CVE-2022-49426

CVE-2022-49426 : Linux kernel iommu/arm-smmu-v3-sva had a use-after-free when freeing the MM context because arm64_mm_context_put() ran without a held reference. The root cause is not holding a reference to the MM during unpinning, allowing it to be freed prematurely. The fix is to call mmgrab()/...
