Title
iommu/amd: Bound the early ACPI HID map
Summary
In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Bound the early ACPI HID map The ivrs_acpihid command-line parser appends entries to a fixed four-element early_acpihid_map array. Unlike the sibling IOAPIC and HPET parsers, it does not reject a fifth entry before incrementing the map size. Check the capacity at the common found label before parsing the HID and UID or writing the entry.
Severity
