Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the videobuf2 component of the Linux kernel where the vb2 dma sg mmap() function fails to set the VM DONTEXPAND and VM DONTDUMP VMA flags. This inconsistency with vb2 dma contig can trigger a warning in the drm gem mmap obj() function during the mmap process of an imported dma-buf, specifically when using the Apple ISP camera capture driver which utilizes vb2 dma sg memops.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
