Loading vulnerability…
CVE-2018-4431 is a memory initialization vulnerability affecting Apple operating systems prior to iOS 12.1.1, macOS Mojave 10.14.2, tvOS 12.1.1, and watchOS 5.1.2. The issue was due to improper memory handling, where memory was not correctly initialized before use, potentially leading to the exposure of sensitive information or undefined behavior.

This repository contains a proof-of-concept (PoC) exploit for CVE-2018-4431, targeting Apple iOS 12 to 12.1 on supported devices (iPhone 5s and later, iPad Air and later, iPod Touch 6th gen). The main exploit file, PoC.c, is a C program that spawns multiple threads to race the thread_selfcounts and task_inspect syscalls, attempting to trigger a race condition in the kernel. If successful, the exploit may leak kernel memory or information via the task_inspect interface. The repository also includes a partial implementation of the task_inspect logic (task_inspect.c) and a brief README describing the target devices and CVE. The exploit is local and requires code execution on the target device. No network endpoints are present; the main fingerprintable endpoint is the use of the task_inspect syscall.
