Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A reference leak exists in the Linux kernel within the mtk-mdp media component. The vpu get plat device() function, called during mtk mdp probe(), increases the reference count of the returned platform device, but this count is not properly decreased in mtk mdp remove(), leading to a leak.

Recommendations Add the platform device put() function to mtk mdp remove() to ensure the platform device reference count is correctly decremented.
