CVE-2022-26763 is an out-of-bounds access vulnerability affecting multiple Apple operating systems, including tvOS, iOS, iPadOS, watchOS, and macOS. The vulnerability arises from insufficient bounds checking, allowing a malicious application to access memory outside the intended buffer. This can lead to arbitrary code execution with system privileges.

This repository contains a macOS exploit proof-of-concept targeting the DriverKit PCI subsystem. The main components are a DriverKit system extension (PCICrash) written in C++ (PCICrash.cpp, PCICrash.iig) and a user client utility (pcicrash_userclient.m) that interacts with the extension via IOKit. The extension registers a PCI device service and exposes user client interfaces that, when triggered with specific types, perform direct PCI configuration or memory writes (e.g., writing 0x41414141 to a specific address). This can crash the system or potentially be leveraged for further exploitation. The repository includes Xcode project files, entitlements for system extension and PCI access, and shell scripts for building and signing the components. The exploit requires local access and the ability to install and activate system extensions, making it a local privilege escalation or denial-of-service proof-of-concept for macOS 11.0+ systems with PCI hardware.
