The README has been claiming "each module credits the original CVE
reporter and PoC author in its NOTICE.md" since v0.1.0, but only
copy_fail_family actually shipped one. Fixed.
modules/<name>/NOTICE.md (×19 new + 1 existing): per-module
research credit covering CVE ID, discoverer, original advisory
URL where public, upstream fix commit, IAMROOT's role.
iamroot.c: new --dump-offsets subcommand. Resolves kernel offsets
via the existing core/offsets.c four-source chain (env →
/proc/kallsyms → /boot/System.map → embedded table), then emits
a ready-to-paste C struct entry for kernel_table[]. Run once
as root on a target kernel build; upstream via PR. Eliminates
fabricating offsets — every shipped entry traces back to a
`iamroot --dump-offsets` invocation on a real kernel.
docs/OFFSETS.md: documents the --dump-offsets workflow.
CVES.md: notes the NOTICE.md convention + offset dump tool.
iamroot.c: bump IAMROOT_VERSION 0.3.0 → 0.3.1.

# NOTICE — pwnkit
|
|
|
|
## Vulnerability
|
|
|
|
**CVE-2021-4034** — pkexec argv[0]=NULL → environment-variable
|
|
injection → arbitrary code execution as root.
|
|
|
|
## Research credit
|
|
|
|
Discovered and disclosed by the **Qualys Research Team**, January 2022.
|
|
|
|
Original advisory:
|
|
<https://www.qualys.com/2022/01/25/cve-2021-4034/pwnkit.txt>
|
|
|
|
Upstream fix: polkit 0.121 (Jan 2022).
|
|
|
|
## IAMROOT role
|
|
|
|
The exploit module follows the canonical Qualys-style chain: writes
|
|
payload.c + gconv-modules cache, compiles via the target's gcc,
|
|
execve's pkexec with NULL argv and crafted envp. Handles both the
|
|
legacy ("0.105") and modern ("126") polkit version string formats.
|
|
Falls back gracefully on hosts without a compiler.
|
|
|
|
This is IAMROOT's first **userspace** LPE — not a kernel bug.
