US EditionA New Malware Is Infecting Gigabyte Motherboards – and There Likely Won't Be a Fix Any Time Soon
GLOBAL, JUL 14 – Four high-severity flaws in Gigabyte UEFI firmware allow attackers to execute persistent bootkit malware on over 240 Intel-based motherboard models, exposing supply chain risks, researchers say.
- On April 15, 2025, security experts from Binarly informed Carnegie Mellon University's CERT/CC about four severe vulnerabilities affecting the UEFI firmware in over 240 models of Gigabyte motherboards.
- These flaws stem from American Megatrends code but were not properly integrated by Gigabyte, causing vulnerable firmware to reach consumers from 2017 to 2021.
- The vulnerabilities reside in System Management Mode, allowing attackers with admin access to bypass Secure Boot and install persistent bootkit malware that survives OS reinstalls.
- Gigabyte confirmed the issues on June 12, 2025, began releasing patches for some motherboards, but nearly half are end-of-life and will likely remain unpatched, leading to recommendations to contact Field Application Engineers or replace hardware.
- This situation leaves many users exposed to advanced persistent threats, implying that hardware replacement is the only practical mitigation for unsupported systems.
