Synopsis

The remote Windows host is affected by multiple denial of service vulnerabilities.

Description

The remote Windows host is affected by multiple denial of service vulnerabilities that can be triggered with certain central processing unit (CPU) chipsets. A local attacker with kernel-mode privileges on a Hyper-V guest can exploit this to cause all Hyper-V guests to become unresponsive.

Solution

Microsoft has released a set of patches for Windows 2008, 2008 R2, 8, 2012, 8.1, 2012 R2, and 10.
