AMD has published updated chipset drivers for its popular Ryzen processors, including the newest Ryzen 5000 Series and 3rd Generation Ryzen Threadripper processors. The updated driver, which is versioned, contains important security improvements for the AMD PSP Driver, as well as new device ID support and bug fixes for the AMD MicroPEP Driver.

AMD didn’t go into detail about the security flaws that were fixed, although they’re most likely related to the two Ryzen vulnerabilities mentioned in AMD’s security advisory. One is a vulnerability known as “Speculative code store bypass and floating-point value injection,” which allows Ryzen CPUs to leak data. Data leaking is likewise a concern with the second vulnerability, “Transient Execution of Non-canonical Accesses.”

The easy procedure of installing or updating the AMD Ryzen chipset drivers may usually be done without problems in most instances. However, if your system hardware configuration has recently changed or the presently installed chipset drivers are very old, uninstalling the previous chipset drivers before installing the new package is advised. The uninstall guarantees a clean system and may assist in reducing problems or conflicts that may arise during the fresh installation.
