CVE-2024-26218 is an elevation of privilege vulnerability in the Windows kernel. Successful exploitation would allow an attacker to execute code or actions with higher privileges than initially granted, enabling escalation from a lower-privileged context to more powerful execution within the affected Windows system. Specific technical details about the vulnerable kernel component, root cause, and triggering conditions are not currently available in the provided information.

This repository contains a proof-of-concept (POC) exploit targeting a race condition in the Windows kernel's handling of process/thread attribute structures during process creation. The main code file, 'thread_attr_poc.c', is a C program that sets up a global attribute structure and launches a high-priority thread to rapidly flip the size field of a process attribute. Meanwhile, the main thread repeatedly calls the undocumented syscall NtCreateUserProcess with this attribute list, attempting to trigger a race condition in the kernel. The repository includes a Visual Studio solution and project files for building the exploit, as well as a 'ntdll.def' file to allow linking against the necessary undocumented syscalls. The exploit is local-only and does not provide a payload such as a shell or privilege escalation, but is intended to demonstrate the presence of a kernel vulnerability. No network endpoints or remote attack vectors are present. The code is structured as a single POC with supporting build files.
