Yesterday released a new Ryzen chipset driver update, Version 3.08.17.735, To patch the “critical security hole” in the platform security processor driver. AMD has not disclosed the exact details of the patched security vulnerabilities, but we speculate that they may be related to several current AMD vulnerabilities.
Currently, AMD has two vulnerabilities that affect all listed Ryzen-based CPUs AMD’s website. One of them includes Speculative code storage bypass and floating point value injection Vulnerability, when the CPU processes incorrect floating-point numbers, the vulnerability may cause the Ryzen CPU to leak data when processing overwrite instructions.The second vulnerability is also related to data breaches, called Instantaneous execution of non-normative access. This vulnerability could allow data leakage when the CPU performs non-canonical loads and only uses 48 address bits or less to store these numbers.
We are not entirely sure that these are bugs that have been fixed in AMD’s new PSP driver. Either way, it is best to update your Ryzen chipset driver to this new version to ensure that you are not exposed to unknown vulnerabilities. Especially when AMD classifies these security vulnerabilities as “critical.”
