CVE-2014-4699

UnknownEPSS 2.32%

Last modified

CVE-2014-4699 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.32% chance of exploitation in the next 30 days.
