Name of the Vulnerable Software and Affected Versions Windows Hyper-V versions prior to the fixed version Windows Server 2016 Windows 10 Windows 10 Servers

Description The issue is related to insufficient input validation in the Microsoft Hyper-V hardware virtualization system for Windows operating systems. This allows a remote attacker, using a specially crafted application run on a guest operating system, to execute arbitrary code on the host operating system.

Recommendations For Windows Hyper-V, update to a version that includes the fix for this issue. For Windows Server 2016, apply the necessary patch or update to resolve the vulnerability. For Windows 10 and Windows 10 Servers, ensure that all security updates are applied to mitigate the risk of exploitation. As a temporary workaround, consider restricting access to the virtualization environment until a patch is available.
