CVE-2023-32434 is an integer overflow vulnerability in Apple’s IOSurfaceRoot component, the IOKit user client used for GPU surface handling. The flaw was addressed through improved input validation. Successful exploitation allows a malicious application to trigger memory corruption in kernel context and execute arbitrary code with kernel privileges. Public reporting associates this vulnerability with the Operation Triangulation exploit chain, where it was used as a kernel privilege-escalation stage against affected iOS versions released before iOS 15.7.

This repository, 'Trigon', is a deterministic kernel exploit targeting CVE-2023-32434, an integer overflow in the XNU VM layer on Apple A9-A11 devices running iOS 13 to 15.7.6. The exploit is implemented as an iOS app (Objective-C/C/assembly) and is structured as a full Xcode project. The main exploit logic resides in the 'Trigon/Exploit' directory, with key files including 'exploit.c', 'aop.c', and 'surface.c'. The exploit works by creating a malicious IOSurface object to trigger the vulnerability, then leverages custom ARM shellcode to gain arbitrary physical memory access. It escalates this to full kernel virtual memory read/write, providing powerful primitives for further exploitation or jailbreaking. The exploit is highly reliable (deterministic) and does not cause kernel panics. The app provides a simple UI that runs the exploit and displays success/failure. No network endpoints are present; all exploitation is local. The code is mature and operational, providing working kernel R/W primitives, but is not a weaponized framework. The repository is well-structured, with clear separation between exploit logic, device info, memory manipulation, and UI components.
