  "details": "In the Linux kernel, the following vulnerability has been resolved:  iommu/sva: Set handle-\u003edev before the SVA handle is visible  iommu_attach_device_pasid() installs the new SVA attach handle in the group PASID lookup before iommu_sva_bind_device() returns. A concurrent bind can therefore find and reuse the same handle after iommu_sva_lock is dropped.  handle-\u003edev was initialized after dropping iommu_sva_lock. This leaves a window where a racing bind can return a handle whose dev pointer is still NULL. A subsequent iommu_sva_unbind_device() can then dereference it via handle-\u003edev-\u003eiommu_group.  Initialize handle-\u003edev before releasing iommu_sva_lock so any visible SVA handle is fully initialized.",
