Information disclosure via uninitialized RRAS resource
Published Aug 12, 2025 · Updated Feb 13, 2026
Use of an uninitialized resource in Microsoft Windows RRAS allows remote authenticated users to disclose information over a network. Microsoft does not identify the specific resource or operation that exposes its uninitialized contents. Exploitation requires low privileges and user interaction, and the consequence is limited to reading confidential data without alteration or interruption.
