Unauthenticated denial of service via buffer over-read
Published Jul 11, 2023 · Updated Jan 1, 2025
Buffer over-read in Windows Extended Negotiation allows remote attackers to interrupt affected systems via crafted network traffic. The component reads beyond a buffer boundary while processing untrusted negotiation data; Microsoft has not disclosed the responsible function or field. Exploitation requires no privileges or user interaction, and the published impact is limited to availability, although the interruption mode is undisclosed.
