Doc Text:
A flaw was found in the Linux kernel's `media: mtk-mdp` module. A reference leak occurs because the `vpu_get_plat_device()` function increases a reference count that is not properly decreased by `platform_device_put()` in `mtk_mdp_remove()`. This issue could potentially lead to resource exhaustion over time, which may result in a Denial of Service (DoS) for the system.

Description OSIDB Bzimport 2026-05-06 13:06:00 UTC 
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.
