leviathan d84b3b0033 release v0.9.0: 5 gap-fillers — every year 2016 → 2026 now covered 
Five new modules close the 2018 gap entirely and thicken
2019 / 2020 / 2024. All five carry the full 4-format detection-rule
corpus + opsec_notes + arch_support + register helpers.

CVE-2018-14634 — mutagen_astronomy (Qualys, closes 2018)
  create_elf_tables() int wrap → SUID-execve stack corruption.
  CISA KEV-listed Jan 2026 despite the bug's age; legacy RHEL 7 /
  CentOS 7 / Debian 8 fleets still affected. 🟡 PRIMITIVE.
  arch_support: x86_64+unverified-arm64.

CVE-2019-14287 — sudo_runas_neg1 (Joe Vennix)
  sudo -u#-1 → uid_t underflow → root despite (ALL,!root) blacklist.
  Pure userspace logic bug; the famous Apple Information Security
  finding. detect() looks for a (ALL,!root) grant in sudo -ln output;
  PRECOND_FAIL when no such grant exists for the invoking user.
  arch_support: any (4 -> 5 userspace 'any' modules).

CVE-2020-29661 — tioscpgrp (Jann Horn / Project Zero)
  TTY TIOCSPGRP ioctl race on PTY pairs → struct pid UAF in
  kmalloc-256. Affects everything through Linux 5.9.13. 🟡 PRIMITIVE
  (race-driver + msg_msg groom). Public PoCs from grsecurity /
  spender + Maxime Peterlin.

CVE-2024-50264 — vsock_uaf (a13xp0p0v / Pwnie Award 2025 winner)
  AF_VSOCK connect-race UAF in kmalloc-96. Pwn2Own 2024 + Pwnie
  2025 winner. Reachable as plain unprivileged user (no userns
  required — unusual). Two public exploit paths: @v4bel+@qwerty
  kernelCTF (BPF JIT spray + SLUBStick) and Alexander Popov / PT
  SWARM (msg_msg). 🟡 PRIMITIVE.

CVE-2024-26581 — nft_pipapo (Notselwyn II, 'Flipping Pages')
  nft_set_pipapo destroy-race UAF. Sibling to nf_tables
  (CVE-2024-1086) from the same Notselwyn paper. Distinct bug in
  the pipapo set substrate. Same family signature. 🟡 PRIMITIVE.

Plumbing changes:

  core/registry.h + registry_all.c — 5 new register declarations
    + calls.
  Makefile — 5 new MUT/SRN/TIO/VSK/PIP module groups in MODULE_OBJS.
  tests/test_detect.c — 7 new test rows covering the new modules
    (above-fix OK, predates-the-bug OK, sudo-no-grant PRECOND_FAIL).
  tools/verify-vm/targets.yaml — verifier entries for all 5 with
    honest 'expect_detect' values based on what Vagrant boxes can
    realistically reach (mutagen_astronomy gets OK on stock 18.04
    since 4.15.0-213 is post-fix; sudo_runas_neg1 gets PRECOND_FAIL
    because no (ALL,!root) grant on default vagrant user; tioscpgrp
    + nft_pipapo VULNERABLE with kernel pins; vsock_uaf flagged
    manual because vsock module rarely available on CI runners).
  tools/refresh-cve-metadata.py — added curl fallback for the CISA
    KEV CSV fetch (urlopen times out intermittently against CISA's
    HTTP/2 endpoint).

Corpus growth across v0.8.0 + v0.9.0:

                v0.7.1    v0.8.0    v0.9.0
  Modules          31        34        39
  Distinct CVEs    26        29        34
  KEV-listed       10        10        11 (mutagen_astronomy)
  arch 'any'        4         6         7 (sudo_runas_neg1)
  Years 2016-2026:  10/11     10/11     **11/11**

Year-by-year coverage:

  2016: 1   2017: 1   2018: 1   2019: 2   2020: 2
  2021: 5   2022: 5   2023: 8   2024: 3   2025: 2   2026: 4

CVE-2018 gap → CLOSED. Every year from 2016 through 2026 now has
at least one module.

Surfaces updated:
  - README.md: badge → 22 VM-verified / 34, Status section refreshed
  - docs/index.html: hero eyebrow + footer → v0.9.0, hero tagline
    'every year 2016 → 2026', stats chips → 39 / 22 / 11 / 151
  - docs/RELEASE_NOTES.md: v0.9.0 entry added on top with year
    coverage matrix + per-module breakdown; v0.8.0 + v0.7.1 entries
    preserved below
  - docs/og.svg + og.png: regenerated with new numbers + 'Every
    year 2016 → 2026' tagline

CVE metadata refresh (tools/refresh-cve-metadata.py) deferred to
follow-up — CISA KEV CSV + NVD CVE API were timing out during the
v0.9.0 push window. The 5 new CVEs will return NULL from
cve_metadata_lookup() until the refresh runs (—module-info simply
skips the WEAKNESS/THREAT INTEL header for them; no functional
impact). Re-run 'tools/refresh-cve-metadata.py' when network
cooperates.

Tests: macOS local 33/33 kernel_range pass; detect-test stubs (88
total) build clean; ASan/UBSan + clang-tidy CI jobs still green
from the v0.7.x setup.
