Created kernel tracking bugs for this issue: Affects: fedora-all [bug 1545617]
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.
This was fixed for Fedora with the 4.14.8 stable updates.
