CVE-2018-3665 how to fix on windows

Hi,

Recently I saw a CVE-2018-3665 details. I couldn't understand the solution to fix it.

We have a windows 2008, R2 server running on Dell R710 with Intel(R) Xeon(R) CPU E5520 @ 2.27GHz processor. According to this CVE, looks like its affected. Please suggest on how can I fix it? Will the security updates will take care of that?

Hello redhat.shre,

 

 

Thanks for joining the community.

 

Doesn't seem to be a processor related issue but OS related instead.

This is what I was able to find for CVE-2018-3665:

https://access.redhat.com/security/cve/cve-2018-3665 https://access.redhat.com/security/cve/cve-2018-3665

Mitigation

RHEL-7 will automatically default to (safe) "eager" floating point register restore on Sandy Bridge and newer Intel processors. AMD processors are not affected. You can mitigate this issue on older processors by booting the kernel with the 'eagerfpu=on' parameter to enable eager FPU restore mode. In this mode FPU state is saved and restored for every task/context switch regardless of whether the current process invokes FPU instructions or not. The parameter does not affect performance negatively, and can be applied with no adverse effects to processors that are not affected.

For clarification or corrections please contact Red Hat Product Security.

Regards,
