- dovecot 2.4.5（2026-08-28）は Critical 0 / High 4 で、最上位は CVE-2026-24031 (7.7) です。メールサービスを運用している場合はインターネット公開面に該当し得るため、次回メンテナンス枠での計画適用を推奨します。修正対象 CVE の一覧は公式リリースノートで確認してください。
- ubuntu 26.04.1（2026-08-28）はポイントリリースで High 1 件（CVE-2025-33208, 8.8）。EoL は 2031-04-30 と長く、LTS 移行計画には余裕がある状況です。
- CVE-2026-53362（Linux Kernel / IPv6 サブシステム経由の権限昇格の可能性）は EPSS 0.00265 と低いものの KEV 該当のため、Ubuntu 系ホストのカーネル ABI バージョンとベンダー提供の修正状況を確認しておくのが安全です。
- CVE-2019-1068（SQL Server）は matched_product が自社辞書にヒットしているため、実際に稼働インスタンスが存在するかどうかの確認を今週のタスクに入れることを推奨します。
