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

drm/mediatek: Set private->all_drm_private[i]->drm to NULL if mtk_drm_bind returns err

The pointer need to be set to NULL, otherwise KASAN complains about use-after-free. Because in mtk_drm_bind, all private's drm are set as follows.

private->all_drm_private[i]->drm = drm;

And drm will be released by drm_dev_put in case mtk_drm_kms_init returns failure. However, the shutdown path still accesses the previous allocated memory in drm_atomic_helper_shutdown.
