Local information disclosure via out-of-bounds read
Published Aug 11, 2026 · Updated Aug 25, 2026
Out-of-bounds read in Windows Management Instrumentation on affected Microsoft Windows releases allows local users to disclose information. Microsoft has not disclosed the specific WMI code path, object, or attacker-controlled input that is read past its allocated boundary. Exploitation requires low-privilege local access and exposes memory contents, with no reported ability to modify data or interrupt service.
