suominen/ghostlockTracking GhostLock (CVE-2026-43499), the rtmutex/futex stack use-after-free
Source for the GhostLock patch-status tracker: a single-page site recording which distributions have shipped a fix for the rtmutex/futex stack use-after-free in the Linux kernel.
Tracking concluded 2026-08-06: every tracked kernel carries the fix, so the page is frozen and the scheduled auto-update is unwired. The site stays published as a record.
Everything about the bug — CVE IDs, affected and fixed versions, upstream fix commits, discovery and disclosure credit, and current per-distribution patch status — belongs to the tracker page, not to this README:
site/content/_index.mdEdit that file; everything else in this repo is build infrastructure.
None of it is restated here on purpose. The tracker page is revised as CVEs are assigned and distributions ship fixes — for the actively updated trackers, on a schedule by the auto-update agent — so any copy kept in this README would silently rot. Resist re-adding a summary.
Deployment plan and current setup state live in
WEBSITE.md.
Requires Hugo extended (≥ 0.146.0) and Go (for Hugo Modules to fetch the PaperMod theme).
nix develop # dev shell: hugo, go, git, resvg
cd site
hugo server # local preview at http://localhost:1313/ghostlock/
If you use direnv, direnv allow once and the dev
shell auto-activates whenever you cd into the repo.
Install Hugo extended ≥ 0.146.0 and Go ≥ 1.24 yourself, then:
cd site
hugo server # http://localhost:1313/ghostlock/
make build # local build into site/public/
make dist # build, then rsync to haig:/ghostlock/
make banner # re-rasterise the social banner SVG → PNG (needs resvg + Roboto)
make dist runs make build first. make banner is only needed after
editing site/assets/ghostlock-tracker.svg; the rendered PNG is committed.
