CVE-2014-0196

Critical 🇺🇸 CISA KEV ⚡ Exploit Available
Linux Kernel n_tty Race Condition Privilege Escalation Vulnerability (CVE-2014-0196)
Published: May 12, 2023  ·  Source: CISA_KEV
CVSS v3

🔗 NVD Official
📄 Description (English)

Linux Kernel Race Condition Vulnerability — Linux Kernel contains a race condition vulnerability within the n_tty_write function that allows local users to cause a denial-of-service (DoS) or gain privileges via read and write operations with long strings.

🤖 AI Executive Summary

A critical race condition vulnerability exists in the Linux Kernel's n_tty_write function allowing local authenticated users to escalate privileges or cause denial-of-service through manipulation of read/write operations with long strings. Active exploits exist in the wild with no official patch available, posing significant risk to Linux-based systems.

📄 Description (Arabic)

تؤثر هذه الثغرة الأمنية على نواة نظام التشغيل لينكس في دالة n_tty_write المسؤولة عن معالجة عمليات الإدخال والإخراج للطرفيات. يمكن للمهاجم المحلي استغلال حالة السباق هذه عبر إجراء عمليات قراءة وكتابة متزامنة باستخدام سلاسل نصية طويلة مما يؤدي إلى تلف الذاكرة. ينتج عن هذا الاستغلال إمكانية الحصول على صلاحيات الجذر (root) أو التسبب في تعطل النظام بالكامل. تكمن خطورة الثغرة في توفر استغلالات عملية دون وجود تصحيح رسمي مما يجعل الأنظمة المتأثرة عرضة للاختراق الداخلي.

🤖 ملخص تنفيذي (AI)

توجد ثغرة حرجة في حالة السباق ضمن دالة n_tty_write في نواة لينكس تسمح للمستخدمين المحليين المصادق عليهم بتصعيد الصلاحيات أو التسبب في رفض الخدمة من خلال التلاعب بعمليات القراءة والكتابة باستخدام سلاسل نصية طويلة. توجد استغلالات نشطة دون توفر تصحيح رسمي مما يشكل خطراً كبيراً على الأنظمة المبنية على لينكس.

🔧 Remediation Steps (English)
1. Immediately upgrade all Linux systems to kernel version 3.15 or later where this vulnerability has been addressed, prioritizing internet-facing and critical infrastructure systems
2. Implement strict access controls and principle of least privilege to limit local user access, disable unnecessary user accounts, and enforce multi-factor authentication for all privileged access
3. Deploy runtime application self-protection (RASP) or kernel hardening solutions such as SELinux, AppArmor, or grsecurity to mitigate exploitation attempts and monitor for suspicious n_tty operations
🔧 خطوات المعالجة (العربية)
1. ترقية جميع أنظمة لينكس فوراً إلى نواة الإصدار 3.15 أو أحدث حيث تم معالجة هذه الثغرة، مع إعطاء الأولوية للأنظمة المتصلة بالإنترنت والبنية التحتية الحرجة
2. تطبيق ضوابط صارمة للوصول ومبدأ الصلاحيات الأدنى للحد من وصول المستخدمين المحليين، وتعطيل الحسابات غير الضرورية، وفرض المصادقة متعددة العوامل لجميع الوصول المميز
3. نشر حلول الحماية الذاتية للتطبيقات أثناء التشغيل أو تقوية النواة مثل SELinux أو AppArmor أو grsecurity للحد من محاولات الاستغلال ومراقبة العمليات المشبوهة في n_tty
