Windows Hyper-V Denial of Service Vulnerability

A denial of service vulnerability exists when Microsoft Hyper-V Network Switch on a host server fails to properly validate input from a privileged user on a guest operating system. An attacker who successfully exploited the vulnerability could cause the host server to crash.

The update addresses the vulnerability by modifying how virtual machines access the Hyper-V Network Switch.
