+	<h1>Problem Description:</h1>
+	<p>Certain VirtIO-based device models failed to handle errors when fetching
+	I/O descriptors.  Such errors could be triggered by a malicious guest.
+	As a result, the device model code could be tricked into operating on
+	uninitialized I/O vectors, leading to memory corruption.</p>
+	<h1>Impact:</h1>
+	<p>A malicious guest may be able to crash the bhyve process.  It may be
+	possible to exploit the memory corruption bugs to achieve arbitrary code
+	execution in the bhyve process.</p>
