This repository contains a proof-of-concept (PoC) exploit for CVE-2022-24494, a vulnerability in the Microsoft Windows AFD (Ancillary Function Driver) driver. The exploit is implemented in C++ (PoC_AFD.cpp) and demonstrates an arbitrary kernel memory read by sending a specially crafted input buffer to the AFD driver using DeviceIoControl with IOCTL code 0x000120db. The exploit sets up a TCP socket on port 1337, then abuses the vulnerability to read from an arbitrary kernel address, which can result in a system crash (BSOD) or potentially leak kernel memory. The README.md provides a detailed technical explanation of the vulnerability, including root cause analysis, memory address manipulation, and references to further research. The repository is structured simply, with one code file and a README, and is intended as a PoC for local privilege escalation or denial of service on vulnerable Windows systems.
