Local information disclosure via sensitive error output
Published Oct 14, 2025 · Updated Oct 14, 2025
Information disclosure in Microsoft Windows USB Video Driver allows local users to read sensitive information through generated error output. The driver generates an error message that includes sensitive information, but Microsoft has not identified the error path, triggering input, or exposed data. Exploitation requires local low-privilege access and no user interaction; the reported consequence is confidentiality loss only.
