Potential weakness in AMD SPI protection features may allow malicious attackers to bypass kernel mode protections

CVE-2022-23829

Summary

A potential weakness in the SPI protection features of AMD systems enables a malicious actor with Ring0 (kernel mode) access to circumvent the built-in protections of the System Management Mode (SMM) ROM. This may lead to unauthorized access to critical system functions, potentially compromising the integrity of the entire system. Organizations utilizing affected AMD products should assess their security measures and enhance their defenses against potential exploitation.
