Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

Insufficient control flow management in AmdCpmOemSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to an escalation of privileges.

Insufficient control flow management in AmdCpmGpioInitSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to escalation of privileges.

A race condition in System Management Mode (SMM) code may allow an attacker using a compromised user space to leverage CVE-2018-8897 potentially resulting in privilege escalation.

Failure to verify the protocol in SMM may allow an attacker to control the protocol and modify SPI flash resulting in a potential arbitrary code execution.

A malicious or compromised UApp or ABL may be used by an attacker to issue a malformed system call to the Stage 2 Bootloader potentially leading to corrupt memory and code execution.

Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.

Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.

Improper parameters handling in the AMD Secure Processor (ASP) kernel may allow a privileged attacker to elevate their privileges potentially leading to loss of 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.

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.

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 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.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.

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.

Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.

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.

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.
