CVSS v3.1 |
| Insufficient input validation in
CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting
an arbitrary bit in an attacker-controlled pointer potentially leading to
arbitrary code execution in SMM.
|
| TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service. |
| Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. |
|
When SMT is enabled, certain AMD processors may speculatively execute instructions using a target
from the sibling thread after an SMT mode switch potentially resulting in information disclosure.
|
| Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure. |
| A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure. |
| Failure to validate the AMD SMM communication buffer
may allow an attacker to corrupt the SMRAM potentially leading to arbitrary
code execution. |
| Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information. |
| Insufficient input validation in the ASP (AMD
Secure Processor) bootloader may allow an attacker with a compromised Uapp or
ABL to coerce the bootloader into exposing sensitive information to the SMU
(System Management Unit) resulting in a potential loss of confidentiality and
integrity.
|
| LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. |
| Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) may allow an authenticated attacker with privileges to generate a valid signed TA and potentially poison the contents of the process memory with attacker controlled data resulting in a loss of confidentiality. |
| Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write potentially allowing an attacker with privileges to gain code execution of the OS/kernel by loading a malicious TA. |
| A malicious or compromised UApp or ABL may coerce the bootloader into corrupting arbitrary memory potentially leading to loss of integrity of data. |
| A malformed SMI (System Management Interface) command may allow an attacker to establish a corrupted SMI Trigger Info data structure, potentially leading to out-of-bounds memory reads and writes when triggering an SMI resulting in a potential loss of resources. |
| A malicious or compromised UApp or ABL may be used by an attacker to send a malformed system call to the bootloader, resulting in out-of-bounds memory accesses. |
| An attacker, who gained elevated privileges via some other vulnerability, may be able to read data from Boot ROM resulting in a loss of system integrity. |
| A malicious or compromised UApp or ABL may be used by an attacker to issue a malformed system call which results in mapping sensitive System Management Network (SMN) registers leading to a loss of integrity and availability. |
| A malicious or compromised User Application (UApp) or AGESA Boot Loader (ABL) could be used by an attacker to exfiltrate arbitrary memory from the ASP stage 2 bootloader potentially leading to information disclosure. |
| Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. |
| A timing and power-based side channel attack leveraging the x86 PREFETCH instructions on some AMD CPUs could potentially result in leaked kernel address space information. |
