# Dirty Frag — kernel page-cache write tracking site

Patch-status tracker for the **Dirty Frag** Linux kernel local privilege
escalation, a chain of two page-cache write vulnerabilities (xfrm-ESP and
RxRPC) discovered by [Hyunwoo Kim (@v4bel)](https://github.com/V4bel/dirtyfrag).
No CVE has been assigned at the time of this writing.

The rendered site is published at ****.
Deployment plan and current setup state live in [`WEBSITE.md`](WEBSITE.md).

## Source of truth

The tracker is a single Hugo page: [`site/content/_index.md`](site/content/_index.md).
Edit that file; everything else is build infrastructure.

## Local development

Requires Hugo extended (≥ 0.146.0) and Go (for Hugo Modules to fetch the
PaperMod theme).

### With Nix (recommended)

```sh
nix develop          # shell with hugo + go + git (pinned by flake.lock once generated)
cd site
hugo server          # local preview at http://localhost:1313/CVE-2026-43284/
```

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-2026-43284/
```

## Build and publish

```sh
make build       # local build into site/public/
make dist        # build, then rsync to haig:.www/sites/kimmo.cloud/htdocs/CVE-2026-43284/
```

`make dist` runs `make build` first.
