Board partners are now rolling out freshly baked BIOS updates based on AMD's AGESA 1.2.0.3e firmware. The updates are designed to patch a security flaw that could allow hackers to read sensitive data stored within the TPM (Trusted Platform Module), via VideoCardz. At least for some manufacturers, this BIOS update is a one-way street; you cannot roll back to an older release once you install it.
Hackers can exploit this security flaw by triggering an out-of-bounds read beyond the TPM2.0 routine. By doing so, these unauthorized users can gain access to sensitive data or disrupt the TPM's functionality as a whole. This stems from a bug (CVE-2025-2884), ranked 6.6 (Medium) on the CVSS scale, in TPM2.0's Module Library, which refers to standardized code that TPM 2.0 chips use for various functions.
