Hypervisor Code Integrity Elevation of Privilege Vulnerability

<p>An elevation of privilege vulnerability exists when Windows Hyper-V instruction emulation fails to properly enforce privilege levels. An attacker who successfully exploited this vulnerability could gain elevated privileges on a target guest operating system. The host operating system is not vulnerable to this attack.</p> <p>This vulnerability by itself does not allow arbitrary code to be run. However, the vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.</p> <p>The update addresses the vulnerability by correcting how privileges are enforced by Windows Hyper-V instruction emulation.</p>
