Local sensitive system information disclosure
Published Sep 8, 2026 · Updated Sep 9, 2026
Information disclosure in Windows MIDI Service Module allows local users to read sensitive system information from affected Windows 11 systems. Microsoft has not published the vulnerable function, the exposed data, or the operation that transfers it outside its authorized control sphere. Exploitation requires low-privileged local access and no user interaction; the consequence is confidentiality loss without data modification or service interruption.
