Motherboard manufacturers are rolling out new BIOS updates based on AMD’s AGESA 1.2.0.3e firmware to address a security vulnerability in the Trusted Platform Module (TPM).

Riot Games' popular shooter game Valorant, for example, was spotted as requiring TPM 2.0. It isn't clear, however, if that requirement applies to both Windows 11 or even Windows 10.

Microsoft updated its guidance to say that the Windows 11 TPM requirement will be for a TPM 2.0 security chip, suggesting that Windows 10 PCs made prior to 2019 may not be Windows 11 compatible.

TPM 2.0 is a “non-negotiable standard for the future of Windows,” said Steven Hosking, Microsoft senior product manager, in a Wednesday blog post.

A large number of AMD CPUs, including Ryzen 7000, 8000, and 9000 processors, are vulnerable to a security flaw that could allow hackers to retrieve sensitive information within the TPM.

The Trusted Platform Module (TPM) 2.0 specification is affected by two buffer overflow vulnerabilities that could allow attackers to access or overwrite sensitive data, such as cryptographic keys.

Microsoft has begun enforcing its TPM 2.0 requirement for Windows 11 builds on virtual machines.
