Exploitation Summary
EIP tracks 2 public exploits for CVE-2014-4699. PoCs published by Vitaly Nikolenko, vnik5287.
AI-analyzed exploit summary This exploit leverages a ptrace/sysret vulnerability (CVE-2014-4699) to manipulate kernel execution flow, targeting a specific Linux kernel version (3.2.0-23-generic). It attempts to overwrite the IDT and redirect execution to a user-controlled payload for privilege escalation.
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.
