📄 Description (English)

Use after free in Windows Kernel allows an authorized attacker to elevate privileges locally.

🤖 AI Executive Summary

CVE-2026-24289 is a use-after-free vulnerability in the Windows Kernel affecting multiple Windows 10 versions that allows authorized local attackers to elevate privileges. With a CVSS score of 7.8 and no public exploit currently available, this vulnerability poses a significant risk to Saudi organizations relying on Windows infrastructure. Immediate patching is critical to prevent privilege escalation attacks that could compromise system integrity and sensitive data access.

📄 Description (Arabic)

🤖 AI Intelligence Analysis Analyzed: Apr 29, 2026 04:55
🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi government agencies, banking sector (SAMA-regulated institutions), healthcare organizations, and large enterprises running Windows 10 across their infrastructure. Government entities under NCA oversight and financial institutions under SAMA supervision face elevated risk due to the privilege escalation potential. Energy sector organizations (ARAMCO, utilities) and telecommunications providers (STC, Mobily) with Windows-based operational technology and administrative systems are particularly vulnerable. The vulnerability could enable insider threats or compromised user accounts to gain system-level access, potentially leading to data exfiltration, system compromise, and regulatory violations.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all Windows 10 systems across the organization, prioritizing critical infrastructure and systems handling sensitive data
2. Apply Microsoft security patches immediately upon availability through Windows Update or WSUS
3. Restrict local administrative access and enforce principle of least privilege for all user accounts
4. Monitor for suspicious privilege escalation attempts in Windows Event Logs (Event ID 4688, 4689, 4703)

PATCHING GUIDANCE:
1. Deploy patches to Windows 10 versions 1607, 1809, 21H2, and 22H2 (all architectures: x86, x64, ARM64)
2. Test patches in non-production environments before enterprise deployment
3. Prioritize patching for systems with high-value data or critical operations
4. Establish a 30-day patching SLA for this vulnerability

COMPENSATING CONTROLS (if patching delayed):
1. Implement application whitelisting to restrict unauthorized code execution
2. Enable Windows Defender Exploit Guard and Attack Surface Reduction rules
3. Enforce multi-factor authentication for all administrative accounts
4. Disable unnecessary services and kernel drivers to reduce attack surface
5. Implement kernel patch protection (KPP/Device Guard) where available

DETECTION RULES:
1. Monitor Windows Event Log for use-after-free kernel exceptions (Event ID 1001 in System log)
2. Alert on unexpected kernel mode code execution from user-mode processes
3. Track failed and successful privilege escalation attempts (Event ID 4673)
4. Monitor for suspicious driver loading and kernel object manipulation
5. Implement EDR solutions to detect abnormal kernel-level activity patterns
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع أنظمة Windows 10 في المنظمة، مع إعطاء الأولوية للبنية التحتية الحرجة والأنظمة التي تتعامل مع البيانات الحساسة
2. طبق تصحيحات الأمان من Microsoft فورًا عند توفرها عبر Windows Update أو WSUS
3. قيد الوصول الإداري المحلي وفرض مبدأ أقل امتياز لجميع حسابات المستخدمين
4. راقب محاولات رفع الامتيازات المريبة في سجلات أحداث Windows (معرف الحدث 4688، 4689، 4703)

إرشادات التصحيح:
1. نشر التصحيحات لإصدارات Windows 10 1607 و1809 و21H2 و22H2 (جميع الهندسات: x86 و x64 و ARM64)
2. اختبر التصحيحات في بيئات غير الإنتاج قبل النشر على مستوى المؤسسة
3. أعط الأولوية لتصحيح الأنظمة التي تحتوي على بيانات عالية القيمة أو عمليات حرجة
4. ضع اتفاقية مستوى الخدمة لمدة 30 يومًا لتصحيح هذه الثغرة

الضوابط البديلة (إذا تأخر التصحيح):
1. طبق قائمة بيضاء للتطبيقات لتقييد تنفيذ الأكواد غير المصرح بها
2. فعّل Windows Defender Exploit Guard وقواعد تقليل سطح الهجوم
3. فرض المصادقة متعددة العوامل لجميع الحسابات الإدارية
4. عطّل الخدمات والمشغلات غير الضرورية لتقليل سطح الهجوم
5. طبق حماية التصحيح النواة (KPP/Device Guard) حيث يكون متاحًا

قواعد الكشف:
1. راقب سجل أحداث Windows للاستثناءات النواة من نوع use-after-free (معرف الحدث 1001 في سجل النظام)
2. أصدر تنبيهات لتنفيذ الأكواس في وضع النواة غير المتوقع من عمليات وضع المستخدم
3. تتبع محاولات رفع الامتيازات الفاشلة والناجحة (معرف الحدث 4673)
4. راقب تحميل المشغلات المريبة ومعالجة كائنات النواة
5. طبق حلول EDR للكشف عن أنماط نشاط النواة غير الطبيعية
