NASA CryptoLib KMC Client Unbounded Memory Allocation Vulnerability (CVE-2026-22026)
CWE-789 — Weakness Type

🔗 NVD Official
📄 Description (English)

CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the libcurl write_callback function in the KMC crypto service client allows unbounded memory growth by reallocating response buffers without any size limit or overflow check. A malicious KMC server can return arbitrarily large HTTP responses, forcing the client to allocate excessive memory until the process is terminated by the OS. This issue has been patched in version 1.4.3.

🤖 AI Executive Summary

CVE-2026-22026 is a memory exhaustion vulnerability in CryptoLib's KMC crypto service client that allows unbounded buffer reallocation without size limits. A malicious KMC server can force excessive memory allocation, causing denial of service by exhausting system resources.

📄 Description (Arabic)

تحتوي دالة write_callback في عميل خدمة التشفير KMC على ثغرة تسمح بنمو الذاكرة غير المحدود عند إعادة تخصيص مخازن مؤقتة للاستجابة دون حدود أو فحوصات تجاوز. يمكن لخادم KMC ضار إرجاع استجابات HTTP كبيرة بشكل تعسفي، مما يفرض على العميل تخصيص ذاكرة مفرطة حتى يتم إنهاء العملية من قبل نظام التشغيل.

🤖 ملخص تنفيذي (AI)

This vulnerability affects spacecraft communication security systems used in satellite operations and ground station infrastructure. Organizations managing space-based communications or satellite systems should update CryptoLib to version 1.4.3 or later.

🔧 Remediation Steps (English)
Upgrade CryptoLib to version 1.4.3 or later immediately. Implement network segmentation to restrict KMC server communications. Deploy memory usage monitoring and process limits. Validate HTTP response sizes before processing. Conduct security audit of all spacecraft communication systems.
🔧 خطوات المعالجة (العربية)
قم بترقية CryptoLib إلى الإصدار 1.4.3 أو أحدث فوراً. طبق تقسيم الشبكة لتقييد اتصالات خادم KMC. نشر مراقبة استخدام الذاكرة وحدود العمليات. تحقق من أحجام استجابات HTTP قبل المعالجة. أجر تدقيق أمني شامل لجميع أنظمة الاتصالات الفضائية.
