    勘弁してほしい。OpenSSLのOCSPレスポンス検証で、クライアント側のメモリが漏れるCVE-2026-54876が公表された。暗号基盤の不具合は、アプリ単体ではなく認証・Proxy・監視まで組織横断で波及するのが厄介だ。 長時間稼働するプロセスでは、検証の積み重ねがメモリ枯渇や可用性低下につながる可能性がある。私の環境も、OpenSSLの直接利用だけでなく依存製品を含め、OCSP設定とプロセスのRSS推移を棚卸し対象に入れる。OpenSSLを内包する製品を資産台帳で追えていない組織、かなり危ない。#セキュリティ ソース: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-54876
