Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.


Remediation

Install update from vendor's website.
