CVSS v3.1 |
| Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity. |
| Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution. |
| 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.
|
| Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.
|
| Insufficient fencing and checks in System Management Unit (SMU) may result in access to invalid message port registers that could result in a potential denial-of-service.
|
| Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests.
|
| Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure.
|
| Improper input validation and bounds checking in SEV firmware may leak scratch buffer bytes leading to potential information disclosure.
|
| Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability.
|
| An out of bounds memory write when processing the AMD
PSP1 Configuration Block (APCB) could allow an attacker with access the ability
to modify the BIOS image, and the ability to sign the resulting image, to
potentially modify the APCB block resulting in arbitrary code execution. |
| IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. |
| Insufficient address validation, may allow an
attacker with a compromised ABL and UApp to corrupt sensitive memory locations
potentially resulting in a loss of integrity or availability.
|
| Insufficient input validation of mailbox data in the
SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially
leading to a loss of integrity and privilege escalation.
|
| A compromised or malicious ABL or UApp could
send a SHA256 system call to the bootloader, which may result in exposure of
ASP memory to userspace, potentially leading to information disclosure.
|
| A TOCTOU in ASP bootloader may allow an attacker
to tamper with the SPI ROM following data read to memory potentially resulting
in S3 data corruption and information disclosure.
|
| Insufficient bounds checking in ASP may allow an
attacker to issue a system call from a compromised ABL which may cause
arbitrary memory values to be initialized to zero, potentially leading to a
loss of integrity.
|
| Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service. |
| Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service. |
| Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service. |
| Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service. |
