AMD Security Vulnerability: Secure Encrypted Virtualization Invalid ECC Curve Points (SEV ECC) in Linux Operating System vulnerability
more information:
Through the ongoing collaboration with industry researchers AMD became aware that, if using the user-selectable AMD secure encryption feature on a virtual machine running the Linux operating system, an encryption key could be compromised by manipulating the encryption technology’s behavior.
AMD is releasing firmware-based cryptography updates to mitigate specified vulnerabilities and these updates will be incorporated into Supermicro BIOS.
Supermicro is working closely with AMD to remediate this issue in the H11 series motherboards that support AMD Processors.
