leviathan a52f5a657f Phase 7: af_packet (CVE-2017-7308) + FUSE legacy (CVE-2022-0185)
Two more famous LPEs broadening 'THE tool' coverage:

af_packet CVE-2017-7308 (Andrey Konovalov, Mar 2017):
- AF_PACKET TPACKET_V3 ring setup integer overflow → heap write-where
- Fills 2017 coverage gap
- kernel_range: 3.18.49 / 4.4.57 / 4.9.18 / 4.10.6 / mainline 4.11+
- Needs CAP_NET_RAW via user_ns clone
- Famous as the canonical 'userns + AF_PACKET → root' research-era LPE

fuse_legacy CVE-2022-0185 (William Liu / Crusaders-of-Rust, Jan 2022):
- legacy_parse_param fsconfig heap OOB → cross-cache UAF → root
- **Container-escape angle** — relevant to rootless docker/podman/snap
  (the system admin persona's nightmare)
- kernel_range: 5.4.171 / 5.10.91 / 5.15.14 / 5.16.2 / mainline 5.17+
- Needs user_ns + mount_ns to reach legacy_load() code path
- Originally reported as FUSE-specific but actually applies to any
  fs-mount path from userns (cgroup2, etc.)

Both detect-only initially; full exploits in follow-ups.

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
