Impact

A use‑after‑free flaw in the AMD Ryzen Master Utility Driver permits a local attacker to read kernel memory, which could result in loss of availability.

Affected Systems

The AMD Ryzen Master Utility Driver and the AMD Ryzen Master Monitoring SDK are affected. No specific version information has been released in the advisory.

Risk and Exploitability

The CVSS score of 5.6 indicates moderate severity, while an EPSS score of less than 1% shows a very low probability of exploitation. The vulnerability can only be triggered by a local attacker with access to the driver and it is not listed in the CISA KEV catalog. Consequently, the likelihood of successful exploitation in the wild remains low, though the potential impact on system availability is real.
