Motherboards produced by major manufacturers including Gigabyte, MSI, ASUS, and ASRock are reportedly vulnerable to a new attack exploiting a UEFI flaw. This vulnerability allows direct memory access attacks on many popular devices. The issue was highlighted in a TechRadar report published on December 22, 2025.
A recent security alert has raised concerns over vulnerabilities in motherboards from leading brands such as Gigabyte, MSI, ASUS, and ASRock. According to TechRadar, these components are at risk from a novel attack targeting flaws in the Unified Extensible Firmware Interface (UEFI). UEFI serves as the firmware that initializes hardware during a device's boot process, making any weaknesses particularly dangerous.
The report details that the flaw enables direct memory access (DMA) attacks, which could allow unauthorized entities to bypass operating system protections and access sensitive data or inject malicious code. Many popular consumer and professional devices incorporating these motherboards are affected, potentially exposing users to risks like data theft or system compromise.
Published on December 22, 2025, the TechRadar article emphasizes the widespread nature of the vulnerability, urging affected users to monitor updates from manufacturers. While specific mitigation steps were not outlined in the available details, the exposure underscores ongoing challenges in securing firmware against evolving cyber threats. No immediate exploits have been confirmed, but the potential for abuse remains a key concern in the cybersecurity landscape.
