Statement:

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, as the related AIO vector code is not present in this product.

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 6, 7 and MRG-2. Future Linux kernel updates for the respective releases might address this issue.
