Breaking change. Tool name, binary name, function/type names,
constant names, env vars, header guards, file paths, and GitHub
repo URL all rebrand IAMROOT → SKELETONKEY.
Changes:
- All "IAMROOT" → "SKELETONKEY" (constants, env vars, enum
values, docs, comments)
- All "iamroot" → "skeletonkey" (functions, types, paths, CLI)
- iamroot.c → skeletonkey.c
- modules/*/iamroot_modules.{c,h} → modules/*/skeletonkey_modules.{c,h}
- tools/iamroot-fleet-scan.sh → tools/skeletonkey-fleet-scan.sh
- Binary "iamroot" → "skeletonkey"
- GitHub URL KaraZajac/IAMROOT → KaraZajac/SKELETONKEY
- .gitignore now expects build output named "skeletonkey"
- /tmp/iamroot-* tmpfiles → /tmp/skeletonkey-*
- Env vars IAMROOT_MODPROBE_PATH etc. → SKELETONKEY_*
New ASCII skeleton-key banner (horizontal key icon + ANSI Shadow
SKELETONKEY block letters) replaces the IAMROOT banner in
skeletonkey.c and README.md.
VERSION: 0.3.1 → 0.4.0 (breaking).
Build clean on Debian 6.12.86. `skeletonkey --version` → 0.4.0.
All 24 modules still register; no functional code changes — pure
rename + banner refresh.

NOTICE — nf_tables (CVE-2024-1086)
Vulnerability
CVE-2024-1086 — nft_verdict_init double-free → cross-cache UAF
→ arbitrary kernel R/W.
Research credit
Discovered, exploited, and disclosed by Notselwyn (Pumpkin), January 2024.
Original advisory + exploit: https://pwning.tech/nftables/ GitHub: https://github.com/Notselwyn/CVE-2024-1086
Upstream fix: mainline 6.8-rc1 (commit f342de4e2f33, Jan 2024).
Stable backports throughout Q1 2024.
SKELETONKEY role
This module fires the malformed-verdict trigger (NFT_GOTO + NFT_DROP
in the same verdict) via a hand-rolled nfnetlink batch — no libmnl
dependency. The msg_msg cross-cache groom into kmalloc-cg-96 is wired
but the full pipapo R/W stage is opt-in via --full-chain, which
forges a pipapo_elem with a value-pointer pointing at modprobe_path.
Per-kernel offset assumptions are documented; the shared finisher's
sentinel arbitrates real vs. apparent success.
