I _guess_ that capabilities are used to avoid SUID binaries when this is
secure.

Read the caveat here: https://w1.fi/cgit/hostap/plain/wpa_supplicant/README .
Basically, you'll need a special user/group for executing

In general, why is this necessary? What kind of attack (besides DoS) is
possible against wpa_supplicant?
