AMD released a new version of the chipset driver to fix critical security vulnerabilities
AMD recently released a new Ryzen chipset driver, version 3.08.17.735, which fixes the critical security vulnerability of the AMD platform security processor driver. However, AMD did not disclose the details of the security vulnerabilities that were specifically patched. It is speculated that this fix is likely to be related to several vulnerabilities currently known in AMD processors.
On the official AMD website, several vulnerabilities in the current Ryzen series processors are listed, two of which will affect all Ryzen series processors. One is the bulletin id “AMD-SB-1003” (Speculative Code Store Bypass and Floating-Point Value Injection). The other is AMD-SB-1010 (Transient Execution of Non-canonical Accesses). The AMD-SB-1003 is when the processor handles incorrect floating-point values, which may cause the Ryzen series processors to leak data when processing overwritten instructions. The AMD-SB-1010 is also related to data leakage. When Ryzen series processors perform non-standard loads and store data with only 48 bits or less of address bits, data leakage may occur.
Since AMD did not specify the details of this Ryzen chipset driver update, we are not sure if these issues have been fixed. Previously Intel was tossed due to Meltdown and Spectre flaws, AMD has also exposed many security vulnerabilities in the past two years, although most of them have little to do with ordinary users, for ordinary users, it is best to update the Ryzen chipset driver to the latest version.
