Comment 6 Eric Christensen 2018-02-15 13:28:19 EST 
Statement:

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, and 7, its real-time kernel, Red Hat Enterprise MRG 2, Red Hat Enterprise Linux 7 for ARM 64, and Red Hat Enterprise Linux 7 for Power 9 LE, as the code with the flaw is not enabled and is not built in the products listed.
