Buffer Validation Flaw in AMD BIOS Enables Potential Code Execution

CVE-2021-26316

Summary

A vulnerability exists in the BIOS of AMD products due to improper validation of the communication buffer and service. This oversight could allow attackers to exploit the buffer, potentially leading to arbitrary code execution in the System Management Mode (SMM). This type of vulnerability poses significant risks as it operates at a high privilege level within the BIOS, enabling unauthorized access and control over the system.
