Kernel-memory disclosure to local low-privileged users
Published Mar 9, 2022 · Updated Jul 8, 2025
Information disclosure in Microsoft Windows allows local users to read protected kernel information through the NT Lan Manager Datagram Receiver Driver. Microsoft has not published the driver operation or code path that mishandles input, so the precise mechanism remains undisclosed. Exploitation requires a low-privileged local account and yields confidentiality impact without reported integrity or availability impact.
