Description Rohit Keshri 2023-07-19 17:42:15 UTC

Insufficient validation in the IOCTL (Input Output Control) input buffer in AMD RyzenTM Master may permit a privileged attacker to perform memory reads/writes potentially leading to a loss of confidentiality or arbitrary kernel execution.

AMD RyzenTM Master is a software tool that provides the users access to advanced settings, such as clock and

voltage settings, to control system performance in real-time.
