  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/amd: Bound the early ACPI HID map\n\nThe ivrs_acpihid command-line parser appends entries to a fixed\nfour-element early_acpihid_map array. Unlike the sibling IOAPIC and HPET\nparsers, it does not reject a fifth entry before incrementing the map size.\n\nCheck the capacity at the common found label before parsing the HID and\nUID or writing the entry.",
