AI-suggested
- Enforce strict physical security controls to prevent unauthorized access to hardware, including locked server rooms and restricted access to workstations.
- Disable or physically block unused PCIe slots to reduce the attack surface for DMA-capable devices.
- Employ hardware-based security features such as Intel VT-d or AMD-Vi where applicable, ensuring IOMMU is properly enabled and configured in BIOS/firmware settings.
- Monitor system logs and hardware inventory for unauthorized or unexpected PCIe devices.
- Use endpoint detection and response (EDR) solutions capable of detecting anomalous low-level memory access patterns.
- Coordinate with ASRock for firmware updates or patches addressing this vulnerability and apply them promptly once available.
- Consider deploying hardware with verified IOMMU configurations or alternative chipsets if immediate mitigation is not feasible.
- Educate IT and security staff about the risks of DMA attacks and the importance of physical security in mitigating such threats.
Description
Certain motherboard models developed by ASRock and its subsidiaries, ASRockRack and ASRockInd.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.
