New UEFI Flaw Enables Early-Boot DMA Attacks on ASRock, ASUS, GIGABYTE, MSI Motherboards

Certain motherboard models from vendors like ASRock, ASUSTeK Computer, GIGABYTE, and MSI are affected by a security vulnerability that leaves them susceptible to early-boot direct memory access (DMA) attacks across architectures that implement a Unified Extensible Firmware Interface (UEFI) and input–output memory management unit (IOMMU).
UEFI and IOMMU are designed to enforce a security
