AMD SMM Vulnerabilities
AMD ID: AMD-SB-7027
Potential Impact: Arbitrary Code Execution
Severity: High
Summary
Quarkslab reported vulnerabilities that could allow attackers to execute code within SMM (System Management Mode).
CVE-2024-21925 is the result of a lack of sufficient input buffer(s) validation within the AmdPspP2CmboxV2 UEFI module. CVE-2024-0179 is an SMM (System Management Mode) Callout vulnerability within the AmdCpmDisplayFeatureSMM UEFI module. Both can allow ring-0 attackers to escalate their privileges, potentially resulting in arbitrary code execution. AMD has begun releasing firmware mitigations to fix these vulnerabilities.
