AMD updates AGESA 1.2.0.3e: Fixes TPM vulnerability and adds support for Ryzen 9000G

Recently, AMD has launched distribution of its new AGESA microcode version.Known as ComboAM5 1.2.0.3e, designed to renew security and support for AM5 platforms. This update has a key impact on both stability and system protection, especially against the growing importance of TPM 2.0 due to the requirements of Windows 11. Some models have already benefited from similar patches for months, but this iteration seeks to Cover a larger portion of computers and fix a recently discovered critical vulnerability.

Hardware security has become a top priority in the PC ecosystem, and firmware-based fTPM systems, integrated into most modern AMD CPUs, have received special attention. The recent discovery of an exploitable vulnerability in TPM 2.0 modules has put both users and manufacturers on alert, since could compromise the privacy and integrity of sensitive data stored by the operating system.

AGESA 1.2.0.3e: Critical vulnerability fix in fTPM

The core of this update lies in the correction of a security flaw in the fTPM, which was detected and reported by the Trusted Computing Group Vulnerability Response TeamThe issue, technically described as an out-of-bounds read in the TPM 2.0 module library, could be exploited by attackers to extract sensitive information or destabilize the component.

AMD has implemented this fix in the new version of AGESA, which is already being distributed in the BIOS of AM5 motherboards from manufacturers such as ASUS, MSI and ASRock. The distribution will be staggered, but updated BIOSes already exist, as in the ROG Crosshair X870E Hero. Additionally, other motherboards with the 600 and 800 series chipsets will also receive this update.

Support for new Ryzen 9000G and 9700F processors

Along with the improvement in security, AGESA 1.2.0.3e also adds support for new processor modelsAmong these, the family stands out. Ryzen 9000G, known as "Gorgon Point." These APUs, manufactured on a 4nm node and based on Zen 5 architectures, offer a monolithic design and are aimed at desktop systems.

The manufacturers confirm that, In addition to Ryzen 9000G, the Ryzen 9700F is added., a processor without integrated graphics that generates expectations in the mid- and high-end market. These models are designed to respond to both traditional tasks and artificial intelligence applications, thanks to the NPU XDNA 2 with a capacity of more than 50 AI TOPS, which is relevant for functions such as Microsoft Copilot+.

As for its specifications, the Ryzen 9000G will have a hybrid core design: one CCX with four standard Zen 5 cores and another with eight efficient Zen 5c cores. The integrated graphics will be based on architecture RDNA3.5 with 16 computing units, and PCI Express connectivity will be limited to a Gen 4 x8 link, suitable for its segment.

BIOS updates and affected platforms

The deployment of AGESA 1.2.0.3e not only benefits those who plan to install new processors, but also recommends to those who already use CPUs from Zen 3 to Zen 5Some models like the Athlon and Ryzen 3000 already received similar security patches since January, but other families like the Ryzen 5000 Vermeer, Ryzen 7000, and Ryzen 9000 have been updated more recently.

It is essential to keep the BIOS updated, since security in Windows 11 depends largely on the proper functioning of TPM 2.0. AMD considers this vulnerability to be of medium severity., which is why it is recommended check and update the system as much as possible before.

In addition, the update improves support for advanced memory configurations, allowing management of up to 256 GB in four 64 GB modulesThis is especially useful in professional or highly multitasking environments.

AMD's move with AGESA 1.2.0.3e reflects a focus on balancing security, compatibility, and readiness for future processor generations. Through collaboration with manufacturers and rapid implementation, AM5-based systems will be better prepared for current challenges and hardware developments.

This microcode update strengthens security against threats that affect the TPM, in addition to facilitating support for future generations of AMD hardware and enhancing stability in advanced configurations on modern computers.
