On June 18, 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a critical Linux kernel vulnerability, CVE‑2023‑0386, to its Known Exploited Vulnerabilities (KEV) catalog.

This flaw, found in the OverlayFS subsystem, is currently being actively exploited in the wild and allows local privilege escalation to root. This is especially concerning given recent attacks such as the PumaBot SSH hijack botnet, which exploit similar attack vectors to gain unauthorized access.

• CVE‑2023‑0386 has a CVSS score of 7.8 and affects the Linux kernel’s implementation of OverlayFS.
• The vulnerability stems from improper permission checks when copying files between different mount points in OverlayFS. Specifically, if a file with the setuid bit is copied, the kernel may not properly verify ownership (UID/GID), allowing an attacker to create a setuid root binary. Securing file access permissions, similar to restricting users to FTP access only, can help reduce attack surfaces.
• A local attacker can exploit this to gain root privileges on the affected system.
• The vulnerability was patched in 2023, but exploitation in the wild has only recently been observed and confirmed by CISA.

Today, I’m going to show you a simple but effective way to automatically block suspicious IPs using a small script and tools like iptables and Fail2Ban. These tools are powerful, lightweight, and can help secure your Linux server from brute-force attacks, bots, or any malicious traffic.

This guide is beginner-friendly and great for system administrators, students, or anyone who runs a VPS, web server, or even a home Linux server.

Coccinelle is a tool for automatic program matching and transformation that was originally developed for making large-scale changes to the Linux kernel source code (i.e., C code). Matches and transformations are driven by user-specific transformation rules in the form of abstracted patches, referred to as semantic patches. As the Linux kernel—and systems software more generally—is starting to adopt Rust, Coccinelle for Rust aims to make the power of Coccinelle available to Rust codebases.

Linux is a free and open-source operating system created in the early 1990s by the legendary Linus Torvalds. He developed the core component of the system, known as the kernel. Combined with the power of GNU software, we now have a complete operating system often referred to as GNU/Linux.

Today, Linux is everywhere – from servers and smartphones to the cloud and IoT devices. It’s trusted for its stability, flexibility, and performance, making it the backbone of modern tech infrastructure.

Learning Linux can be challenging. It requires time and dedication to truly understand how it works and how all its components fit together and function harmoniously.
