# CVE-2026-68138 — Linux kernel net/sched qdisc rate-table UAF tracking site
Source for the **CVE-2026-68138** patch-status tracker: a single-page site
recording which distributions have shipped a fix for the `net/sched` qdisc
rate-table use-after-free / double-free in the Linux kernel.
## Where the facts live
Everything about the bug — the CVE ID, 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:
- **Rendered:**
- **Source:** [`site/content/_index.md`](site/content/_index.md)
Edit that file; everything else in this repo is build infrastructure.
None of it is restated here on purpose. The tracker page is revised as
distributions ship fixes — for the actively updated trackers, twice daily 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`](WEBSITE.md).
## Local development
Requires Hugo extended (≥ 0.146.0) and Go (for Hugo Modules to fetch the
PaperMod theme).
### With Nix (recommended)
```sh
nix develop # dev shell: hugo, go, git, resvg
cd site
hugo server # local preview at http://localhost:1313/CVE-2026-68138/
```
If you use [direnv](https://direnv.net/), `direnv allow` once and the dev
shell auto-activates whenever you `cd` into the repo.
### Without Nix
Install Hugo extended ≥ 0.146.0 and Go ≥ 1.24 yourself, then:
```sh
cd site
hugo server # http://localhost:1313/CVE-2026-68138/
```
## Build and publish
```sh
make build # local build into site/public/
make dist # build, then rsync to haig:/CVE-2026-68138/
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/cve-2026-68138-tracker.svg`; the rendered PNG is
committed.
