The problem is not limited to Apple computers, and appears to affect
drivers written by a wide range WiFi chipset makers. The Apple Macbook
is known to use an Atheros WiFi chipset, but numerous other chipsets
are also affected. Windows and Linux systems are at risk as well, as
the vulnerability affects device drivers that are provided by chipset
manufacturers. Systems running OpenBSD are unlikely to be affected
based on that open-source group's refusal to use "binary blobs" in
their device drivers, and their subsequent reverse engineering of
numerous WiFi chipsets to provide open-source alternatives to
manufacturer's device drivers.
