  "title": "Hypervisor Code Integrity Elevation of Privilege Vulnerability",
  "description": "\u003Cp\u003EAn 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.\u003C/p\u003E\n\u003Cp\u003EThis 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.\u003C/p\u003E\n\u003Cp\u003EThe update addresses the vulnerability by correcting how privileges are enforced by Windows Hyper-V instruction emulation.\u003C/p\u003E",
