With its ability to execute arbitrary code in kernel space, eBPF has opened up new avenues for exploitation. Recently, we&rsquo;ve seen a surge in advanced eBPF exploitation techniques that bypass the kernel verifier, allowing attackers to execute malicious code with elevated privileges.</p> https://linuxeries.org/post/2026-05-04-hardening-the-linux-kernel-with-ebp/ Mon, 04 May 2026 01:38:35 +0200 https://linuxeries.org/post/2026-05-04-hardening-the-linux-kernel-with-ebp/ <h2 id="introduction-to-linux-kernel-hardening-with-ebpf">Introduction to Linux Kernel Hardening with eBPF</h2> <p>The Linux kernel is a critical component of the operating system, responsible for managing hardware resources and providing services to applications. However, its complexity and ubiquity make it a prime target for attackers. Recent CVEs (Common Vulnerabilities and Exposures) and MITRE ATT&amp;CK techniques have highlighted the need for robust security measures to protect the Linux kernel. One effective approach is to leverage eBPF (extended Berkeley Packet Filter)-based security tools for hardening the kernel.</p>
