CVE-2024-36884 (2024)
In the Linux kernel, the following vulnerability has been resolved:

iommu/arm-smmu: Use the correct type in nvidia_smmu_context_fault()

This was missed because of the function pointer indirection.

nvidia_smmu_context_fault() is also installed as a irq function, and the
'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain
is embedded at a non-zero offset this causes nvidia_smmu_context_fault()
to miscompute the offset. Fixup the types.
