Vulnerability Title
drm/mediatek: Set private->all_drm_private[i]->drm to NULL if mtk_drm_bind returns err
来源: CVE Program / CVE List V5
Vulnerability Description
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.
