Vulnerability AssessmentAI

Exploitation Exploitation requires: (1) local access to the target Windows system; (2) high-privilege credentials (administrator or equivalent, per PR:H); (3) AMD Ryzen Master or the Monitoring SDK installed and the associated kernel driver loaded; and (4) a specific attack target condition (AT:P) - the exact driver state or race window required is not detailed in available data. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:H) firmly situates this as a local, high-privilege denial-of-service issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update AMD Ryzen Master to version 3.1.1.5502 or later and AMD Ryzen Master Monitoring SDK to version 3.1.1.5478 or later, as specified in AMD security bulletin AMD-SB-9020 (https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-9020.html). … Detailed patch versions, workarounds, and compensating controls in full report.
