High [CVE-2026-68325] Bound the early ACPI HID map
CVE-2026-68325Source published Source updated
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. This vulnerability occurs because the parser does not properly bound the `early_acpihid_map` array, allowing it to append more entries than its fixed four-element capacity. A local attacker could exploit this out-of-bounds write to cause a denial of service or potentially execute arbitrary code. Red Hat severity: Moderate — CVSS 7…
