What is CVE-2014-4699?
CVE-2014-4699 is a medium-severity vulnerability in Canonical Ubuntu Linux, published on 9 Jul 2014. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-362
