AMD Ryzen™ Master Security Bulletin
Bulletin ID: AMD-SB-7004
Potential Impact: Varies by CVE, see descriptions below
Severity: Varies by CVE, see descriptions below
Summary
AMD Ryzen™ Master is a software tool that provides users access to advanced settings, such as clock and voltage settings, to control system performance in real-time.
An external researcher reported two potential vulnerabilities in AMD Ryzen™ Master caused by insufficient input validation in the IOCTL (Input Output Control) buffer. These vulnerabilities may allow an attacker with administrative privileges to potentially cause a Windows crash, resulting in loss of availability.
Alternatively, an attacker with administrative privileges may perform memory reads/writes potentially leading to a loss of confidentiality or arbitrary kernel execution.
