- core/kernel_range.{c,h}: branch-aware patched-version comparison.
Every future module needs 'is the host kernel in the affected
range?'; centralized here. Models stable-branch backports
(e.g. 5.10.102, 5.15.25) so a 5.15.20 host correctly reports
VULNERABLE while a 5.15.50 host reports OK.
- modules/dirty_pipe_cve_2022_0847/ (promoted out of _stubs):
- iamroot_modules.{c,h}: dirty_pipe module exposing detect() that
parses /proc/version and compares against the four known patched
branches (5.10.102, 5.15.25, 5.16.11, 5.17+ inherited). Returns
IAMROOT_OK / IAMROOT_VULNERABLE / IAMROOT_TEST_ERROR with stderr
hints in human-readable scan mode.
- exploit() returns IAMROOT_PRECOND_FAIL with a 'not yet
implemented' message; landing the actual exploit needs Phase 1.5
extraction of passwd/su helpers into core/.
- detect/auditd.rules: splice() syscall + passwd/shadow file watches
- detect/sigma.yml: non-root modification of /etc/passwd|shadow|sudoers
- iamroot.c main() calls iamroot_register_dirty_pipe() alongside
the copy_fail_family registration.
- Makefile gains the dirty_pipe family as a separate object set.
Verified end-to-end on kctf-mgr (kernel 6.12.86): build clean, 6
modules in --list, --scan correctly reports dirty_pipe as patched,
JSON output ingest-ready.

# Roadmap
|
|
|
|
What's coming next, in priority order. Dates are aspirational, not
|
|
commitments.
|
|
|
|
## Phase 0 — Bootstrap (DONE as of 2026-05-16)
|
|
|
|
- [x] Repo structure (modules/, core/, docs/, tools/, tests/)
|
|
- [x] Absorbed DIRTYFAIL as the first module
|
|
(`modules/copy_fail_family/`)
|
|
- [x] Top-level README, CVES.md, ROADMAP.md, docs/ARCHITECTURE.md,
|
|
docs/ETHICS.md
|
|
- [x] LICENSE (MIT)
|
|
- [x] Private GitHub repo
|
|
|
|
## Phase 1 — Make the bundling real (DONE 2026-05-16)
|
|
|
|
- [x] Top-level `iamroot` dispatcher CLI (`iamroot.c`) — module
|
|
registry, route to module's detect/exploit
|
|
- [x] Module interface header (`core/module.h`) — standard
|
|
`iamroot_module` struct + `iamroot_result_t` (numerically
|
|
aligned with copy_fail_family's `df_result_t` for zero-cost
|
|
bridging)
|
|
- [x] `core/registry.{c,h}` — flat-array registry with `find_by_name`
|
|
- [x] `modules/copy_fail_family/iamroot_modules.{c,h}` — bridge layer
|
|
exposing 5 modules
|
|
- [x] Top-level `Makefile` that builds all modules into one binary
|
|
- [x] Smoke test: `iamroot --scan --json` produces ingest-ready JSON;
|
|
`iamroot --list` prints the module inventory
|
|
- [ ] **Deferred to Phase 1.5**: extract `apparmor_bypass.c`,
|
|
`exploit_su.c`, `common.c`, `fcrypt.c` into `core/` (shared
|
|
across families). Phase 1 keeps them inside copy_fail_family/src/
|
|
because there's only one family today; the extraction is
|
|
mechanical and lands when a second family arrives.
|
|
|
|
## Phase 2 — Add Dirty Pipe (CVE-2022-0847) — PARTIAL (DETECT done 2026-05-16)
|
|
|
|
Public PoC, well-understood, useful for completeness — IAMROOT
|
|
without Dirty Pipe is incomplete as a "historical bundle." Affects
|
|
kernels ≤5.16.11/≤5.15.25/≤5.10.102 so coverage is older
|
|
deployments (worth bundling — many production boxes still run
|
|
these).
|
|
|
|
- [x] `modules/dirty_pipe_cve_2022_0847/` directory promoted out of
|
|
`_stubs/`
|
|
- [x] `core/kernel_range.{c,h}` — branch-aware patched-version
|
|
comparison (reusable by every future module)
|
|
- [x] `dirty_pipe_detect()` — kernel version check against
|
|
branch-backport thresholds (5.10.102 / 5.15.25 / 5.16.11 / 5.17+)
|
|
- [x] Detection rules: `auditd.rules` (splice() syscall + passwd/shadow
|
|
watches) and `sigma.yml` (non-root modification of sensitive files)
|
|
- [x] Registered in `iamroot --list` / `--scan` output. Verified on
|
|
kernel 6.12.86 → correctly reports OK (patched).
