Service interruption through undisclosed Hyper-V flaw
Published Dec 13, 2022 · Updated Jul 22, 2025
Denial of service in Hyper-V on affected Microsoft Windows 8.1, 10, 11, and Server builds allows guest OS users to interrupt host virtualization. Microsoft has not published the vulnerable Hyper-V locus or the operation that mishandles guest-controlled input. Exploitation requires low-privileged access from an adjacent guest context and affects availability without reported data disclosure or modification.
