release v0.9.7: kernel_range drift fix + CI Node 24 readiness

Tags the maintenance work landed since v0.9.6. The fragnesia drift fix (35c33df) and checkout v4->v6 bump (6c148e2) are already on main; this commit adds the remaining CI Node-24 bumps + version strings. release.yml: upload-artifact v4->v7, download-artifact v4->v8, softprops/action-gh-release v2->v3 (last of the Node-20-era actions; GitHub forces node24 on 2026-06-16). Reviewed each changelog — our default-zip/unique-name upload + full-set download is unaffected by the major-version breaking changes (opt-in direct uploads, download-by-ID path). Version bumped to 0.9.7 (skeletonkey.c, README, docs/index.html) + v0.9.7 RELEASE_NOTES entry. Tagging this commit fires release.yml — the end-to-end test of the new artifact actions, incl. the Alpine/musl static job under node24.

+## SKELETONKEY v0.9.7 — kernel_range drift fix + CI Node 24 readiness
+
+Two maintenance fixes, no new modules.
+
+**`fragnesia` kernel_range drift.** Debian backported CVE-2026-46300 to
+the 5.10 oldstable branch (bullseye 5.10.257), a branch the module's
+`kernel_patched_from` table didn't model — on a patched bullseye host
+`detect()` would have false-positived VULNERABLE. Added the `{5,10,257}`
+entry; the weekly `refresh-kernel-ranges.py` drift gate is green again.
+(The other flagged modules are INFO-only "more permissive" thresholds
+the check tolerates by design.)
+
+**CI Node 24 readiness.** GitHub forces the Node 24 Actions runtime on
+2026-06-16 and removes Node 20. Bumped every workflow action off its
+Node-20 line:
+
+- `actions/checkout` v4 → v6
+- `actions/upload-artifact` v4 → v7
+- `actions/download-artifact` v4 → v8
+- `softprops/action-gh-release` v2 → v3
+
+Each was reviewed against its changelog: the artifact flow uploads
+default-zipped, uniquely-named artifacts and downloads the full set, so
+none of the major-version breaking changes (opt-in direct uploads,
+download-by-ID path changes) apply. This release is itself the
+end-to-end test of the new artifact actions.
+
+## SKELETONKEY v0.9.6 — `--auto` no longer prompts for sudo password
+
+Two sudo modules' `detect()` bodies invoked `sudo -ln` to read the
+user's allowed-commands list. The intent was non-interactive — `-ln`
+should parse as `-l -n` (list + non-interactive). But some sudoers /
+PAM configurations have been observed prompting for a password
+anyway when the flags are bundled, defeating the point.
+
+That meant `skeletonkey --auto --i-know` could hang on a sudo
+password prompt during the corpus scan, even though the whole point
+of an LPE tool is to *get* root without already having it.
+
+Fix in `sudo_runas_neg1` and `sudoedit_editor`:
+
+- `-n -l` written as separate flags (instead of bundled `-ln`)
+- `</dev/null` redirect so sudo cannot fall back to reading the tty
+  even if the PAM stack tries
+
+Belt-and-suspenders. `--auto` is now guaranteed never to block on
+tty input.
+
+---
+
+## SKELETONKEY v0.9.5 — kernel_range drift cleanup (the other half)
+
+v0.9.4 fixed the `cve_metadata` drift but exposed a *second* drift
+check (`kernel_range drift`) that had been hidden behind it. That
+check compares each module's `kernel_patched_from` table against
+Debian's security tracker. It had **11 TOO_TIGHT + 8 MISSING
+findings across 12 modules** — meaning `detect()` would have
+reported VULNERABLE on many kernels that Debian has on record as
+patched (false-positives), or missed branches entirely.
+
+Applied `tools/refresh-kernel-ranges.py --patch` recommendations
+across:
+
+- `cgroup_release_agent` — `{5,16,9}` → `{5,16,7}`
+- `cls_route4` — `{5,10,143}` → `{5,10,136}`, `{5,18,18}` → `{5,18,16}`
+- `dirty_cow` — `{4,7,10}` → `{4,7,8}`
+- `dirty_pipe` — `{5,10,102}` → `{5,10,92}`
+- `fragnesia` — `{6,12,91}` → `{6,12,90}`, `{7,0,10}` → `{7,0,9}`
+  (the 7.0.10 entry I added in v0.9.4 was an NVD-vs-Debian off-by-one)
+- `mutagen_astronomy` — added `{4,12,6}` backport entry
+- `netfilter_xtcompat` — `{5,10,46}` → `{5,10,38}`
+- `overlayfs_setuid` — `{6,1,27}` → `{6,1,11}`
+- `pintheft` — added `{6,12,90}` Debian-trixie entry
+- `ptrace_traceme` — `{4,19,58}` → `{4,19,37}`
+- `sequoia` — `{5,10,52}` → `{5,10,46}`
+- `tioscpgrp` — added `{5,9,15}` backport entry
+
+All changes are correctness-improving (no kernel that was previously
+flagged VULNERABLE-and-actually-vulnerable is now flagged OK; we just
+stop false-positiving on kernels that Debian has on record as patched).
+
+Build's `kernel_range drift` step now exits 0 with 0 TOO_TIGHT and 0
+MISSING.
+
+Also enabled `workflow_dispatch` on the build workflow so the
+drift-check job can be manually triggered without waiting for the
+weekly Monday-06:00-UTC cron.
+
+---
+
+## SKELETONKEY v0.9.4 — drift unblock, fragnesia range fix, infra docs
+
+Quality-of-life follow-ups from the v0.9.3 review:
+
+**Nightly CI drift-check unblocked.** v0.9.3's hand-applied
+`core/cve_metadata.c` entries weren't reflected in
+`docs/CVE_METADATA.json`, so the scheduled `build` workflow had
+been red since 2026-05-25 even though push-triggered runs passed.
+Regenerated both via the canonical script. Pintheft's CWE landed
+as CWE-787 (NVD-derived) — previously NULL.
+
+**fragnesia module range table corrected.** Same audit pattern that
+found the dirtydecrypt bug in v0.9.3. NVD CVE-2026-46300 confirms
+the SKBFL_SHARED_FRAG marker was introduced at 5.11 and the bug
+spans every stable branch since. Previous range table had one entry
+(`{7, 0, 9}`) — off-by-one against NVD's 7.0.10 fix point and
+missing every other backport. Now models 6 backports + predates-5.11
+introduction gate:
+
+```c
+{5, 15, 208}, /* 5.15-LTS */
+{6,  1, 174}, /* 6.1-LTS  */
+{6,  6, 141}, /* 6.6-LTS  */
+{6, 12,  91}, /* 6.12-LTS */
+{6, 18,  33}, /* 6.18-LTS */
+{7,  0,  10}, /* 7.0      */
+```
+
+Test row added for the predates path (kernel 4.4 → OK).
+
+**`tools/verify-vm/README.md` brought current.** The README was
+written for the v0.6-era apt-pin-only workflow. Now documents the
+v0.9.x infrastructure: mainline kernel pinning via
+kernel.ubuntu.com, per-module provisioners
+(`provisioners/<module>.sh`), two-phase prep→reboot→verify with
+post-reboot kernel confirmation, GRUB_DEFAULT pinning in both apt
+and mainline blocks.
+
+**NVD lookups in `refresh-cve-metadata.py` get a curl fallback.**
+v0.9.3 ran into Python's `urlopen` silently hanging on NVD's HTTP/2
+endpoint (55-min process with the 30s timeout never firing — kernel
+CLOSE_WAIT socket). The CISA path already had a curl fallback; the
+NVD path now mirrors it. Future runs degrade gracefully when
+urlopen wedges.

