medium Tenable Self-Hosted Container Security Plugin ID 463288

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. gst-launch-1.0 v4l2src ! gtk4paintablesink [ 38.201528] ------------[
