CVE-2021-26408

Insufficient validation of elliptic curve points in SEV-legacy firmware may compromise SEV-legacy guest migration potentially resulting in loss of guest's integrity or confidentiality.

CVE-2021-26398

Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.

CVE-2020-12988

A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted.

CVE-2021-26335

Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution.

CVE-2021-46774

Insufficient DRAM address validation in SystemManagement Unit (SMU) may allow an attacker to read/write from/to an invalidDRAM address, potentially resulting in denial-of-service.

CVE-2021-26356

A TOCTOU in ASP bootloader may allow an attackerto tamper with the SPI ROM following data read to memory potentially resultingin S3 data corruption and information disclosure.

CVE-2020-12951

Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations.

CVE-2021-26331

AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution.

CVE-2023-20578

A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allowan attacker with ring0 privileges and access to theBIOS menu or UEFI shell to modify the communications buffer potentiallyresulting in arbitrary code execution.
