      Hello Jukka,

      Nice and informative blog. Can you please answer below questions?


      What is the impact on SAP performance when updating BIOS on VM?

      Do we need to change the existing CPU types if there is any impact?

      Is it tested by SAP for linux environment?


      Thanks in advance.

      Hi Ateek,

      There is no general answer for all SAP products, every product has different aspect to the vulnerability depending on how data is processed.

      This blog covers product called SAP Contact Center and I have no answers for other products. I recommend you to raise an customer incident for more details.
