CVE-2026-68325
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
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.