|
|
- [ ] **Phase 1.5 / Phase 2 followup**: actual exploit. Needs
|
|
extraction of `find_passwd_uid_field` + `try_revert_passwd_page_cache`
|
|
+ `exploit_su` into `core/` so dirty_pipe can call them without
|
|
duplicating the copy_fail_family helpers.
|
|
- [ ] CI matrix: Ubuntu 20.04 with kernel 5.13 (vulnerable),
|
|
Debian 11 with 5.10.0-8 (vulnerable), Debian 13 with 6.12.x
|
|
(patched — should detect as OK)
|
|
|
|
## Phase 3 — Add EntryBleed (CVE-2023-0458) as stage-1 leak brick
|
|
|
|
EntryBleed is **not a standalone LPE**. It's a **kbase leak
|
|
primitive** that other modules can chain. Bundle it because:
|
|
|
|
- Stage-1 of any future "build-your-own LPE" workflow
|
|
- Detection rules for KPTI side-channel attempts are useful for
|
|
defenders
|
|
- Already works empirically on lts-6.12.88 (verified 2026-05-16)
|
|
|
|
- [ ] `modules/entrybleed_cve_2023_0458/` — leak primitive +
|
|
detect-mitigations
|
|
- [ ] Exposed as a library helper: other modules can call
|
|
`entrybleed_leak_kbase()` when they need a kbase
|
|
|
|
## Phase 4 — CI matrix
|
|
|
|
- [ ] Distro+kernel VM matrix in GitHub Actions (Ubuntu 20.04 /
|
|
22.04 / 24.04 / 26.04, Debian 11 / 12 / 13, Alma 8 / 9 / 10,
|
|
Fedora 39 / 40 / 41)
|
|
- [ ] Each module's exploit runs against matched-vulnerable VMs and
|
|
MUST land root; runs against patched VMs and MUST fail at
|
|
detect step
|
|
- [ ] Nightly run; failures open issues automatically
|
|
|
|
## Phase 5 — Detection signature export
|
|
|
|
- [ ] `iamroot --detect-rules --format=sigma` — Sigma rules per CVE
|
|
- [ ] `--format=yara` — YARA rules for static detection of exploit
|
|
binaries
|
|
- [ ] `--format=auditd` — auditd `.rules` snippets
|
|
- [ ] `--format=falco` — Falco rule snippets
|
|
- [ ] Sample SOC playbook in `docs/DETECTION_PLAYBOOK.md`
|
|
|
|
## Phase 6 — Mitigation mode
|
|
|
|
- [ ] `iamroot --mitigate` walks the host's vulnerabilities, applies
|
|
temporary sysctl / module-blacklist / LSM workarounds
|
|
- [ ] Per-CVE rollback procedure if the mitigation breaks something
|
|
- [ ] Idempotent: running twice is safe
|
|
|
|
## Phase 7+ — More modules
|
|
|
|
Backfill of historical and recent LPEs as time allows:
|
|
|
|
- [ ] **CVE-2021-3493** — overlayfs nested-userns LPE
|
|
- [ ] **CVE-2021-4034** — Pwnkit (pkexec env handling)
|
|
- [ ] **CVE-2022-2588** — net/sched route4 dead UAF
|
|
- [ ] **CVE-2023-2008** — vmwgfx OOB write
|
|
- [ ] **CVE-2024-1086** — netfilter nf_tables UAF
|
|
- [ ] Fragnesia (if it lands as a CVE)
|
|
- [ ] Anything we ourselves disclose — bundled AFTER upstream patch
|
|
ships (responsible-disclosure-first)
|
|
|
|
## Non-goals
|
|
|
|
- **No 0-day shipment.** Everything in IAMROOT is post-patch.
|
|
- **No automated mass-targeting.** No host-list mode. No automatic
|
|
pivoting.
|
|
- **No persistence beyond `--exploit-backdoor`'s
|
|
`/etc/passwd` overwrite**, which is overt and easily detected by
|
|
any auditd rule we ship ourselves. Persistence-as-evasion is out
|
|
of scope.
|
|
- **No container-runtime escapes** unless they cleanly chain to
|
|
host-root.
|
|
- **No Windows / macOS / non-Linux targets.** Focus is the moat.
