In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-v3-sva: Fix mm use-after-free
We currently call arm64mmcontext_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.
