FreeBSD -- Local privilege escalation in IRET handler

Problem Description: If the kernel-mode IRET instruction generates an SS or NP exception, but the exception handler does not properly ensure that the right GS register base for kernel is reloaded, the userland GS segment may be used in the context of the kernel exception handler. Impact: By causi...
