📄 Description (English)

In the Linux kernel, the following vulnerability has been resolved:

media: mtk-mdp: Fix a reference leak bug in mtk_mdp_remove()

In mtk_mdp_probe(), vpu_get_plat_device() increases the reference
count of the returned platform device. Add platform_device_put()
to prevent reference leak.

🤖 AI Executive Summary

A reference leak vulnerability exists in the Linux kernel's MTK MDP media driver where vpu_get_plat_device() increases reference counts without proper cleanup in mtk_mdp_remove(). This can lead to resource exhaustion and potential denial of service on affected systems.

📄 Description (Arabic)

تم اكتشاف تسرب مرجع في برنامج تشغيل وسائط MTK MDP بنواة Linux حيث لا تقوم دالة mtk_mdp_remove() باستدعاء platform_device_put() لتنظيف جهاز المنصة. يمكن أن يؤدي هذا إلى استنزاف الموارد والخدمة المرفوضة على الأنظمة المتأثرة.
