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.
