This repository provides a proof-of-concept (PoC) exploit for CVE-2023-36427, a vulnerability in Microsoft Windows (tested on build 10.0.22621.1928) that allows kernel-mode code in the root partition to corrupt arbitrary physical memory pages, bypassing EPT protections, by abusing the Intel Hardware Feedback Interface (HFI) MSRs. The exploit is implemented as a Windows kernel-mode driver (PoC/msr/Driver.cpp) that manipulates specific MSRs (0x1b1, 0x17d0, 0x17d1) and the nt!PpmHeteroHgsEnabled kernel variable. The exploit requires a physical machine with an Intel 12th+ gen processor, HVCI enabled, and the ability to load a driver with arbitrary MSR and kernel memory write capabilities. The repository includes the driver source code, Visual Studio project files, a detailed technical report (report.md) explaining the vulnerability, exploitation steps, and mitigation suggestions. The exploit demonstrates the ability to bypass memory access restrictions in Hyper-V environments by leveraging hardware features and system power state transitions.
