UEFI Vulnerability Allows DMA Attacks on Certain Motherboards

Certain motherboard models from ASRock, ASUSTeK Computer, GIGABYTE, and MSI have a security vulnerability that exposes them to early-boot direct memory access (DMA) attacks on systems utilizing Unified Extensible Firmware Interface (UEFI) and input–output memory management unit (IOMMU). This vulnerability compromises the intended security measures of UEFI and IOMMU, which are meant to safeguard against such threats. Users of affected motherboards should take precautions to mitigate risks. Manufacturers are expected to release patches to address these vulnerabilities.
