Host service interruption by local low-privileged users
Published Jan 9, 2024 · Updated May 3, 2025
Denial of service in Microsoft Windows Hyper-V allows local users with low privileges to interrupt the host through an unspecified vector. Microsoft has not identified the Hyper-V code path, triggering input, or exceptional condition that the component handles incorrectly. Exploitation requires local low-privilege access and affects availability only; the published record does not distinguish a crash from another interruption.
