Local information disclosure via out-of-bounds read
Published Jun 10, 2025 · Updated Feb 20, 2026
Out-of-bounds read in Windows Storage Management Provider allows local users to disclose sensitive memory via local provider interaction. Microsoft identifies the component and read-boundary failure but has not published the affected routine, data structure, or input that triggers the read past its buffer. Low privileges and no user interaction are required, and the demonstrated consequence is limited to local confidentiality loss.
