📄 Description (English)

KissFFT before commit 8a8e66e contains an integer overflow vulnerability in the kiss_fftndr_alloc() function in kiss_fftndr.c where the allocation size calculation dimOther*(dimReal+2)*sizeof(kiss_fft_scalar) overflows signed 32-bit integer arithmetic before being widened to size_t, causing malloc() to allocate an undersized buffer. Attackers can trigger heap buffer overflow by providing crafted dimensions that cause the multiplication to exceed INT_MAX, allowing writes beyond the allocated buffer region when kiss_fftndr() processes the data.

🤖 AI Executive Summary

CVE-2026-41445 is a critical integer overflow vulnerability in KissFFT's kiss_fftndr_alloc() function that leads to heap buffer overflow. Attackers can craft malicious input dimensions to trigger undersized memory allocation, enabling arbitrary writes to heap memory. This vulnerability affects any Saudi organization using KissFFT for signal processing, audio/video applications, or scientific computing, with no patch currently available.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi telecommunications sector (STC, Mobily) using KissFFT for audio codec processing; healthcare institutions (MOH) employing signal processing for medical imaging; energy sector (ARAMCO, SEC) utilizing FFT for seismic/vibration analysis; financial institutions (SAMA-regulated banks) with audio/voice authentication systems; and government agencies (NCA, NCSC) processing classified signals. Remote code execution is possible if KissFFT processes untrusted input from network sources, potentially compromising critical infrastructure.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all systems and applications using KissFFT library (check build dependencies, linked libraries, embedded versions)
2. Isolate affected systems from untrusted input sources; restrict network access to KissFFT-dependent services
3. Implement input validation: enforce strict limits on dimension parameters (dimOther, dimReal) to prevent overflow conditions
4. Monitor heap memory corruption indicators (segmentation faults, unexpected process terminations)

PATCHING GUIDANCE:
1. Apply commit 8a8e66e or later from KissFFT repository when available
2. Implement custom fix: modify kiss_fftndr.c to use size_t for intermediate calculations or add overflow checks before malloc()
3. Recompile all dependent applications with patched KissFFT library

COMPENSATING CONTROLS (until patch available):
1. Implement strict input validation: validate dimension parameters against maximum safe values (INT_MAX / (2*sizeof(kiss_fft_scalar)))
2. Use memory protection mechanisms: enable ASLR, DEP/NX, stack canaries
3. Deploy application-level sandboxing for KissFFT processing
4. Implement rate limiting on FFT operations from untrusted sources

DETECTION RULES:
1. Monitor for malloc() calls with suspiciously small allocations followed by large write operations
2. Alert on heap corruption patterns or segmentation faults in KissFFT-dependent processes
3. Log dimension parameter values exceeding safe thresholds
4. Implement YARA rule: detect KissFFT library versions before commit 8a8e66e
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة والتطبيقات التي تستخدم مكتبة KissFFT (تحقق من تبعيات البناء والمكتبات المرتبطة والإصدارات المضمنة)
2. عزل الأنظمة المتأثرة عن مصادر الإدخال غير الموثوقة؛ تقييد الوصول إلى الشبكة للخدمات التابعة لـ KissFFT
3. تنفيذ التحقق من الإدخال: فرض حدود صارمة على معاملات الأبعاد (dimOther، dimReal) لمنع ظروف التجاوز
4. مراقبة مؤشرات تلف ذاكرة الكومة (أخطاء التجزئة، إنهاء العملية غير المتوقع)

إرشادات التصحيح:
1. تطبيق commit 8a8e66e أو إصدار أحدث من مستودع KissFFT عند توفره
2. تنفيذ إصلاح مخصص: تعديل kiss_fftndr.c لاستخدام size_t للحسابات الوسيطة أو إضافة فحوصات تجاوز قبل malloc()
3. إعادة ترجمة جميع التطبيقات التابعة باستخدام مكتبة KissFFT المصححة

الضوابط التعويضية (حتى توفر التصحيح):
1. تنفيذ التحقق الصارم من الإدخال: التحقق من معاملات الأبعاد مقابل القيم الآمنة القصوى
2. استخدام آليات حماية الذاكرة: تفعيل ASLR، DEP/NX، stack canaries
3. نشر الحماية على مستوى التطبيق لمعالجة KissFFT
4. تنفيذ تحديد معدل العمليات على مصادر غير موثوقة

قواعد الكشف:
1. مراقبة استدعاءات malloc() بتخصيصات صغيرة مريبة متبوعة بعمليات كتابة كبيرة
2. تنبيهات على أنماط تلف الكومة أو أخطاء التجزئة في العمليات التابعة لـ KissFFT
3. تسجيل قيم معاملات الأبعاد التي تتجاوز الحدود الآمنة
4. تنفيذ قاعدة YARA: الكشف عن إصدارات مكتبة KissFFT قبل commit 8a8e66e
