      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/tegra241-cmdqv: Reject a vSID wider than the SID_MATCH field\n\ntegra241_vintf_init_vsid() programs the guest-provided vSID into SID_MATCH,\nwhose VIRT_SID field spans bits [20:1] with bit 0 as the match-enable flag.\nThe HW therefore matches only a 20-bit Stream ID.\n\nThe bound check rejects only virt_sid > UINT_MAX, which admits a value far\nwider than the field. The write \"virt_sid << 1 | 0x1\" then drops every bit\nabove 20: a virt_sid of 0x80000000 lands as SID_MATCH = 0x1, a valid match\non vSID 0, so the entry aliases the wrong Stream ID. Because vdev->virt_id\nis guest-controlled, a VMM can trigger it.\n\nValidate virt_sid against the field width with FIELD_MAX(), and program the\nregister with FIELD_PREP() so the value and the field stay consistent.",
