CVE-2019-6207 is an out-of-bounds read vulnerability in the Apple kernel, present in iOS, macOS Mojave, tvOS, and watchOS prior to their respective 2019.2 releases. The flaw allowed a malicious application to read beyond the intended bounds of kernel memory, potentially disclosing sensitive information about the kernel memory layout. The vulnerability was due to insufficient input validation, which was later addressed by Apple in the affected OS updates.

This repository contains a proof-of-concept exploit for CVE-2019-6207, a kernel memory disclosure vulnerability affecting Apple operating systems (macOS < 10.14.4, iOS < 12.2, tvOS < 12.2, watchOS < 5.2). The exploit is implemented in C (exploit.c) and demonstrates how to leak 4 bytes of uninitialized kernel memory via the sysctl interface by abusing the NET_RT_DUMP operation. The README.md provides compilation and usage instructions, as well as a technical explanation of the vulnerability in the kernel's sysctl_dumpentry function. The exploit must be run locally on a vulnerable system and does not require elevated privileges. The repository is structured simply, with one code file and a README, and is intended for research and demonstration purposes.
This repository contains a proof-of-concept (POC) exploit for CVE-2019-6207, a kernel heap memory leak vulnerability in Apple macOS (prior to 10.14.5) and iOS (prior to 12.2). The vulnerability exists in the sysctl_dumpentry function, which allocates kernel memory without proper initialization, allowing uninitialized heap data to be copied to userland via sysctl calls. The main exploit file, 'CVE-2019-6207.c', is a C program that constructs a specific sysctl MIB array to trigger the vulnerable code path, allocates a buffer, and repeatedly calls sysctl to dump and print the leaked kernel memory in hexadecimal format. The exploit is local and requires the ability to execute code on the target system. The repository also includes a README.md with a technical explanation of the vulnerability and a GitHub Actions workflow for C/C++ CI, but the core exploit logic resides in the single C file.
