CVE-2018-11091 JCC SKX102 Erratum 

Updated microcode includes mitigations for CPU issues, but may also
cause a performance regression due to the JCC erratum mitigation.
Please visit http://www.intel.com/benchmarks for further information.

Please visit http://www.intel.com/security for detailed information on
these advisories as well as a list of CPUs that are affected.

Operating a CPU without the latest microcode may result in erratic or
unpredictable behavior, including system crashes and lock ups. Certain
issues listed in this advisory may result in the leakage of privileged
system information to unprivileged users. Please refer to the security
advisories listed above for detailed information.");
