Two famous 2017-2020-era LPEs to broaden 'THE tool for folks' coverage. Both detect-only initially; exploit ports as follow-ups. ptrace_traceme (CVE-2019-13272 — jannh @ Google P0, Jun 2019): - Famous because works on default-config systems with no user_ns required — locked-down environments were still vulnerable. - kernel_range thresholds: 4.4.182 / 4.9.182 / 4.14.131 / 4.19.58 / 5.0.20 / 5.1.17 / mainline 5.2+ - Exploit shape (deferred): fork → child PTRACE_TRACEME → parent execve setuid binary → child ptrace-injects shellcode → root. - Auditd: flag PTRACE_TRACEME (request 0) — false positives via gdb/strace; tune by exclusion. netfilter_xtcompat (CVE-2021-22555 — Andy Nguyen @ Google P0): - Bug existed since 2.6.19 (2006) — 15 years of latent vuln. Famous for that age + default-config reachability via unprivileged_userns. - kernel_range thresholds: 4.4.266 / 4.9.266 / 4.14.230 / 4.19.185 / 5.4.110 / 5.10.27 / 5.11.10 / mainline 5.12+ - detect() probes user_ns+net_ns clone; locked-down → PRECOND_FAIL. - Exploit shape (deferred): heap massage via msg_msg + sk_buff cross- cache groom → kernel R/W → cred or modprobe_path overwrite. ~400 lines port from Andy's public exploit.c. - Auditd: unshare + iptables-style setsockopt + msgsnd — combined, the canonical exploit footprint. Both wired into iamroot.c, core/registry.h, Makefile. CVES.md rows added with detailed status.

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.

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/LSMiamroot --exploit <CVE>— run the named exploit (with--i-knowauthorization gate)iamroot --detect-rules— dump auditd / sigma / yara rules for every bundled CVE so blue teams can drop them into their toolingiamroot --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 themauto-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
