Published Jun 8, 2026

Updated

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

media: videobuf2: Set vmaflags in vb2dmasgmmap

vb2dmacontig sets VMA flags VMDONTEXPAND and VMDONTDUMP and I do not see a reason why vb2dmasg should behave differently. This avoids hitting WARNON(!(vma->vmflags & VMDONTEXPAND)); in drmgemmmapobj() during mmap() of an imported dma-buf from the out of tree Apple ISP camera capture driver which uses vb2dmasgmemops.