 ## Verification records

-`verify.sh` emits JSON on stdout after each run. Example:
+`verify.sh` appends one JSON record per run to
+`docs/VERIFICATIONS.jsonl`:

 ```json
 {
  "module":        "nf_tables",
-  "verified_at":   "2026-05-23T17:42:11Z",
-  "host_kernel":   "5.15.0-43-generic",

  "vm_box":        "generic/ubuntu2204",
  "expect_detect": "VULNERABLE",
  "actual_detect": "VULNERABLE",

+  "status":        "match"

 ```

 `status: match` means detect() returned what we expected on a known-
-vulnerable kernel. Anything else (`MISMATCH`, status code != 0) means

 ## How it routes module → box

 Mapping lives in `tools/verify-vm/targets.yaml`. Each entry has:

- `box` — which `boxes/` template (e.g. `ubuntu2204`)
- `kernel_pkg` — apt package name to install if the stock kernel
-  is patched (omit / empty if stock is already vulnerable)
+- `box` — generic/<distro> (e.g. `ubuntu2204`)
+- `kernel_pkg` — apt package for a vulnerable stock-archive kernel,
+  if one still exists in the distro's repos
+- `mainline_version` — alternative to `kernel_pkg`: pulls a vanilla
+  upstream kernel from `kernel.ubuntu.com/mainline/v<ver>/`. Use when
+  the apt-archive version has been garbage-collected (Ubuntu drops
+  old ABI versions) or when you need a specific point release that
+  the distro never packaged.
 - `kernel_version` — what `uname -r` should report after install
 - `expect_detect` — `VULNERABLE` | `OK` | `PRECOND_FAIL`
- `notes` — short rationale; comments in the file have the full context
+- `manual: true` — skip auto verification; explain why in `notes`
+- `notes` — full context for why this target was picked

