Host interruption via uncontrolled resource consumption
Published Jun 13, 2023 · Updated Jan 1, 2025
Denial of service in Microsoft Windows Hyper-V allows remote authenticated users to interrupt the host through a network-reachable attack. Microsoft identifies uncontrolled resource consumption but has not published the affected Hyper-V code path, input, or resource-exhaustion operation. Exploitation requires low privileges and high attack complexity and affects host availability without reported confidentiality or integrity impact.
