Unauthenticated information disclosure via buffer over-read
Published May 9, 2023 · Updated Jul 10, 2025
Buffer over-read in Windows NFS Portmapper allows remote attackers to disclose memory contents through network requests. Microsoft identifies the weakness but has not published the affected buffer, request field, or incorrect read operation. The NFS port mapper must be network-reachable; the documented impact is limited to confidentiality, without integrity or availability loss.
