Vulnerabilities in Big-IP 10.2.4, 9.4.8, and 9.4.3

Citing from K4602: Overview of the F5 security vulnerability response policy:

"When a vulnerability is publicly disclosed, F5 is committed to evaluating the software versions that have not yet reached End of Technical Support (EoTS), as indicated in the software support policy articles for each product. For more information, refer to F5 software products currently supported with active development in K8986: F5 software lifecycle policy.

When critical vulnerabilities are discovered, F5 implements, tests, and releases security hotfixes for the supported software versions, where technically feasible. For additional information regarding the F5 critical issue hotfix policy, refer to K4918: Overview of the F5 critical issue hotfix policy."

As stated in K5903: BIG-IP software support policy all the software you are running is EoTS.

In other words: F5 will not check whether or not the software you are running is vulnerable.

I recommend you start from here:
