Linux Driver Exploit

What problem does it solve?

This Skill provides a comprehensive guide to exploit vulnerabilities in Linux kernel modules for privilege escalation, helping reverse engineers and security professionals identify and exploit kernel module vulnerabilities.

Core Features & Use Cases

• Module Reconnaissance: Identifies attack surfaces, device registration, and ioctl handlers.
• Vulnerability Classes: Analyzes missing capability checks, heap overflow, stack buffer overflow, use-after-free, race conditions, type confusion, and information leaks.
• Exploit Primitives: Includes arbitrary read/write, heap spraying, stack pivot, and ROP chain building.
• Privilege Escalation: Explains cred struct overwrite, commit_creds, modprobe_path overwrite, and timerfd exploit methods.
• Mitigation Bypass: Details SMEP, SMAP/PXN, KASLR, KPTI, and CFI/BPF/ hardening bypass techniques.
• Exploit Template: Provides a sample exploit template for arbitrary read/write and privilege escalation.
• Testing: Offers kernel debugging setup and finding offset instructions.
• Final Report: Summarizes the exploit process, bypasses, and results.
