ASUS Motherboards Uncontrolled Resource Consumption Vulnerability Allowing Unauthorized Direct Memory Access

A vulnerability allowing uncontrolled resource consumption has been identified in certain ASUS motherboards that use Intel B460, B560, B660, B760, H410, H510, H610, H470, Z590, Z690, Z790, W480, and W680 series chipsets. This vulnerability requires physical access to the internal expansion slots to install a specially crafted device along with a supporting software utility. Exploitation of this vulnerability could lead to excessive resource consumption, increasing the risk of unauthorized direct memory access (DMA).

Impact

Exploitation of this vulnerability could result in unauthorized direct memory access (DMA), allowing an attacker to bypass normal memory access controls and potentially read or modify sensitive information.

Remediation

Users are advised to refer to the 'Security Update for UEFI firmware' section on the ASUS Security Advisory for guidance on applying the necessary firmware update.
