The CVE-2017-9417 aka "Broadpwn" vulnerability is said to affect the
firmware for various Broadcom BCM43xx wifi chips, some of which are
supported by the in-tree brcmfmac driver and firmware in linux-
firmware.git.
The bcmdhd driver for Android was patched to improve validation of
events from the firmware:
https://android.googlesource.com/kernel/msm.git/+/android-6.0.1_r0.92%5E!/
But the event handling code in
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fweh.c still seems to
lack most of those checks. Should it be patched?
I also haven't seen any related updates for BCM43xx firmware in linux-
firmware.git. Is any of this firmware vulnerable?
Ben.
