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
