介绍

# CVE-2024-21305

This repo contains the report and PoC of [CVE-2024-21305](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-21305), the non-secure Hypervisor-Protected Code Integrity (HVCI) configuration vulnerability. This vulnerability allowed arbitrary kernel-mode code execution, effectively bypassing HVCI, within the root partition. For the root cause, read the [blog post](https://tandasat.github.io/blog/2024/01/15/CVE-2024-21305.html) coauthored with Andrea Allievi ([@aall86](https://twitter.com/aall86)), a Windows Core OS engineer who analyzed and fixed the issue.

The [report](./Report/README.md) in this repo is what I sent to MSRC, which contains the PoC and an initial analysis of the issue.
