The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel
through 3.17.4 does not properly handle faults associated with the Stack
Segment (SS) segment register, which allows local users to cause a denial
of service (panic) via a modify_ldt system call, as demonstrated by
sigreturn_32 in the linux-clock-tests test suite.
