Unauthenticated host interruption via resource consumption
Published Oct 8, 2024 · Updated Aug 19, 2026
Denial of service in Microsoft Windows Hyper-V on affected Windows Server builds allows remote attackers to interrupt host availability. Microsoft identifies uncontrolled resource consumption but has not published the Hyper-V locus, input, or operation that exhausts the resource. No authentication or user interaction is required; exploitation can make the host unavailable without reported data disclosure or modification.
