This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 6 and 7 on ppc64 and ppc64le platforms. Future Linux kernel updates for the respective releases might address this issue.
Only ppc64 and ppc64le hardware platforms are vulnerable. The Linux kernel packages for other platforms which Red Hat ships (i386, x86_64, s390x) are not vulnerable to this security flaw.
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux MRG-2 as this product is shipped for x86_64 hardware platform only.
