- Implements the Dirty Pipe primitive: prepare_pipe() fills+drains a
pipe to plant the stale PIPE_BUF_FLAG_CAN_MERGE flag in every
pipe_buffer slot; dirty_pipe_write() splices 1 byte from the target
file at offset-1 (seeding the slot with the file's page) then write()s
the payload, which the buggy kernel merges back into the page cache.
- find_passwd_uid_field() + revert_passwd_page_cache() inlined in the
module. Two-of-two duplication acceptable; extraction into core/host
triggers when a third module needs the same helpers (Phase 1.5).
- dirty_pipe_exploit() resolves current euid via getpwuid, locates the
user's UID field in /etc/passwd, replaces it with same-length zeros
('0000' for a 4-digit UID), then execlp's su <user> -c /bin/sh.
Auto-refuses if detect() reports patched. --no-shell mode plants the
write and returns. Cleanup mode evicts /etc/passwd from page cache.
- _GNU_SOURCE redefine warning fixed: cmdline -D already passes it.
Verified end-to-end on kernel 6.12.86 (patched):
iamroot --scan → dirty_pipe reports OK (patched)
iamroot --exploit dirty_pipe --i-know → refuses cleanly
CI-validation against vulnerable kernel (Ubuntu 20.04 / 5.13) is Phase 4.
CVES.md: dirty_pipe 🔵 → 🟢. ROADMAP.md: Phase 2 marked complete.
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
