📄 Description (English)

Transient DOS when processing a malformed Fast Transition response frame with an invalid header structure during wireless roaming.

🤖 AI Executive Summary

CVE-2025-47403 is a medium-severity denial-of-service vulnerability affecting wireless roaming implementations through malformed Fast Transition response frames. The vulnerability causes transient service disruption when processing frames with invalid header structures, potentially impacting enterprise wireless networks. While no public exploit exists and patches are unavailable, the attack requires network proximity and specific frame crafting, limiting immediate threat severity.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: May 11, 2026 07:37
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations operating enterprise wireless networks face transient service disruptions, particularly affecting: banking sector (SAMA-regulated institutions relying on secure wireless for branch operations), government agencies (NCA, CITC infrastructure), healthcare facilities (MOH hospitals with wireless patient monitoring), telecommunications providers (STC, Mobily, Zain with extensive WiFi networks), and energy sector (ARAMCO facilities with industrial wireless systems). The impact is primarily operational availability rather than data breach, but affects critical service continuity.

🔧 Remediation Steps (English)
Immediate Actions:
1. Monitor wireless network logs for malformed Fast Transition (FT) response frames and unusual roaming failures
2. Implement wireless intrusion detection system (WIDS) rules to detect and alert on malformed FT frames
3. Restrict Fast Transition protocol usage to trusted networks only where possible
4. Disable 802.11r (Fast Roaming) on non-critical wireless networks until patches available

Compensating Controls:
1. Implement rate limiting on FT response frame processing at access point level
2. Deploy wireless network segmentation to isolate critical services from affected roaming zones
3. Configure access points to drop malformed frames rather than process them
4. Enable detailed wireless logging and monitoring for anomalous roaming patterns
5. Implement network access control (NAC) to restrict device roaming behavior

Detection Rules:
1. Alert on FT response frames with invalid header length fields
2. Monitor for repeated roaming failures from same source MAC address
3. Track access point crashes or resets correlated with wireless traffic spikes
4. Log and analyze frames with malformed RSNE (Robust Security Network Element) in FT context
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. مراقبة سجلات الشبكة اللاسلكية للبحث عن إطارات استجابة انتقال سريع مشوهة وفشل التجوال غير المعتاد
2. تنفيذ قواعد نظام كشف الاختراق اللاسلكي للكشف والتنبيه عن الإطارات المشوهة
3. تقييد استخدام بروتوكول الانتقال السريع للشبكات الموثوقة فقط حيث أمكن
4. تعطيل 802.11r (التجوال السريع) على الشبكات اللاسلكية غير الحرجة حتى توفر التصحيحات

الضوابط البديلة:
1. تنفيذ تحديد معدل معالجة إطارات استجابة FT على مستوى نقطة الوصول
2. نشر تقسيم الشبكة اللاسلكية لعزل الخدمات الحرجة عن مناطق التجوال المتأثرة
3. تكوين نقاط الوصول لإسقاط الإطارات المشوهة بدلاً من معالجتها
4. تفعيل السجلات اللاسلكية المفصلة والمراقبة للأنماط غير الطبيعية
5. تنفيذ التحكم في الوصول إلى الشبكة للتحكم في سلوك التجوال

قواعد الكشف:
1. التنبيه على إطارات استجابة FT برؤوس طول غير صحيحة
2. مراقبة فشل التجوال المتكرر من نفس عنوان MAC المصدر
3. تتبع أعطال أو إعادة تعيين نقاط الوصول المرتبطة بارتفاعات حركة المرور اللاسلكية
4. تسجيل وتحليل الإطارات برؤوس مشوهة في سياق FT
