New UEFI Flaw Enables Early-Boot DMA Attacks on ASRock, ASUS, GIGABYTE, MSI Motherboards Certain motherboard models from vendors like ASUSTeK Computer, and are affected by a security vulnerability that leaves them susceptible to early-boot direct memory access ( ) attacks across architectures implement Unified Extensible Firmware Interface input–output management unit IOMMU ). designed enforce foundation prevent peripherals performing unauthorized accesses, effectively ensuring DMA-capable devices can manipulate or inspect system before the operating is loaded. The vulnerability, discovered Nick Peterson Mohamed Al-Sharifi of Riot Games in certain implementations, has do with discrepancy protection status. While firmware indicates active, it fails configure enable during critical boot phase. "This gap allows malicious Peripheral Component Interconnect Ex... https://thehackernews.com/2025/12/new-uefi-flaw-enables-early-boot-dma.html
