CVE-2026-68325 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rhcos package and not the rhcos package as distributed by RHEL.
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.
