Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation in Memory Mapped I/O (MMIO) for some 14nm Client/Xeon E3 Intel® Processors. A local user can pass specially crafted input and perform a denial of service (DoS) attack in certain virtualized environments.

Mitigation
Install updates from vendor's website.
