Hands-on x86-64 page table walk:finding a flag in physical RAM with GDB

AI Analysis
●●SolidWizardryNiche GemRabbit Hole
Actually walk page tables in GDB instead of just reading diagrams.
Strengths
- •Hands-on approach beats lecture-only learning for understanding paging concepts.
- •Pre-built kernel and initramfs remove setup friction for the lab environment.
- •Busy loop keeps process context stable so CR3 stays correct during debugging.
Weaknesses
- •Narrow audience limited to systems learners and security researchers.
- •Linux/macOS only—no Windows QEMU support documented.
