Comment 1 for bug 1783385

This was fixed in cosmic in https://launchpad.net/ubuntu/+source/intel-microcode/3.20180703.2ubuntu1 ; pacakge for trusty, xenial, and bionic are available for testing in the ubuntu-security-proposed ppa: https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/ . Please note that packages in this ppa are for testing only and have not been widely tested, and thus should not be used in production.

Thanks.
