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().

CVE-2026-23429 CWE-364 kernel: iommu/sva: Fix crash in iommu_sva_unbind_device()
kernel: iommu/sva: Fix crash in iommu_sva_unbind_device()
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().
A flaw was found in the Linux kernel. Specifically, within the input/output memory management unit (IOMMU) subsystem, a memory management error can occur. When the `iommu_sva_unbind_device()` function is called, it may attempt to access a memory area that has already been freed
