leviathan f03efbff13 Phase 3: EntryBleed module — working stage-1 kbase leak brick
- modules/entrybleed_cve_2023_0458/ (promoted out of _stubs):
  - iamroot_modules.{c,h}: full EntryBleed primitive (rdtsc_start/end
    + prefetchnta + KASLR-slot timing sweep) wired into the standard
    iamroot_module interface. x86_64 only; ARM/other gracefully
    return IAMROOT_PRECOND_FAIL.
  - detect(): reads /sys/.../vulnerabilities/meltdown to decide
    KPTI status. Mitigation: PTI → VULNERABLE. Not affected → OK.
  - exploit(): sweeps the 16MiB KASLR range, prints leaked kbase
    (and KASLR slide). JSON-mode emits {"kbase":"0x..."} to stdout.
  - entrybleed_leak_kbase_lib(off) declared as a public library
    helper so future LPE chains needing a stage-1 leak can just
    #include the module's header and call it.
  - entry_SYSCALL_64 slot offset overridable via
    IAMROOT_ENTRYBLEED_OFFSET (default 0x5600000 for lts-6.12.x).

- __always_inline fallback added since glibc/Linux-kernel macro
  isn't universal; module now builds clean under macOS clangd lint
  and on musl.

- iamroot.c registers entrybleed alongside the other families;
  Makefile gains it as a separate object set.

Verified end-to-end on kctf-mgr (Debian 6.12.86):
  iamroot --exploit entrybleed --i-know
  → [+] entrybleed: leaked kbase = 0xffffffff8d800000

This is the FIRST WORKING-EXPLOIT module in IAMROOT (5
copy_fail_family modules wrap existing code from DIRTYFAIL;
dirty_pipe is detect-only). EntryBleed is x86_64 stage-1 brick
that future chains can compose.

Roadmap

What's coming next, in priority order. Dates are aspirational, not commitments.

Phase 0 — Bootstrap (DONE as of 2026-05-16)

  • Repo structure (modules/, core/, docs/, tools/, tests/)
  • Absorbed DIRTYFAIL as the first module (modules/copy_fail_family/)
  • Top-level README, CVES.md, ROADMAP.md, docs/ARCHITECTURE.md, docs/ETHICS.md
  • LICENSE (MIT)
  • Private GitHub repo

Phase 1 — Make the bundling real (DONE 2026-05-16)

  • Top-level iamroot dispatcher CLI (iamroot.c) — module registry, route to module's detect/exploit
  • 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)
  • core/registry.{c,h} — flat-array registry with find_by_name
  • modules/copy_fail_family/iamroot_modules.{c,h} — bridge layer exposing 5 modules
  • Top-level Makefile that builds all modules into one binary
  • 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).

  • modules/dirty_pipe_cve_2022_0847/ directory promoted out of _stubs/
  • core/kernel_range.{c,h} — branch-aware patched-version comparison (reusable by every future module)
  • dirty_pipe_detect() — kernel version check against branch-backport thresholds (5.10.102 / 5.15.25 / 5.16.11 / 5.17+)
  • Detection rules: auditd.rules (splice() syscall + passwd/shadow watches) and sigma.yml (non-root modification of sensitive files)
  • 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 — EntryBleed (CVE-2023-0458) as stage-1 leak brick (DONE 2026-05-16)

EntryBleed is not a standalone LPE. It's a kbase leak primitive that other modules can chain. Bundled 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

  • Exposed as a library helper: other modules can call entrybleed_leak_kbase_lib() (declared in iamroot_modules.h)

  • Wired into iamroot.c registry; iamroot --exploit entrybleed --i-know produces a kbase leak. Verified on kctf-mgr: leaked 0xffffffff8d800000 with KASLR slide 0xc800000.

  • entry_SYSCALL_64 slot offset configurable via IAMROOT_ENTRYBLEED_OFFSET env var (default matches lts-6.12.x). Future enhancement: auto-detect via /boot/System.map or /proc/kallsyms if accessible.

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.
