Descriptions
In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3-sva: Fix mm use-after-free We currently call arm64_mm_context_put() without holding a reference to
the mm, which can result in use-after-free. Call mmgrab()/mmdrop() to
ensure the mm only gets freed after we unpinned the ASID.
