CVE-2025-50168 is a local elevation of privilege vulnerability in the Windows Win32K component, specifically identified in ICOMP, caused by access of a resource using an incompatible type. This type confusion condition can allow an authorized attacker to manipulate object or resource handling in kernel-adjacent Win32K functionality and elevate privileges on the local system. Microsoft and third-party reporting identified the issue as a Win32k elevation of privilege flaw and assessed it among the vulnerabilities more likely to be exploited.

This repository contains a local privilege escalation (LPE) exploit targeting CVE-2025-50168, a vulnerability in the Win32kbase!DirectComposition component of Microsoft Windows. The exploit was submitted to Pwn2Own Berlin 2025 in the LPE category. The main exploit logic resides in 'P2O/main.cpp', which orchestrates the attack by leaking the Windows kernel base address (bypassing kASLR) using a side-channel technique (prefetch-based, with assembly in 'prefetch_asm.asm' and logic in 'prefetch_leak.h'), and then exploiting the DirectComposition vulnerability to escalate privileges. The exploit manipulates kernel memory structures to obtain SYSTEM privileges and spawns a SYSTEM shell. The codebase is written in C++ with some inline assembly and is structured as a Visual Studio project. No network endpoints are used; the attack vector is purely local. The exploit uses named pipes (\\.\pipe\inputPipe and \\.\pipe\outputPipe) for internal communication. The repository is mature and operational, providing a working LPE exploit for research and educational purposes.
