Statement

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 on ppc64 and ppc64le platforms. This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.

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.
