Kr00k Vulnerability Information
The Kr00k vulnerability potentially affects all WiFi-capable devices that use WiFi chips made by Broadcom or Cypress. This includes several Zebra mobile computers and tablets.
The vulnerability exploits a temporary disconnect of the WiFi signal (state transition/disassociation). A malicious actor could force devices into a prolonged disassociated state, receive WiFi packets meant for the attacked device, and then use the Kr00k bug to decrypt WiFi traffic.
Only the following products are affected. Other Zebra mobile devices, handheld devices, barcode scanners and printers are not impacted.
