CVE-2017-9417 firmware fix with b43-fwcutter?

Hello,

I would join Drew in asking a question about CVE-2017-9417/Broadpwn.
My main concern is if this flaw in a firmware above can affect
laptop/desktop/server Linux systems?

So far I see two contradicting answers: "he could reproduce the crash
with the standard Linux firmware [on a mobile phone]" and "I do not
think that Broadpwm is a problem". Can someone please clarify?

I'm also trying to reach Broadcom guys via different channels with this
question, no reply for now.
