Unauthenticated kernel-memory disclosure via NFS
Published Jun 8, 2021 · Updated Aug 3, 2024
Information disclosure in Server for NFS in Microsoft Windows allows remote attackers to read kernel memory over the network. Microsoft has not disclosed the faulty code path or how untrusted NFS input exposes kernel-memory contents. No authentication or user interaction is required, and the reported consequence is limited to reading kernel memory.
