CVE-2017-11176 is a use-after-free vulnerability in the Linux kernel's mq_notify function (up to version 4.11.9). The vulnerability arises because the sock pointer is not set to NULL upon entering the retry logic. If a user-space process closes a Netlink socket while another thread is in mq_notify, the kernel may dereference a freed pointer, leading to a use-after-free condition. This can be exploited by attackers to cause a denial of service (kernel crash) or potentially achieve privilege escalation, depending on the exploitation primitives available.

This repository contains a single C source file, 'cve-2017-11176.c', which is a proof-of-concept (PoC) local privilege escalation exploit targeting CVE-2017-11176, a double free (double sock_put) vulnerability in the Linux kernel's mq_notify syscall. The exploit is designed for educational purposes and is not ready for direct use; it requires adaptation for the target system, including updating kernel symbol addresses and offsets. The code demonstrates advanced kernel exploitation techniques, including heap spraying, manipulating netlink sockets, and achieving an arbitrary function call in kernel space. Upon successful exploitation, the code attempts to spawn a root shell by executing '/bin/bash'. The exploit does not target any network endpoints and is strictly a local privilege escalation vector. The repository is well-commented and references a detailed multi-part blog post explaining the vulnerability and exploitation process.
