leviathan 3ad1446489 Add cls_route4 CVE-2022-2588 module (detect-only)
11th module. net/sched cls_route4 handle-zero dead UAF — discovered
by kylebot Aug 2022, fixed mainline 5.20 (commit 9efd23297cca).
Bug existed since 2.6.39 → very wide attack surface.

- modules/cls_route4_cve_2022_2588/iamroot_modules.{c,h}:
  - kernel_range thresholds: 5.4.213 / 5.10.143 / 5.15.69 / 5.18.18 /
    5.19.7 / mainline 5.20+
  - can_unshare_userns() probes user_ns+net_ns clone availability
    (the exploit's CAP_NET_ADMIN-in-userns gate)
  - cls_route4_module_available() checks /proc/modules
  - Reports VULNERABLE if kernel in range AND user_ns allowed;
    PRECOND_FAIL if user_ns denied; OK if patched.
  - Exploit stub returns IAMROOT_PRECOND_FAIL with reference to
    kylebot's public PoC.
  - Auditd rule: tc-style sendto syscalls (rough; legit traffic
    shaping will trip — tune by user).

iamroot.c + Makefile + core/registry.h wired. CVES.md row added.

Verified on kctf-mgr (6.12.86): module reports OK, total module
count = 11.

IAMROOT

A curated, actively-maintained corpus of Linux kernel LPE exploits — bundled with their detection signatures, patch status, and version ranges. Run it on a system you own (or are authorized to test) and it tells you which historical and recent CVEs that system is still vulnerable to, and — with explicit confirmation — gets you root.

⚠️ Authorized testing only. IAMROOT is a research and red-team tool. By using it you assert you have explicit authorization to test the target system. See docs/ETHICS.md.

What this is

Most Linux LPE references are dead repos, broken PoCs, or single-CVE deep-dives. IAMROOT is a living corpus: each CVE that lands here is empirically verified to work on the kernels it claims to target, CI-tested across a distro matrix, and ships with the detection signatures defenders need to spot it in their environment.

The same binary covers offense and defense:

  • iamroot --scan — fingerprint the host, report which bundled CVEs apply, and which are blocked by patches/config/LSM
  • iamroot --exploit <CVE> — run the named exploit (with --i-know authorization gate)
  • iamroot --detect-rules — dump auditd / sigma / yara rules for every bundled CVE so blue teams can drop them into their tooling
  • iamroot --mitigate — apply temporary mitigations for CVEs the host is vulnerable to (sysctl knobs, module blacklists, etc.)

Status

Active. Bootstrap phase as of 2026-05-16. First module (copy_fail_family) absorbed from the standalone DIRTYFAIL project and is verified working end-to-end on Ubuntu 26.04 + Alma 9 + Debian 13 with full AppArmor bypass + container escape demo + persistent backdoor mode.

See CVES.md for the full curated CVE list with patch status. See ROADMAP.md for the next planned modules.

Why this exists

The Linux kernel privilege-escalation space is fragmented:

  • linux-exploit-suggester / linpeas: suggest applicable exploits, don't run them
  • auto-root-exploit / kernelpop: bundle exploits, but largely stale, no CI, no defensive signatures
  • Per-CVE single-PoC repos: usually one author, often abandoned within months of release, often only one distro

IAMROOT's bet is that there's room for a single curated bundle that (1) actively maintains a small set of high-quality exploits across a multi-distro matrix, and (2) ships detection rules alongside each exploit so the same project serves both red and blue teams.

Architecture

Each CVE (or tightly-related family) is a module under modules/. Modules export a standard interface: detect(), exploit(), mitigate(), cleanup(), plus metadata describing affected kernel ranges, distro coverage, and CI test matrix.

Shared infrastructure (AppArmor bypass, su-exploitation primitives, fingerprinting, common utilities) lives in core/.

See docs/ARCHITECTURE.md for the module-loader design and how to add a new CVE.

Build & run

make                          # build all modules
sudo ./iamroot --scan         # what's this box vulnerable to?
sudo ./iamroot --scan --json  # machine-readable output for CI/SOC pipelines
sudo ./iamroot --detect-rules --format=sigma > rules.yml
sudo ./iamroot --exploit copy_fail --i-know  # actually run an exploit
