CVE-2026-74573
In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3-iommufd: Require exactly one Stream ID for a vDEVICE armvsmmuvsidtosid maps a guest's vSID to a single physical Stream ID taken from master-streams0, assuming a device has exactly one stream. A device with sever...
CVE-2026-74573
CVE-2026-74573 affects the Linux kernel IOMMU arm-smmu-v3-iommufd code. The vulnerability arises because arm_vsmmu_vsid_to_sid() maps a guest vSID to a single physical Stream ID taken from master->streams[0], implicitly assuming exactly one stream per device. If a device has multiple streams, ...

CVE-2026-43130
The CVE-2026-43130 issue affects the Linux kernel iommu/vt-d path, where flushing the dev-IOTLB can occur during resource release in scalable PCIe mode. The root cause is a path that attempted ATS invalidation without adequately verifying whether the PCIe device is still accessible after a link-d...
