  "title": "Windows Hyper-V Elevation of Privilege Vulnerability",
  "description": "\u003Cp\u003EAn elevation of privilege vulnerability exists when Windows Hyper-V on a host server fails to properly handle objects in memory. An attacker who successfully exploited these vulnerabilities could gain elevated privileges on a target operating system.\u003C/p\u003E\n\u003Cp\u003EThis vulnerability by itself does not allow arbitrary code to be run.  However, this 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 vulnerabilities by correcting how Windows Hyper-V handles objects in memory.\u003C/p\u003E",
