CVE-2025-21333

This exploit targets a privilege escalation vulnerability in Microsoft Windows Server 2025 Hyper-V NT Kernel Integration VSP. It leverages memory corruption techniques to elevate privileges, likely through kernel object manipulation and token stealing.

This repository contains a proof-of-concept exploit for CVE-2025-21333, targeting a Windows kernel vulnerability. The code includes structures and functions for kernel exploitation, likely involving privilege escalation via IoRing and other kernel mechanisms.

This repository contains a functional exploit for CVE-2025-21333, a Windows heap-based buffer overflow vulnerability. The exploit leverages IoRing and pipe spraying techniques to achieve arbitrary read/write primitives, with improvements over the original PoC by MrAle98.

This repository contains a functional local privilege escalation (LPE) exploit for CVE-2025-21333, a heap-based buffer overflow in Hyper-V's `vkrnlintvsp.sys` driver. The exploit leverages a pool allocation size truncation vulnerability in `VkiRootAdjustSecurityDescriptorForVmwp` to achieve arbitrary memory corruption and token manipulation for privilege escalation.
