Improper Access Control in an on-chip debug interface could allow a privileged attacker to enable a debug interface and potentially compromise data confidentiality or integrity.

Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity.

Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution.

An out-of-bounds read in the ASP could allow a privileged attacker with access to a malicious bootloader to potentially read sensitive memory resulting in loss of confidentiality.
