📄 Description (English)

When Bidirectional Forwarding Detection (BFD) is configured in Static and Dynamic routing protocols, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to stop processing BFD packets and cause the configured routing protocol to fail over.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

🤖 AI Executive Summary

CVE-2026-34019 affects BFD configuration in static and dynamic routing protocols, where undisclosed traffic causes the Traffic Management Microkernel to stop processing BFD packets, leading to routing protocol failover. This vulnerability impacts network availability and routing stability in affected systems.

📄 Description (Arabic)

تؤثر هذه الثغرة على أنظمة التوجيه التي تستخدم بروتوكول الكشف عن الأعطال ثنائي الاتجاه (BFD) مع البروتوكولات الثابتة والديناميكية. عندما تتلقى الأنظمة حركة مرور معينة غير مفصح عنها، يتوقف Traffic Management Microkernel عن معالجة حزم BFD بشكل صحيح. يؤدي هذا إلى فشل بروتوكول التوجيه المكون وقد يسبب انقطاعات في الخدمة.

🤖 ملخص تنفيذي (AI)

عندما يتم تكوين BFD في بروتوكولات التوجيه الثابتة والديناميكية، يمكن لحركة المرور غير المفصح عنها أن تتسبب في توقف Traffic Management Microkernel عن معالجة حزم BFD وفشل بروتوكول التوجيه المكون. تؤثر هذه الثغرة على توفر الشبكة واستقرار التوجيه في الأنظمة المتأثرة.

🔧 Remediation Steps (English)
Update affected systems to patched software versions that address BFD packet processing vulnerabilities. Verify routing protocol stability after updates and implement network monitoring to detect unexpected failover events. Organizations should prioritize systems still receiving technical support.
🔧 خطوات المعالجة (العربية)
تحديث الأنظمة المتأثرة إلى إصدارات برامج معالجة تعالج ثغرات معالجة حزم BFD. التحقق من استقرار بروتوكول التوجيه بعد التحديثات وتنفيذ مراقبة الشبكة للكشف عن أحداث الفشل غير المتوقعة. يجب على المنظمات إعطاء الأولوية للأنظمة التي لا تزال تتلقى الدعم الفني.
