AMD has recently announced that certain models of its Ryzen CPUs are susceptible to vulnerabilities that could potentially be exploited by malicious individuals, resulting in unauthorized control over user devices or disruption of their functionality. Although the company has already addressed the issue and released a fix, immediate action is recommended for users to safeguard their systems and personal information.
The vulnerability primarily arises through the Serial Peripheral Interface (SPI) connection between the CPU and the motherboard, affecting select AMD CPUs listed in our best gaming CPU guide. Therefore, it is crucial for all AMD Ryzen CPU users to promptly download the latest BIOS update for their respective motherboards in order to mitigate the risks associated with this vulnerability.
To rectify the issue, AMD has utilized the AMD Generic Encapsulated Software Architecture (AGESA) and incorporated the necessary fixes into its BIOS/UEFI updates. While AMD has distributed the updated AGESA versions to address the vulnerabilities, some motherboard manufacturers have yet to make the user-downloadable BIOS update available.
While the AM5-based boards, as well as TRX50 and WRX90 motherboards, are confirmed to be secure against these vulnerabilities, older motherboards require further evaluation. Currently, there are no AM4 motherboards that offer a BIOS version with the latest AGESA 1.2.0.C, leaving Ryzen 4000G and 5000G APUs vulnerable regardless of the motherboard used.
In contrast, the more recent AGESA version 1.2.0.B has been adopted by many 500 series boards from reputable manufacturers including Asus, ASRock, Gigabyte, and MSI. However, a significant number of lower-tier 300 and 400 series boards are still operating on version 1.2.0.A, lacking the necessary updates.
To ensure optimal security, it is strongly recommended to check for the availability of a BIOS update tailored for your specific motherboard, regardless of the CPU and chipset combination you have in place. By visiting the respective motherboard manufacturer’s website and comparing the AGESA version of the latest update with those mentioned on AMD’s official website, users can gain insight into the compatibility of their system and implement the necessary measures.
It is worth mentioning that Intel CPUs are not exempt from vulnerabilities, and it is equally crucial for Intel CPU users to keep their motherboards updated to mitigate any potential threats. Regularly updating the BIOS is an essential step in maintaining the security and stability of your system, regardless of the brand or model of your CPU.
