Local information disclosure via out-of-bounds read
Published Jun 10, 2025 · Updated Feb 20, 2026
Out-of-bounds read in Microsoft Windows Storage Management Provider allows local users to disclose memory on affected Windows builds. Microsoft identifies the faulty component and read type but has not published the input, function, buffer, or bounds-checking error that triggers the over-read. Exploitation requires low-privileged local access, needs no user interaction, and affects confidentiality without reported integrity or availability impact.
