Sub-Byte Binary Underflow in WiFi Devices

Warning: Test With Extreme Care

Sending WiFi beacons where the SSID is set to some non-byte number of bits and a poorly matching SSID length breaks many random WiFi devices in range.

Some devices freeze, some reboot, some break, some brick.
Results are superfically non-deterministic and further study is required.

In theory, it could be leveraged into other forms of binary exploitation.

List of devices vulnerable is unknown and likely very large.
