Hi,
If understand correctly CVE-2017-9417 (aka. the "broadpwn" exploit) is
addressed by firmware updates in new drivers recently released by some
major vendors.
Is there a systematic way to extract the new firmware to help secure
Linux systems with BCM43xxx devices?
In my specific case I have a MacBook Pro 12.1 with a BCM43602 running
Linux and the brcmfmac driver, but have an old partition with OS X. I
was hoping it might be possible to extract the firmware from the
latest OS X updates? Or, maybe there is a way to get the latest
release of Linux drivers from Broadcom and extract from there? (I had
a bit of trouble figuring out if there is a specific Broadcom page for
the latest version of their restrictively licensed drivers).
I appreciate this could be a contentious issue and apologise in
advance if this is the wrong forum for this discussion.
Kind regards,
Jacob
