mrforkbomb/cifswitch-checker-cve-2026-46243Script para comprobar si la vulnerabilidad de Linux CIFSwitch (CVE-2026-46243) nos afecta. Detecta configuraciones potencialmente vulnerables y mitigaciones sin ejecutar exploits.
Checker for Linux to identify configurations potentially vulnerable to the CIFSwitch vulnerability (CVE-2026-46243). It does not exploit the vulnerability or modify the system. The main goal is to help identify potentially affected systems and validate mitigations.
The tool performs passive checks on:
Technical Reference The original vulnerability and proof of concept (PoC) used as reference for the development of this checker can be found in the following repository: https://github.com/manizada/CIFSwitch
Clone the repository:
git clone https://github.com/MrForkBomb/CIFSwitch-Checker-CVE-2026-46243.gitcd CIFSwitch-Checker-CVE-2026-46243chmod +x CIFSwitch_Checker.sh./CIFSwitch_Checker.sh or bash CIFSwitch_Checker.sh
This script was created with the goal of providing a simple and fast way to assess the exposure of Linux systems to recent kernel vulnerabilities without needing to run exploits or potentially suspicious code.
The priority is to offer safe, reproducible, and understandable analysis in an easy way for system administrators and cybersecurity professionals.
This project is intended solely for defensive, educational, and security auditing purposes. The CIFSwitch Checker tool does not exploit the vulnerability or modify the system; it only performs passive checks to help identify potentially vulnerable configurations and validate mitigations.
