AMD has released new chipset drivers for its popular range of Ryzen processors, which include the latest Ryzen 5000 Series and 3rd Gen Ryzen Threadripper CPUs. Versioned 3.08.17.735, the new driver includes critical security fixes that have been implemented into the AMD PSP Driver, alongside new device ID support and some bug fixes for the AMD MicroPEP Driver.

AMD didn’t really elaborate on what exact security issues were patched, but they presumably relate to the two Ryzen vulnerabilities listed on AMD’s security bulletin. One is a “Speculative code store bypass and floating-point value injection” vulnerability, which can cause Ryzen CPUs to leak data. The second vulnerability, “Transient Execution of Non-canonical Accesses,” also involves data leakage.

In most cases, the simple process of installing or upgrading the AMD Ryzen chipset drivers can be completed without issues. However, if there have been recent changes to your system hardware configuration or the currently installed chipset drivers are extremely outdated, then it is recommended to uninstall the existing chipset drivers before installing the new package. Performing the uninstall ensures a clean system and can help reduce issues or conflicts which may occur with the new installation.
