📄 Description (English)

Out-of-bounds read in Windows NTFS allows an authorized attacker to elevate privileges locally.

🤖 AI Executive Summary

CVE-2026-25175 is a high-severity out-of-bounds read vulnerability in Windows NTFS affecting multiple Windows 10 versions. An authorized local attacker can exploit this flaw to elevate privileges, potentially gaining system-level access. While no public exploit is currently available, the vulnerability requires immediate patching across all affected Windows 10 builds to prevent privilege escalation attacks in Saudi organizations.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability poses significant risk to Saudi government agencies, banking sector (SAMA-regulated institutions), healthcare facilities, and critical infrastructure operators relying on Windows 10 systems. Government entities using Windows 10 for administrative functions face elevated risk of insider threats and privilege escalation attacks. Banking and financial institutions are particularly vulnerable as compromised workstations could lead to unauthorized access to sensitive financial systems. Energy sector organizations and telecommunications providers (STC) managing critical infrastructure must prioritize patching to prevent lateral movement within their networks.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all Windows 10 systems across affected versions (1607, 1809, 21H2, 22H2) in your organization
2. Prioritize patching for systems with high-privilege user accounts and administrative access
3. Restrict local administrative access and enforce principle of least privilege
4. Monitor for suspicious privilege escalation attempts in security logs

PATCHING GUIDANCE:
1. Apply Microsoft security updates immediately upon availability through Windows Update or WSUS
2. Test patches in non-production environments before enterprise deployment
3. Prioritize patching for domain-joined systems and servers first
4. Ensure all Windows 10 versions (1607, 1809, 21H2, 22H2) receive updates

COMPENSATING CONTROLS (if patching delayed):
1. Disable NTFS access for non-administrative users where operationally feasible
2. Implement application whitelisting to prevent unauthorized privilege escalation tools
3. Enable Windows Defender Exploit Guard and Attack Surface Reduction rules
4. Enforce multi-factor authentication for administrative accounts
5. Implement file integrity monitoring on critical NTFS volumes

DETECTION RULES:
1. Monitor Event ID 4688 (Process Creation) for suspicious NTFS-related system calls
2. Alert on unexpected privilege elevation attempts (Event ID 4672)
3. Monitor for unusual file system access patterns and NTFS metadata modifications
4. Track failed and successful privilege escalation attempts in Windows Security logs
5. Implement EDR solutions to detect out-of-bounds memory access patterns
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع أنظمة Windows 10 في الإصدارات المتأثرة (1607، 1809، 21H2، 22H2) في مؤسستك
2. أعط الأولوية لتصحيح الأنظمة ذات حسابات المستخدمين عالية الامتيازات والوصول الإداري
3. قيد الوصول الإداري المحلي وفرض مبدأ أقل امتياز
4. راقب محاولات الارتقاء بالامتيازات المريبة في سجلات الأمان

إرشادات التصحيح:
1. طبق تحديثات أمان Microsoft فوراً عند توفرها عبر Windows Update أو WSUS
2. اختبر التصحيحات في بيئات غير الإنتاج قبل نشرها على مستوى المؤسسة
3. أعط الأولوية لتصحيح الأنظمة المرتبطة بالمجال والخوادم أولاً
4. تأكد من حصول جميع إصدارات Windows 10 (1607، 1809، 21H2، 22H2) على التحديثات

الضوابط البديلة (إذا تأخر التصحيح):
1. عطل وصول NTFS للمستخدمين غير الإداريين حيث يكون ذلك ممكناً من الناحية التشغيلية
2. طبق قائمة بيضاء للتطبيقات لمنع أدوات الارتقاء بالامتيازات غير المصرح بها
3. فعّل Windows Defender Exploit Guard وقواعد تقليل سطح الهجوم
4. فرض المصادقة متعددة العوامل لحسابات المسؤولين
5. طبق مراقبة سلامة الملفات على أحجام NTFS الحرجة

قواعد الكشف:
1. راقب معرف الحدث 4688 (إنشاء العملية) لاستدعاءات نظام NTFS المريبة
2. أصدر تنبيهات لمحاولات الارتقاء بالامتيازات غير المتوقعة (معرف الحدث 4672)
3. راقب أنماط الوصول غير العادية لنظام الملفات وتعديلات بيانات تعريف NTFS
4. تتبع محاولات الارتقاء بالامتيازات الفاشلة والناجحة في سجلات أمان Windows
5. طبق حلول EDR للكشف عن أنماط الوصول إلى الذاكرة خارج الحدود
