fkie_cve-2026-23429

In the Linux kernel, the following vulnerability has been resolved:

iommu/sva: Fix crash in iommu_sva_unbind_device()

domain->mm->iommu_mm can be freed by iommu_domain_free(): iommu_domain_free() mmdrop() __mmdrop() mm_pasid_drop() After iommu_domain_free() returns, accessing domain->mm->iommu_mm may dereference a freed mm structure, leading to a crash.

Fix this by moving the code that accesses domain->mm->iommu_mm to before the call to iommu_domain_free().
