This repository contains a proof-of-concept (PoC) exploit for CVE-2023-36407, a Hyper-V Elevation of Privilege vulnerability affecting Windows 11 22H2 x64 systems. The exploit targets the winhvr.sys driver, specifically the WinHvSetVpState IOCTL (control code 0x221268), which lacks proper bounds checking when copying user-supplied data to the Non-paged Pool. The main exploit logic is implemented in 'main.c', which checks for Hyper-V presence, sets up a partition, allocates a large buffer, and sends it to the vulnerable driver using DeviceIoControl. Successful exploitation results in a buffer overflow in kernel memory, causing a system crash (BSOD). The repository includes Visual Studio project files for building the exploit, and a README with detailed usage and vulnerability information. No network or remote endpoints are involved; the attack vector is local, requiring execution on the vulnerable host.
