> Broadpwn is a fully remote attack against Broadcom’s BCM43xx family of WiFi chipsets, which allows for code execution on the main application processor in both Android and iOS. This implies they have code execution on the application processor just from broadpwn (and not additional safari/ios exploits). Hijacking internet traffic is indeed serious but tech blog sites are already picking up on this and blowing it up.

Probably because a device on the system itself has tremendous privileges; aside from interacting with non-hardened kernel code (drivers generally trust the device but to be malicious), they generally have DMA access, in PCI can impersonate the CPU when speaking to other devices, and can generally cause all kinds of havoc.
