🔴 ★★★ 要対応 CVE


本日の要対応該当なし


期間内に KEV へ新しく追加された 4 件は、どれも主要製品ではありません(is_major_product=false)。そのため ★★★ の条件を満たす CVE はありません。

  • CVE-2026-76504 — Cisco Catalyst SD-WAN Manager (CVSS 9.8, KEV) : 認証なしでリモートから管理者権限を取られる可能性があります。原因は URI の hex エンコード処理です。自社では Cisco SD-WAN を基本的に使っていないため、影響は低いと考えられます。ただし、グループ会社や顧客環境の診断で見かけた場合は公式アドバイザリで確認してください。
  • CVE-2026-86950 — Apple iOS / macOS / iPadOS (CVSS 8.8, KEV) : CoreGraphics の境界外書き込みで、任意コードを実行される可能性があります。サーバ運用の対象外ですが、社員の端末(Mac / iPhone)は影響を受ける可能性があります。端末管理部門へ OS 更新の周知を検討してください。
  • CVE-2026-65660 — Microsoft SharePoint (CVSS 6.5, KEV) : 認証済みユーザーがコードを注入できる脆弱性です。CVSS は中程度ですが、悪用が確認されています。自社で SharePoint をオンプレ運用していなければ影響は低いと考えられます。M365 の SharePoint Online が対象かどうかは公式アドバイザリで確認してください。
  • CVE-2026-67279 — MikroTik RouterOS (CVSS 未評価, KEV) : 認証なしで exec 要求を送れる脆弱性です。CVE-2026-86060 と組み合わせて悪用される可能性があります。自社の運用対象外ですが、拠点や検証ネットワークで MikroTik 機器を使っていないか、念のため棚卸しを推奨します。


  • 📝 AI 全体サマリ

  • 全体トレンド: 今週新しく KEV に入ったのは 4 件で、ネットワーク機器(Cisco SD-WAN、MikroTik)、エンドユーザー OS(Apple)、グループウェア(SharePoint)でした。いずれも自社の主要 OSS スタックの対象外で、直ちにサーバ側で対応が必要なものは無い可能性が高いです。主要ソフトの更新は Ubuntu 24.04 のポイントリリースと Amazon Corretto 3 系統の定期更新です。
  • 特記事項(Ubuntu 24.04.5): cve_stats の数字(Critical 268 / KEV 40)は、2013〜2018 年の古い CVE を含む累積の集計とみられます。今回のリリースで新しく見つかった脆弱性の件数ではない可能性があります。still_vulnerable=0 なので、apt upgrade で最新パッケージに追従していれば大きな問題は無いと考えられます。カーネルや HWE スタックの更新を含む可能性があるので、再起動の要否と適用時期を計画してください。
  • 特記事項(Amazon Corretto 17 / 21 / 25): 既知 CVE の紐付けはありません。ただし、Oracle の四半期 CPU(Critical Patch Update)に連動した更新の可能性があります。Java を使っているサービス(Log4j 利用アプリなど)は、通常のリリースサイクルで更新すれば問題ないと考えられます。
  • PoC 検証: 主要製品に ★★★ 該当が無いため、本日は PoC 検証を推奨する CVE はありません。代わりに、Ubuntu 24.04.5 と Corretto 更新の互換性確認として、検証環境で次のような回帰テスト用の環境を作る案があります。

  • 
    # docker-compose.yml(骨子:更新後の互換性確認用)
    services:
      app-corretto21:
        image: amazoncorretto:21   # 更新後タグに置き換え
        volumes:
          - ./app:/app
        command: ["java", "-jar", "/app/app.jar"]
      base-ubuntu:
        image: ubuntu:24.04
        command: ["bash", "-c", "apt-get update && apt list --upgradable"]
    

  • 上記は互換性確認用の骨子です。exploit の検証を目的とするものではありません。
