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.

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
