📄 Description (English)
Memory Corruption when handling power management requests with improperly sized input/output buffers.
🤖 AI Executive Summary
CVE-2026-21382 is a high-severity memory corruption vulnerability (CVSS 7.8) affecting multiple Qualcomm firmware components used in power management subsystems. The vulnerability stems from improper buffer size validation in power management request handlers, potentially allowing local attackers to trigger memory corruption and achieve privilege escalation or denial of service. With no patch currently available, this poses an immediate risk to devices using affected Qualcomm chipsets across Saudi Arabia's critical infrastructure.

🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all devices using affected Qualcomm firmware (Cologne, FastConnect 6900/7800, SC8380XP, WCD series, WSA series)
2. Isolate or restrict network access to devices in critical infrastructure until patches are available
3. Implement enhanced monitoring for power management subsystem anomalies
4. Disable unnecessary power management features where operationally feasible
Compensating Controls:
1. Deploy application-level input validation for power management requests
2. Implement memory protection mechanisms (ASLR, DEP/NX) at OS level
3. Use SELinux/AppArmor policies to restrict power management daemon privileges
4. Monitor system logs for memory corruption indicators (segmentation faults, kernel panics)
5. Implement network segmentation to limit lateral movement from compromised devices
Detection Rules:
1. Alert on unexpected power management request patterns or malformed buffer sizes
2. Monitor for privilege escalation attempts following power management operations
3. Track kernel memory corruption events and unexpected process terminations
4. Implement firmware integrity verification mechanisms
Patching Strategy:
1. Subscribe to Qualcomm security bulletins for patch availability
2. Establish expedited testing and deployment procedures for firmware updates
3. Prioritize patching for devices in SAMA-regulated and NCA-critical environments
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حصر جميع الأجهزة التي تستخدم البرامج الثابتة المتأثرة من Qualcomm (Cologne, FastConnect 6900/7800, SC8380XP, سلسلة WCD, سلسلة WSA)
2. عزل أو تقييد الوصول إلى الشبكة للأجهزة في البنية التحتية الحرجة حتى توفر التصحيحات
3. تنفيذ مراقبة محسّنة لشذوذ نظام إدارة الطاقة
4. تعطيل ميزات إدارة الطاقة غير الضرورية حيث يكون ذلك ممكناً من الناحية التشغيلية
الضوابط البديلة:
1. نشر التحقق من صحة المدخلات على مستوى التطبيق لطلبات إدارة الطاقة
2. تنفيذ آليات حماية الذاكرة (ASLR, DEP/NX) على مستوى نظام التشغيل
3. استخدام سياسات SELinux/AppArmor لتقييد امتيازات خدمة إدارة الطاقة
4. مراقبة سجلات النظام للكشف عن مؤشرات فساد الذاكرة (أخطاء التجزئة، توقف النواة)
5. تنفيذ تقسيم الشبكة لتحديد الحركة الجانبية من الأجهزة المخترقة
قواعد الكشف:
1. تنبيهات على أنماط طلبات إدارة الطاقة غير المتوقعة أو أحجام المخزن المؤقت المشوهة
2. مراقبة محاولات تصعيد الامتيازات بعد عمليات إدارة الطاقة
3. تتبع أحداث فساد ذاكرة النواة وإنهاء العمليات غير المتوقعة
4. تنفيذ آليات التحقق من سلامة البرامج الثابتة
استراتيجية التصحيح:
1. الاشتراك في نشرات أمان Qualcomm لتوفر التصحيحات
2. إنشاء إجراءات اختبار ونشر معجلة لتحديثات البرامج الثابتة
3. أولويات التصحيح للأجهزة في البيئات المنظمة من قبل SAMA والحرجة من قبل NCA
