Ryzen 7 6800Hs Firmware Security Vulnerabilities - 2023
Certain size values in firmware binary headerscould trigger out of bounds reads during signature validation, leading todenial of service or potentially limited leakage of information aboutout-of-bounds memory contents.

Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of availability and integrity.
6.1CVSS
6.6AI Score
0.0004EPSS
Failure to validate the AMD SMM communication buffermay allow an attacker to corrupt the SMRAM potentially leading to arbitrarycode execution.
9.8CVSS
8.5AI Score
0.004EPSS
Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.
4.7CVSS
6.6AI Score
0.001EPSS
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.
8.1CVSS
6.8AI Score
0.001EPSS
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.
6.8CVSS
6.7AI Score
0.001EPSS
Improper input validation in the SMM Supervisor may allow an attacker with a compromised SMI handler to gain Ring0 access potentially leading to arbitrary code execution.
