Problem Description:

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.

Impact:

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.
