requires low privileges and user interaction; the documented consequence is disclosure rather than data modification or service interruption.
