+ <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>
