17.0.0. It is, therefore, affected by a vulnerability as referenced in the K52340447 advisory.

  - On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior
    to 14.1.4.6, and 13.1.x versions prior to 13.1.5, on platforms with an ePVA and the pva.fwdaccel BigDB
    variable enabled, undisclosed requests to a virtual server with a FastL4 profile that has ePVA
    acceleration enabled can cause the Traffic Management Microkernel (TMM) process to terminate. Note:
    Software versions which have reached End of Technical Support (EoTS) are not evaluated (CVE-2022-28705)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
