The host is missing an important security update according to Microsoft security bulletin, MS16-066. The update is required to fix a hypervisor code integrity security feature bypass vulnerability. A flaw is present in the application, which incorrectly allows certain kernel-mode pages to be marked as Read, Write, Execute (RWX) even with Hypervisor Code Integrity (HVCI) enabled. Successful exploitation could allow attackers to bypass code integrity protections.
