+	<h1>Problem Description:</h1>
+	<p>On certain Intel 64-bit x86 systems there is a period
+	of time during terminal fault handling where the CPU may
+	use speculative execution to try to load data. The CPU may
+	speculatively access the level 1 data cache (L1D). Data
+	which would otherwise be protected may then be determined
+	by using side channel methods.</p>
+	<p>This issue affects bhyve on FreeBSD/amd64 systems.</p>
+	<h1>Impact:</h1>
+	<p>An attacker executing user code, or kernel code inside
+	of a virtual machine, may be able to read secret data from
+	the kernel or from another virtual machine.</p>
