Copy Fail is a Linux kernel privilege escalation exploit demonstrating a vulnerability identified as CVE-2026-31431.
The exploit addresses a local privilege escalation flaw in the Linux kernel that had remained undetected for nine years before discovery. The vulnerability was identified through automated code analysis by Xint Code, Theori's AI-driven security research tool. The repository contains the working exploit code that demonstrates how the flaw can be leveraged to gain elevated privileges on affected systems.
This repository is primarily of interest to security researchers, kernel developers, and system administrators responsible for patching and securing Linux distributions. It serves as a case study in how automated vulnerability discovery can surface long-standing kernel issues that manual review may have missed. The exploit is relevant for anyone evaluating the security posture of Linux systems or studying the effectiveness of AI-assisted security analysis in finding real-world vulnerabilities.
The project shows active security research output with focused development around a specific, reproducible vulnerability. The repository documents a concrete finding from an automated analysis pipeline, indicating ongoing work in applying machine learning techniques to kernel security analysis.
