MS16-066: Security Update for Virtual Secure Mode (3155451)

medium Nessus Plugin ID 91015

Synopsis

The remote Windows host is affected by a security feature bypass vulnerability.

Description

The remote Windows host is missing a security update. It is, therefore, affected by a security feature bypass vulnerability due to certain kernel-mode pages being marked as RWX (Read, Write, Execute) even when Hypervisor Code Integrity (HVCI) is enabled. An attacker can exploit this vulnerability, via a specially crafted application, to bypass code integrity protections.

Solution

Microsoft has released a set of patches for Windows 10.
