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

There is no remote or adjacent-network path to control DMA target addresses.\nAC:L - An attacker controlling a device behind the SMMU can deterministically generate a context fault by programming DMA to an IOVA that is not mapped, and the miscomputed container_of() offset is a fixed, unconditional error that fires every time the handler runs. No race or unpredictable precondition is involved.\nPR:L - Only ordinary local privileges are needed \u2014 a VFIO-assigned device handed to an unprivileged process or a guest VM, or a userspace-driven DMA engine on Tegra, is enough to provoke the fault; no root or CAP_SYS_ADMIN check exists on the fault-reporting path.\nUI:N - The attacker triggers the DMA fault directly; no action by any other user or administrator is required.\nS:U - The IOMMU still correctly blocks the offending DMA \u2014 the defect is in the fault-reporting handler \u2014 so both the vulnerable and impacted components are the host kernel with no crossing of a DMA or virtualization security boundary.\nC:H - The confused pointer is fetched from the adjacent heap object, and the resulting `bases[]` value is used as the base for readl/readq operations whose results (fsr, fsynr, iova, cbfrsynra) are printed to the kernel log, giving a groomable read primitive with disclosure of kernel memory contents.\nI:H - This is a type confusion in which a pointer field is taken from neighbouring heap memory and then used for register accesses including writel_relaxed(), so the kernel operates on and writes through an attacker-influenceable address.\nA:H - The dereference of the miscomputed pointer produces a fatal oops in hard IRQ context \u2014 as demonstrated by the reported NULL-pointer dereference at 0x120 on Jetson Orin NX \u2014 and can be triggered repeatedly, panicking the machine."
