UBUNTU-CVE-2022-42720 (linux-hwe-edge) — 攻撃ベクター: ローカル / 被害者操作不要修正バージョン: `5.4.0-1088.96~18.04.1` (即時適用推奨) 対応方針: 1) SBOMで影響バージョン横断確認, 2) ステージング検証→本番更新, 3) WAF/プロキシで該当エンドポイントを監視, 4) ログでIOC調査。参考: 当ページの『参照URL』の GHSA / vendor advisory / patched release を参照。

❓ 何が問題か

linux-hwe-edge に **脆弱性** (分類未定) があります。

📍 影響範囲

linux-hwe-edge のうち。

🔥 重要度

重要度: ?。悪用されるとシステム全体を乗っ取られる可能性があります

🔧 修正方法

**5.4.0-1088.96~18.04.1** に更新してください。

🛡️ 暫定回避

修正版が未提供時は、影響機能の無効化・WAFルール・ネットワークACLでの遮断を検討。

🔍 検知方法

Webサーバ・プロキシ・WAFログで該当CVEのIOCに合致する不審リクエストを検索。SBOM/依存ファイルで影響バージョンを横断確認。

対応アクション (7段階)

SOC/SREチームが順番に実行すべき具体的なステップとコマンド例

1
影響範囲の特定 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
パッチ適用 patch
```
Upgrade linux-hwe-edge to 5.4.0-1088.96~18.04.1
```
ステージング環境で 5.4.0-1088.96~18.04.1 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
事後検証 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。
