Loading vulnerability…
CVE-2022-42864 is a race condition vulnerability in the kernel of multiple Apple operating systems, including tvOS, macOS (Monterey, Ventura, Big Sur), iOS, iPadOS, and watchOS. The vulnerability arises from improper state handling, allowing an attacker-controlled app to exploit the race condition and execute arbitrary code with kernel privileges.

This repository is a proof-of-concept (PoC) exploit for CVE-2022-42864, a time-of-check-time-of-use (TOCTOU) vulnerability in Apple's IOHIDFamily, affecting macOS (prior to 13.1) and iOS (prior to 16.2). The exploit demonstrates an 'arbitrary kfree' primitive in the kernel, which can be used to trigger a kernel panic. The repository is structured as an Xcode project with a custom DriverKit extension (HIDDriver) and a macOS application (HIDDriverLoader) that loads the extension and triggers the exploit. The main exploit logic is implemented in 'HIDDriverLoader/sploit.m', which interacts with the vulnerable driver to race and corrupt kernel memory. The exploit is not weaponized and does not provide stable privilege escalation or code execution; it is intended as a research PoC to demonstrate the severity of the bug. The repository includes Swift UI code for user interaction, entitlements and plist files for driver and app configuration, and C/C++ code for the driver and exploit logic. The attack vector is local, requiring the ability to load a custom driver and interact with IOKit. No network endpoints are present; all interaction is via local system interfaces and files.
