Local kernel-memory disclosure via sensitive log data
Published Jan 14, 2025 · Updated Jun 9, 2026
Information disclosure in Microsoft Windows Kernel allows local users to read kernel memory through sensitive data written to a log. Microsoft maps the flaw to sensitive information inserted into a log file but has not disclosed the responsible routine, log, or triggering operation. Low-privileged local access is required, and the published impact is limited to confidentiality.
