  "details": "In the Linux kernel, the following vulnerability has been resolved:  iommu/tegra241-cmdqv: Require exactly one Stream ID for a vSID  tegra241_vintf_init_vsid() maps a guest vSID to a single physical Stream ID taken from master-\u003estreams[0], and only warns when the device does not have exactly one stream. A device with several streams gets only its first one mapped, so a guest vSID invalidation cannot reach the others' ATC and IOTLB entries; a device with none makes master-\u003estreams a ZERO_SIZE_PTR, read out of bounds.  Reject the mapping with -EOPNOTSUPP if master-\u003enum_streams is not one.",
