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

media: videobuf2: Set vma_flags in vb2_dma_sg_mmap

vb2_dma_contig sets VMA flags VM_DONTEXPAND and VM_DONTDUMP and I do not see a reason why vb2_dma_sg should behave differently. This avoids hitting WARN_ON(!(vma->vm_flags & VM_DONTEXPAND)); in drm_gem_mmap_obj() during mmap() of an imported dma-buf from the out of tree Apple ISP camera capture driver which uses vb2_dma_sg_memops.
