AMD AMD EPYC™ 9V64H Processor vulnerabilities

Incorrect default permissions in the installation directory for the AMD chipset driver could allow an attacker to achieve privilege escalation resulting in arbitrary code execution.

Incorrect default permissions in the installation directory for the AMD general-purpose input/output controller (GPIO) could allow an attacker to achieve privilege escalation resulting in arbitrary code execution.

Incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation potentially resulting in arbitrary code execution.

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