-Adding a new module is one block in targets.yaml. The verifier picks
-it up automatically.
+Adding a new module is one block in targets.yaml. If the module needs
+per-target setup beyond installing a kernel — for example building
+sudo from source, adding a sudoers grant, or dropping a polkit allow
+rule — write a shell script at `tools/verify-vm/provisioners/<module>.sh`
+and the Vagrantfile will pick it up automatically.
+
+## Module-specific provisioners (`provisioners/<module>.sh`)
+
+When the kernel pin alone doesn't make a host vulnerable — e.g.
+the bug is sudo-version-gated, or a polkit "active session" check
+blocks the SSH path — drop a shell script at
+`tools/verify-vm/provisioners/<module_name>.sh`. The Vagrantfile
+runs it as root in the prep phase, before the `vagrant reload`
+check. Scripts should be idempotent (apt is no-op if installed,
+file overwrites are safe) since they re-run on every verify.
+
+Existing examples:
+
+- `sudo_chwoot.sh` — builds sudo 1.9.16p1 from upstream into
+  `/usr/local/bin` so the vulnerable `--chroot` code path is reachable
+  on Ubuntu 22.04 (which ships pre-feature 1.9.9).
+- `udisks_libblockdev.sh` — installs `udisks2` + drops a polkit rule
+  allowing the vagrant user to invoke `loop-setup` / `filesystem-mount`
+  (without this, the SSH session is not "active" per polkit and the
+  D-Bus call short-circuits).
+- `sudo_runas_neg1.sh` — adds `vagrant ALL=(ALL,!root) NOPASSWD: /bin/vi`
+  to `/etc/sudoers.d/` so `find_runas_blacklist_grant()` has a grant
+  to abuse.
+
+## Pinning kernels: apt vs mainline
+
+`pin-kernel-<pkg>` runs `apt-get install -y <pkg>`. Best when the
+target version still lives in the distro's archive (rare for old
+point releases — Ubuntu eventually GCs them). Also pins `GRUB_DEFAULT`
+to the just-installed kernel so the reboot lands on it instead of
+the higher-version stock kernel.
+
+`pin-mainline-<ver>` downloads vanilla mainline debs from
+`kernel.ubuntu.com/mainline/v<ver>/`. Tries `/amd64/` first, falls
+back to bare `/v<ver>/` for old kernels (≤ ~4.15) where amd64 wasn't
+a separate subdir. Accepts both `linux-image-` (older naming) and
+`linux-image-unsigned-` (current). Pins `GRUB_DEFAULT` to the
+mainline kernel so grub doesn't keep booting the higher-versioned
+stock kernel.

Reviewed each changelog — our default-zip/unique-name upload + full-set download is unaffected by the major-version breaking changes (opt-in direct uploads, download-by-ID path). Version bumped to 0.9.7 (skeletonkey.c, README, docs/index.html) + v0.9.7 RELEASE_NOTES entry. Tagging this commit fires release.yml — the end-to-end test of the new artifact actions, incl. the Alpine/musl static job under node24.	2026-06-01 11:55:31 -04:00

All 9 usages (5 in build.yml, 4 in release.yml) are bare checkouts with no inputs, so the major bump is a drop-in.

Adding {5,10,257} clears the only MISSING finding; refresh-kernel-ranges.py now exits 0.

Some sudoers / PAM configurations have been observed prompting for a password anyway when the flags are bundled. That meant skeletonkey --auto --i-know could hang on a sudo password prompt during the corpus scan — bad ergonomics for an LPE tool whose whole point is to get root without already having it. Fix: write '-n -l' as separate flags, redirect stdin from /dev/null so sudo cannot fall back to reading the tty even if PAM tries to coerce one. Belt-and-suspenders against any tty prompt during --auto.	2026-05-28 21:50:26 -04:00

All changes are strictly correctness-improving: detect() now correctly returns OK on kernels Debian has on record as patched, instead of false-positiving VULNERABLE. The biggest single fix is reverting fragnesia from {7,0,10} (NVD) to {7,0,9} (Debian's backported fix). I introduced that off-by-one in v0.9.4 from misreading NVD's versionEndExcluding semantics.

Per NVD: bug entered at 5.11 SKBFL_SHARED_FRAG, vulnerable through 5.15.207 / 6.1.173 / 6.6.140 / 6.12.90 / 6.18.32 / 7.0.9, fixed at .208/.174/.141/ .91/.33/.10. Prior table had one entry {7,0,9} — off-by-one and missing every other backport. Added predates-5.11 introduction gate + test row. - Update tools/verify-vm/README.md to document the v0.9.x infra: mainline kernel pinning via kernel.ubuntu.com, per-module provisioner hooks, two-phase prep→reboot→verify with post-reboot kernel confirmation, GRUB_DEFAULT pinning. - Add curl fallback for NVD lookups in refresh-cve-metadata.py. Mirrors the CISA path's existing fallback. Prevents the silent Python urlopen hang seen during v0.9.3 prep (55-min stuck on CLOSE_WAIT socket; 30s timeout never fired).	2026-05-28 13:33:28 -04:00
