There are two issues in vmw_kms_update_layout_ioctl(). First, the for loop forgets to index rects and only checks the first element. Second, there is a potential integer overflow if userspace passes in a large arg->num_outputs. The call to kzalloc() would allocate a small buffer, leading to out-of-bounds read.
