{"id":"DEBIAN-CVE-2024-36884","details":"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.
