CVE-2026-23429

Published: April 3, 2026· Updated: Apr 7, 2026

EPSS:0.02%probability of exploitation in 30 daysPercentile:4.0th

Official Description

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().
