    Unfortunately not true. Redhat have a page https://access.redhat.com/articles/3553061 that says that RHEL6 and 7 and even 5 (which is quite dead) are all affected by this bug.

    Suse enterprise server is on 4.12. Debian Stretch and derivatives are 4.9.

    In kernel 4.17.11

    For those compiling their own kernels, these changes seem to have been incorporated in kernel 4.17.11 and above.
