Actions de réponse (7 étapes)

Étapes concrètes et exemples de commandes que les équipes SOC/SRE doivent exécuter dans l'ordre

1
Identify exposure identify
```
grep -r 'linux-hwe-edge' . | grep -v node_modules
```
リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で `linux-hwe-edge` を grep し、稼働しているサービス・バージョンを把握する。
6
Apply patch patch
```
Upgrade linux-hwe-edge to 5.15.0-1054.62~20.04.1
```
ステージング環境で 5.15.0-1054.62~20.04.1 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 3 で見つけた異常検知の続報チェックを含めること。
7
Post-deployment verification verify
```
Confirm patched version is live in production
```
パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 3 と同じログクエリでアラート再発が無いか継続監視。
