This looks like a bug to me; STM32Cube_FW_F4 V1.17.0 contains CMSIS-DSP libraries for Cortex-M7 - I haven't yet tried using them, but I'm pretty sure the CPU in the F4-series is a Cortex-M4F. Is this not a bug?
STM32Cube F4 V1.17.0 has incorrect CMSIS GCC library
Thank you - I clearly didn't try searching hard enough.
The search here isn't always very effective, I was involved in the conversation but still had to strafe the search terms to pull it up.
