Description

drm/mediatek: Clean dangling pointer on bind error path

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

drm/mediatek: Clean dangling pointer on bind error path

mtk_drm_bind() can fail, in which case drm_dev_put() is called,

destroying the drm_device object. However a pointer to it was still

being held in the private object, and that pointer would be passed along

to DRM in mtk_drm_sys_prepare() if a suspend were triggered at that

point, resulting in a panic. Clean the pointer when destroying the

object in the error path to prevent this from happening.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
