Summary

Certain GIGABYTE motherboard models have a protection mechanism failure vulnerability. Because IOMMU was not properly enabled, unauthenticated physical attackers can use a DMA-capable PCIe device to read and write arbitrary physical memory before the OS kernel and its security features are loaded.

Risk Assessment

The risk includes the possibility of full system compromise before OS security features are loaded, potentially leading to system takeover and data theft.

Recommendation

It is recommended to enable IOMMU in BIOS/UEFI and install the latest firmware provided by the motherboard manufacturer.
