CVE-2025-14302

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.

Summary		(es) Ciertos modelos de placas base desarrollados por GIGABYTE tienen una vulnerabilidad de fallo del mecanismo de protección. Debido a que IOMMU no se habilitó correctamente, atacantes físicos no autenticados pueden usar un dispositivo PCIe con capacidad DMA para leer y escribir memoria física arbitraria antes de que el kernel del sistema operativo y sus características de seguridad se carguen.
