CVSS v3.1 |
| 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 checks in SEV may lead to a malicious hypervisor disclosing the launch secret potentially resulting in compromise of VM confidentiality.
|
| 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.
|
| Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service.
|
| Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service.
|
| Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service.
|
| Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality.
|
| Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service.
|
| Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service.
|
| TOCTOU in the ASP may allow a physical attacker to write beyond the buffer bounds, potentially leading to a loss of integrity or denial of service.
|
| A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow
an attacker with ring0 privileges and access to the
BIOS menu or UEFI shell to modify the communications buffer potentially
resulting in arbitrary code execution. |
| 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. |
| An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. |
| IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. |
| An attacker with a compromised ASP could
possibly send malformed commands to an ASP on another CPU, resulting in an out
of bounds write, potentially leading to a loss a loss of integrity.
|
| Improper access control settings in ASP
Bootloader may allow an attacker to corrupt the return address causing a
stack-based buffer overrun potentially leading to arbitrary code execution.
|
| Improper input validation in ABL may enable an
attacker with physical access, to perform arbitrary memory overwrites,
potentially leading to a loss of integrity and code execution.
|
| Insufficient syscall input validation in the ASP
Bootloader may allow a privileged attacker to execute arbitrary DMA copies,
which can lead to code execution.
|
| Improper validation of DRAM addresses in SMU may
allow an attacker to overwrite sensitive memory locations within the ASP
potentially resulting in a denial of service.
