Two more famous LPEs broadening 'THE tool' coverage: af_packet CVE-2017-7308 (Andrey Konovalov, Mar 2017): - AF_PACKET TPACKET_V3 ring setup integer overflow → heap write-where - Fills 2017 coverage gap - kernel_range: 3.18.49 / 4.4.57 / 4.9.18 / 4.10.6 / mainline 4.11+ - Needs CAP_NET_RAW via user_ns clone - Famous as the canonical 'userns + AF_PACKET → root' research-era LPE fuse_legacy CVE-2022-0185 (William Liu / Crusaders-of-Rust, Jan 2022): - legacy_parse_param fsconfig heap OOB → cross-cache UAF → root - **Container-escape angle** — relevant to rootless docker/podman/snap (the system admin persona's nightmare) - kernel_range: 5.4.171 / 5.10.91 / 5.15.14 / 5.16.2 / mainline 5.17+ - Needs user_ns + mount_ns to reach legacy_load() code path - Originally reported as FUSE-specific but actually applies to any fs-mount path from userns (cgroup2, etc.) Both detect-only initially; full exploits in follow-ups.

# IAMROOT — top-level Makefile (Phase 1)

#
|
|
# Builds one binary `iamroot` linked from:
|
|
# - core/ module interface + registry
|
|
# - modules/<f>/ one family per subdir, contributes objects to the
|
|
# final binary
|
|
# - iamroot.c top-level dispatcher
|
|
#
|
|
# Each family is currently flat (Phase 1 keeps copy_fail_family's
|
|
# absorbed DIRTYFAIL source in modules/copy_fail_family/src/).
|
|
# Future families register the same way: add their register_* call to
|
|
# iamroot.c's main() and add their src dir to MODULE_DIRS below.
