Guest-to-host code execution
Published Feb 9, 2022 · Updated Jan 2, 2025
Remote code execution in Microsoft Windows Hyper-V allows guest OS users to execute code on the host through a crafted guest operation. Microsoft has not disclosed the affected Hyper-V component or the incorrect operation performed on guest-controlled input. Exploitation requires an attacker-controlled guest and user interaction, and successful exploitation crosses the virtualization boundary into the host.
