SKILL: Linux Kernel Exploitation — Expert Attack Playbook

AI LOAD INSTRUCTION: Expert kernel exploitation techniques. Covers environment setup (QEMU), vulnerability classes, privilege escalation targets, kernel ROP, ret2usr, stack pivoting, and cross-cache attacks. Distilled from ctf-wiki kernel-mode sections and real-world kernel CVEs. Base models often confuse user-mode and kernel-mode exploitation constraints, especially regarding SMEP/SMAP/KPTI.
