Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iommu: Fix two issues in iommu_copy_struct_from_user()<br /> <br /> In the review for iommu_copy_struct_to_user() helper, Matt pointed out that<br /> a NULL pointer should be rejected prior to dereferencing it:<br /> https://lore.kernel.org/all/86881827-8E2D-461C-BDA3-FA8FD14C343C@nvidia.com<br /> <br /> And Alok pointed out a typo at the same time:<br /> https://lore.kernel.org/all/480536af-6830-43ce-a327-adbd13dc3f1d@oracle.com<br /> <br /> Since both issues were copied from iommu_copy_struct_from_user(), fix them<br /> first in the current header.
