as per the webpage below processors are affected:
Please let us know if the CPUs we are using are not on the above affected CPU list can we just ignore the issue INTEL-SA-00086? For your reference we have a Dell OEM server with Intel Pentium G4500 3.5GHz, 3M cache, 2C/2T, no
turbo (65W) . Would be helpful if this CPU has influence from INTEL-SA-00086 vulnerabilities.
Thank you for joining the Intel® Community. I can sure help with this matter.
As you can confirm in our documentation, your processor is not listed as an affected product. However, if you are still concern I recommend to contact Dell directly in order to check if from their end there is more information about the motherboard you are using.
