Loading vulnerability…
CVE-2023-41992 is a kernel vulnerability in Apple platforms that can allow a local attacker to elevate privileges. The flaw affects Apple operating systems including iOS, iPadOS, macOS, and watchOS, and was addressed by Apple with improved checks. Publicly available information identifies the issue only at a high level as a kernel or Kernel Framework flaw, without sufficient technical detail to reliably determine the precise root cause or vulnerable code path.

This repository is a proof-of-concept (PoC) exploit for CVE-2023-41992, a kernel vulnerability in Apple's iOS (tested on iPhone 12, iOS 16.2). The repository is structured as an Xcode project for an iOS app. The main exploit logic resides in 'p0c/p0c/ViewController.m', specifically in the 'viewDidLoad' method. The exploit manipulates Mach port reference counts and types to trigger a bug in the kernel's IPC (Inter-Process Communication) right handling, leading to a kernel crash when the app is killed. The code demonstrates the vulnerability but does not provide a full exploit chain (e.g., privilege escalation or code execution). The rest of the repository consists of standard iOS app boilerplate files, asset catalogs, and project configuration files. No network or remote endpoints are involved; the attack vector is local, requiring code execution on a vulnerable device.
