Plain English Summary
AI-powered analysis for quick understanding
An attacker with a privileged account on a virtual machine can crash the host server by running a specially crafted application, causing a denial of service. This vulnerability affects systems using Microsoft Hyper-V Network Switch, and it requires the attacker to already have elevated access within the guest operating system.
Technical Description
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. To exploit the vulnerability, an attacker who already has a privileged account on a guest operating system, running as a virtual machine, could run a specially crafted application that causes a host machine to crash. The update addresses the vulnerability by modifying how virtual machines access the Hyper-V Network Switch.
