CVE-2021-26312

Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity.

CVE-2020-12954

A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification.

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-2020-12944

Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution.

CVE-2020-12951

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

CVE-2021-26329

AMD System Management Unit (SMU) may experience an integer overflow when an invalid length is provided which may result in a potential loss of resources.

CVE-2021-26320

Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP

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-2021-26322

Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.

CVE-2021-26330

AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.

CVE-2021-26321

Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP.
