Bug description:
  The Linux kernel before 3.15.4 on Intel processors does not properly
  restrict use of a non-canonical value for the saved RIP address in the
  case of a system call that does not use IRET, which allows local users
  to leverage a race condition and gain privileges, or cause a denial of
  service (double fault), via a crafted application that makes ptrace
  and fork system calls.

  Break-Fix: 427abfa28afedffadfca9dd8b067eb6d36bac53f
