...merely for engine accessories ventilation...
Equivalent inlets can be found under nacelles on DC8-70s and B-737s...

I believe the exhaust ports you're referring to are for the engine inlet anti-ice system. You put hot air in, its got to go somewhere.

Thanks for your info.
Perhaps the accessories receiving ventilation, as mentioned by B747skipper, are indeed the pipes used for the engine inlet anti-ice system as mentioned by Airgxs.
I believe you can see the hot anti-ice bleed air pipes around the front of this engine.

Regarding my question about whether or not CFM-56 engines were also used on civilian airliners, well, I believe I found the answer myself. Some Airbus A320s use CFM-56 engines, and some of these engines have similar exhausts/vents in their cowlings, and some of them don't.

The CFM-56 is used on Boeing 737-300s, 400s, 500s, 600s, 700s 800s and 900s, A319s, A320s, A321s and A340s, and the DC-8-70 series of re-engined DC-8s, to name a few!

The vents are for the nacelle anti-ice exhaust.
