Local information disclosure via out-of-bounds driver read
Published Sep 8, 2026 · Updated Sep 10, 2026
Out-of-bounds read in usbaudio.sys across affected Microsoft Windows releases allows local users to disclose memory through driver access. The USB Audio Class driver reads beyond the intended buffer after insufficiently validating locally supplied data; Microsoft has not published the exact input structure or code path. Low-privilege local access is required, and the documented consequence is confidentiality loss only, without integrity or availability impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
