Google has developed a fix for a critical remote code execution vulnerability in Broadcom Wi-Fi firmware. There is a huge amount of information (and possibly this) available around it, but as an end user my primary concern is this: how do I avoid being hacked while waiting for a patch?
According to the detailed report this specific problem can be triggered by specifically constructed Wi-Fi packets. From my understanding this kind of attack should possible for an unauthorized attacker and it does not matter if the victim is associated with a Wi-Fi network or not. This means that the only workaround to protect a vulnerable device is too completely disable Wi-Fi.
