CVE-2017-8623
Windows Hyper-V in Windows 10 1607, 1703, and Windows Server 2016 allows a denial of service vulnerability when it fails to properly validate input from a privileged user on a guest operating system, aka "Windows Hyper-V Denial of Service Vulnerability".
Does this matter?
Lower severity and a low EPSS score (6.52%). Track it; it rarely justifies an emergency change on its own.
