Intel Processor L1TF vulnerabilities: CVE-2018-3615, CVE-2018-3620, CVE-2018-3646


Hi, How do we go about this fix for the servers. We are using Win2003 standard, Win2003 R2 and Win2008 standard 64 bit. Is there a utility tools to run and check that are in the vulnerability ?

Patching the wrong firmware will be disaster.

Best regards,

Hi Bombshell,



You will need to check with the manufacturer of your systems to obtain a BIOS update that includes the microcode versions that mitigate this issue. If your servers are from Intel (vs. Dell, HP etc.) then you can find information here:



You will also need to check with Microsoft to obtain the security patches for your servers.



There is not a super easy tool that can tell you if a system is vulnerable, but this page from Microsoft has details on using PowerShell to determine if a system is vulnerable: (this page also has information on mitigating side-channel vulnerabilities disclosed earlier this year)
