CyberRota Analysis
AI-GeneratedA vulnerability exists in the Linux kernel's handling of the early ACPI HID map, where the ivrs_acpihid command-line parser can append more entries than the fixed four-element array allows, potentially leading to memory corruption. This flaw could be exploited to cause system instability or crashes. Linux system administrators and developers should prioritize this issue to ensure the integrity and reliability of their systems.
Original NVD 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.
