📄 Description (English)

Mediatek Multiple Chipsets Insufficient Input Validation Vulnerability — Multiple MediaTek chipsets contain an insufficient input validation vulnerability and have missing SELinux restrictions in the Command Queue drivers ioctl handlers. This causes an out-of-bounds write leading to privilege escalation. This vulnerability was observed chained with CVE-2019-2215 and CVE-2020-0041 under exploit chain "AbstractEmu."

🤖 AI Executive Summary

MediaTek chipsets contain insufficient input validation in Command Queue drivers' ioctl handlers, enabling out-of-bounds writes and privilege escalation. This vulnerability was exploited in the AbstractEmu chain alongside other critical Android kernel vulnerabilities.

📄 Description (Arabic)

تحتوي معالجات MediaTek المتعددة على ثغرة في التحقق من صحة المدخلات في مشغلات Command Queue مع قيود SELinux مفقودة. تسمح هذه الثغرة بعمليات كتابة خارج الحدود تؤدي إلى تصعيد الامتيازات والتحكم الكامل بالجهاز. تم استغلالها بنجاح كجزء من سلسلة هجمات معقدة على أجهزة Android.

🤖 ملخص تنفيذي (AI)

معالجات MediaTek تحتوي على التحقق غير الكافي من المدخلات في معالجات ioctl لمشغلات قائمة الأوامر، مما يسمح بعمليات الكتابة خارج الحدود وتصعيد الامتيازات. تم استغلال هذه الثغرة في سلسلة AbstractEmu جنباً إلى جنب مع ثغرات نواة Android الحرجة الأخرى.
