+	<h1>Problem Description:</h1>
+	<p>The MOV SS and POP SS instructions inhibit debug exceptions
+	until the instruction boundary following the next instruction.
+	If that instruction is a system call or similar instruction
+	that transfers control to the operating system, the debug
+	exception will be handled in the kernel context instead of
+	the user context.</p>
+	<h1>Impact:</h1>
+	<p>An authenticated local attacker may be able to read
+	sensitive data in kernel memory, control low-level operating
+	system functions, or may panic the system.</p>
