AI-suggested
Mitigation should focus on enabling and properly configuring IOMMU in the motherboard firmware (BIOS/UEFI) settings to enforce DMA restrictions. Organizations should verify that IOMMU is active on all affected systems and apply any firmware updates or patches released by GIGABYTE promptly once available. Physical security controls must be strengthened to prevent unauthorized access to hardware, including locked server rooms, surveillance, and access logging. Use of hardware-based security modules or trusted platform modules (TPMs) can help detect unauthorized hardware changes. Network segmentation and monitoring for unusual device connections can provide additional layers of defense. For environments where physical access cannot be fully controlled, consider replacing affected hardware with models confirmed to have proper IOMMU enforcement. Regular security audits and penetration testing should include checks for DMA attack vectors. Finally, educate IT staff about the risks of DMA attacks and the importance of firmware configuration.
Description
Certain motherboard models developed by GIGABYTE has 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.
