Unauthenticated service interruption via uncontrolled resource allocation
Published Oct 8, 2024 · Updated Aug 19, 2026
Denial of service in Microsoft Windows Hyper-V on affected Windows Server releases allows remote attackers to interrupt host availability. Microsoft maps the flaw to uncontrolled resource allocation but has not disclosed the Hyper-V code path, request type, or resource whose consumption is left unbounded. No authentication or user interaction is required; a network-reachable attacker can exhaust availability without reported confidentiality or integrity impact.
