Vulnerability Details CVE-2026-45931

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Hold mm structure across iommu_sva_unbind_device() Some tests trigger a crash in iommu_sva_unbind_device() due to accessing iommu_mm after the associated mm structure has been freed. Fix this by taking an explicit reference to the mm structure after successfully binding the device, and releasing it only after the device is unbound. This ensures the mm remains valid for the entire SVA bind/unbind lifetime.
