Local information disclosure via out-of-bounds read
Published May 13, 2025 · Updated Feb 13, 2026
An out-of-bounds read in the Windows Multiple UNC Provider driver allows local users to disclose unspecified information from affected Windows systems. Microsoft has not published the accessed object, malformed input, or operation that permits the driver to read beyond its intended boundary. No privileges or user interaction are required, but code must execute locally; the reported consequence is limited to information disclosure.
