展開して表示 (3件)

CVE-2026-86950 — Apple Multiple Products (iOS / macOS / iPadOS) (CVSS 8.8, KEV) : CoreGraphics の境界外書き込みで、任意コード実行につながる可能性があります。サーバ運用対象ではないため自社影響は低いと考えられます。ただし社用の Mac や iPhone が端末管理の対象に含まれる場合は、OS 更新が届いているか端末管理側で確認することを推奨します。

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脆弱性です。CVSS は中程度ですが、KEV 登録のため実際に悪用されている可能性があります。自社では SharePoint を運用していないため影響は低いと考えられます。オンプレミスの SharePoint Server が社内に残っていないかだけ確認してください。

CVE-2026-67279 — MikroTik RouterOS (CVSS 未算出, KEV) : 認証なしのクライアントがセッションチャネルを開き、exec 要求を送れる可能性がある脆弱性です。CVE-2026-86060 と連鎖させると、認証なしでの悪用につながる可能性があります。自社の運用対象外のため影響は低いと考えられます。拠点や検証環境で MikroTik 機器を使っている場合は、公式アドバイザリで修正版を確認してください。

全体トレンド: 今週（2026-09-24〜09-30）の KEV 追加は 3 件です。対象はクライアント OS（Apple）、コラボレーション基盤（SharePoint）、ネットワーク機器（MikroTik）で、どれも自社の主要運用対象外でした。主要ソフトの更新は Amazon Corretto 17 / 21 / 25 の同日リリースのみで、紐付いた CVE は 0 件です。全体として、自社への直接影響は小さい週だったと考えられます。

特記事項:

- Amazon Corretto の 3 系列が同時に更新されています。データ上の CVE は 0 件ですが、上流の OpenJDK の修正を取り込んでいる可能性があります。修正内容は公式リリースノートで確認し、通常のパッチサイクルで計画的に適用するのが妥当と考えられます。

- MikroTik の CVE-2026-67279 は、別の CVE（CVE-2026-86060）との連鎖が前提とされています。CVSS が未算出なので、今後スコアが付いて評価が変わる可能性があります。

- Firefox 157.0 は非主要製品です。社内端末の標準ブラウザであれば、端末管理の通常更新で追従すれば十分と考えられます。

PoC 検証の推奨: 今回は主要製品で PoC 検証が必要と考えられる CVE はありません。検証環境の構築案は省略します。
