x64 Disassembly Fundamentals for Linux Core Dump Analysis

When a Linux application crashes, a core dump is often your only clue to finding the root cause. Understanding how to read the underlying x64 disassembly is the key to unlocking these diagnostic files and resolving complex software failures. This text-based course guides you through the foundational concepts of x64 architecture, assembly language instructions, and memory layouts. By reading clear explanations and studying real-world disassembly snippets, you will develop the practical skills needed to reconstruct call stacks and diagnose crashes without relying on high-level source code. What you will learn: 1. Understand key x64 CPU registers and their specific roles in execution and data storage. 2. Read and interpret common x64 assembly instructions and memory addressing modes. 3. Analyze the structure of the stack and how function calls operate at the hardware level. 4. Reconstruct stack traces manually from raw memory dumps and register states. 5. Navigate modern Linux debugging environments and account for compiler optimizations. 6. Identify common crash patterns like segmentation faults and null pointer dereferences. The course begins with essential CPU architecture definitions and core memory concepts before moving into step-by-step disassembly analysis. You will progress from reading individual instructions to tracing complete execution flows through structured text explanations and written exercises. This course is designed for software developers, system administrators, and support engineers who are new to low-level debugging and want to understand Linux core dumps. No prior assembly experience is required. Start reading today to demystify x64 assembly and elevate your Linux troubleshooting capabilities.
