展開して表示 (4件)
  • 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 の SD-WAN を基本的に使っていないため、影響は低いと見られます。ただし、グループ会社や委託先で使っていないかは確認したほうがよい可能性があります。
  • CVE-2026-86950 — Apple iOS / macOS / iPadOS (CoreGraphics) (CVSS 8.8, KEV):境界外書き込みにより、任意のコードを実行される可能性があります。サーバ側の運用対象ではないため、直接の影響は低いと見られます。ただし、社用の Mac や iPhone については、端末管理チームによる OS 更新の徹底を推奨します。修正バージョンは公式アドバイザリで確認してください。
  • CVE-2026-65660 — Microsoft SharePoint (CVSS 6.5, KEV):認証済みの攻撃者がネットワーク経由でコードを注入できる可能性があります。CVSS は中程度ですが、実際の悪用が確認されています。自社の運用対象外のため影響は低いと見られますが、社内で SharePoint Server をオンプレで運用していないかは確認する価値があります。
  • CVE-2026-67279 — MikroTik RouterOS (CVSS 未評価, KEV):認証なしでセッションチャネルを開き、exec 要求を送れる可能性があります。CVE-2026-86060 と組み合わせると、認証なしで悪用される可能性が指摘されています。自社の主要運用対象ではありませんが、拠点や検証環境に小型ルータとして置かれていることがあるため、棚卸しを推奨します。


  • 📝 AI 全体サマリ

  • 全体トレンド:今週の KEV 追加は、SD-WAN やルータなどのネットワーク境界機器(Cisco / MikroTik)と、エンドポイント・グループウェア製品(Apple / SharePoint)が中心です。境界機器で認証なしにリモートから悪用できる脆弱性が、引き続き狙われている傾向がうかがえます。自社の主要運用対象である OSS(nginx / Django / Next.js / PostgreSQL / Log4j 等)では、新しく KEV に追加されたものはありません。
  • Ubuntu 24.04.5 について:表の CVE 件数(Critical 268 / KEV 40)は、CVE-2013 や CVE-2014 のような古いものまで含めた製品全体の累計と見られます。still_vulnerable=0 なので、今回のポイントリリースで新しいリスクが生じたわけではない可能性が高いです。状態は機械的に「⚠️要確認」になっていますが、実際の対応としては、通常の apt upgrade によるパッケージ更新計画で足りる可能性があります。カーネルの更新や HWE スタックの変更を含むかどうかは、公式のリリースノートで確認してください。
  • Amazon Corretto 17 / 21 / 25 について:Oracle の四半期 CPU に合わせた定例更新と見られます。CVE 件数は 0 と集計されていますが、Java SE 側の CPU で修正された CVE が含まれている可能性があります。Corretto 公式のリリースノートで確認し、計画的に適用することを推奨します。
  • 特記事項:CVE-2026-67279(MikroTik)は CVSS が未評価です。CVE-2026-86060 と組み合わせた攻撃が報告されているため、スコアが付いたあとで再評価が必要になる可能性があります。
  • PoC 検証:今回は主要製品で ★★★ に該当するものがないため、PoC 検証を急ぐ CVE はありません。Ubuntu 24.04.5 への更新による影響を事前に見たい場合は、次の骨子で回帰確認環境を作ることが考えられます。
