This repository contains a proof-of-concept (PoC) exploit for CVE-2017-2388, a NULL pointer dereference vulnerability in the IOFireWireUserClient component of macOS (fixed in Sierra 10.12.4). The main file, IOFireWireFamily-null-deref.c, is a C program that uses the IOKit framework to interact with the IOFireWireLocalNode service. It opens a connection to this service and calls specific methods (notably setAsyncRef_IsochChannelForceStop) with crafted arguments to trigger the kernel vulnerability, resulting in a denial of service (system crash/panic). The Makefile is provided for building the exploit, and the README.md explains the vulnerability and usage context. The exploit is local and requires access to a vulnerable Mac with a FireWire port. No remote or network endpoints are involved; the only fingerprintable endpoint is the IOFireWireLocalNode IOKit service.
