-
A problem was fixed for a security vulnerability for the Self-Boot Engine (SBE). The SBE can be compromised from the service processor to allow injection of malicious code. An attacker that gains root access to the service processor could compromise the integrity of the host firmware and bypass the host firmware signature verification process. This compromised state can not be detected through TPM attestation. This is Common Vulnerabilities and Exposures issue number CVE-2021-20487.
