Local information disclosure via uninitialized resource
Published Oct 13, 2026 · Updated Oct 13, 2026
Information disclosure in Microsoft Windows Subsystem for Linux allows local users to read information through an uninitialized resource. The CNA record identifies WSL2 but does not disclose the affected resource, code path, or triggering input, and its referenced vendor advisory was inaccessible. Exploitation requires authorized local access without user interaction; the reported consequence is information disclosure, not code execution or service interruption.

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.
