|
Insufficient control flow management in AmdCpmOemSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to an escalation of privileges.
|
| 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. |
| Insufficient bounds checking in ASP (AMD Secure
Processor) may allow for an out of bounds read in SMI (System Management
Interface) mailbox checksum calculation triggering a data abort, resulting in a
potential denial of service.
|
| Time-of-check Time-of-use (TOCTOU) in the
BIOS2PSP command may allow an attacker with a malicious BIOS to create a race
condition causing the ASP bootloader to perform out-of-bounds SRAM reads upon
an S3 resume event potentially leading to a denial of service.
|
| Failure to validate the length fields of the ASP
(AMD Secure Processor) sensor fusion hub headers may allow an attacker with a
malicious Uapp or ABL to map the ASP sensor fusion hub region and overwrite
data structures leading to a potential loss of confidentiality and integrity.
|
| Insufficient bounds checking in ASP (AMD Secure
Processor) may allow for an out of bounds read in SMI (System Management
Interface) mailbox checksum calculation triggering a data abort, resulting in a
potential denial of service.
|
| Improper syscall input validation in AMD TEE
(Trusted Execution Environment) may allow an attacker with physical access and
control of a Uapp that runs under the bootloader to reveal the contents of the
ASP (AMD Secure Processor) bootloader accessible memory to a serial port,
resulting in a potential loss of integrity.
|
| A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity and availability. |
| Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.
|
| A stack buffer overflow vulnerability discovered in AsfSecureBootDxe in Insyde InsydeH2O with kernel 5.0 through 5.5 allows attackers to run arbitrary code execution during the DXE phase. |
|
An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially leading to arbitrary code execution.
|
|
A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality.
|
| 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. |
