Regarding this link -> https://support.f5.com/csp/article/K56480726
(Updated Date: Apr 22, 2019)
I guess this document means that they are not affected to this vulnerability because of they normally develop a custom kernel with fixes written by their own, and the root of the vulnerability refers to code not implemented in their products.
However, the best way to know details about that is to open a support case. Normally they are reluctant to give details about the bugs, but in this case it's the best way to obtain responses.
