Linux x64 Assembly: Syscalls, Registers, and the .bss Segment
Go behind the scenes of the Linux Kernel. Learn the register protocol for syscalls and why the .bss segment is essential for efficient, zero-disk memory reservation.
RFC 1071 Checksum in x64 Assembly: One's Complement Implementation
A malformed packet is a dead packet. Learn how to implement the official RFC 1071 checksum algorithm in Assembly to ensure your custom ICMP data bypasses kernel drops.
CVE-2025-6019: udisks2 XFS Resize Vulnerability
Exploit the Time-of-Check to Time-of-Use (TOCTOU) window in udisks2. This analysis covers Polkit bypass, XFS image crafting, and Race Condition triggers for LPE.
Building a Low-Level ICMP Sniffer in x64 Assembly (Raw Sockets)
Scapy or C are easy, but true control lies in the CPU cycles. Learn how to build a raw socket sniffer from scratch in x64 Assembly, bypassing libc for pure kernel interaction.
eBPF: Safe Kernel Programmability with XDP, Kprobes & Observability
Traditional kernel modules are risky. eBPF provides a safe, high-speed ‘superpower’ for the Linux Kernel. Learn how XDP and kprobes revolutionize networking and tracing.
