Unauthenticated service interruption via buffer over-read
Published Nov 14, 2023 · Updated Oct 8, 2025
Buffer over-read in Microsoft Windows DHCP Server allows remote attackers to interrupt the service through network traffic. The DHCP Server service reads beyond the end of a memory buffer, but Microsoft has not disclosed the affected parser or input field. No authentication or user interaction is required, and the published consequence is limited to service availability.
