Local low-privilege system-information disclosure
Published Sep 8, 2026 · Updated Sep 9, 2026
Information disclosure in Microsoft Windows 11 24H2, 25H2, and 26H1 allows local users to read sensitive system information. Microsoft identifies the Windows MIDI Service Module as the locus but has not disclosed the operation that exposes the data. A low-privilege local account is required; confidentiality is affected, with no reported data modification or service interruption.
