+	<h1>Problem Description:</h1>
+	<p>A number of AMD virtualization instructions operate on host physical
+	addresses, are not subject to nested page table translation, and guest use of
+	these instructions was not trapped.</p>
+	<h1>Impact:</h1>
+	<p>From kernel mode a malicious guest can write to arbitrary host memory (with
+	some constraints), affording the guest full control of the host.</p>
