Doc Text:
A flaw was found in the Linux kernel's `mtk-mdp` media driver. Improper error handling in the probe function could lead to a resource leak. Additionally, a missing check for the return value of `vpu_get_plat_device()` could result in a null pointer dereference, potentially causing a system crash and leading to a denial of service.

Description OSIDB Bzimport 2026-05-06 13:08:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: mtk-mdp: Fix error handling in probe function

Add mtk_mdp_unregister_m2m_device() on the error handling path to prevent
resource leak.

Add check for the return value of vpu_get_plat_device() to prevent null
pointer dereference. And vpu_get_plat_device() increases the reference
count of the returned platform device. Add platform_device_put() to
prevent reference leak.
