The vulnerability that is being exploited exists in a Broadcom Wi-Fi HardMAC system-on-a-chip that is present in many mobile devices.
These chips can handle many Wi-Fi-related processes without resorting to the host operating system.
Beniamini released the details of the vulnerability on 12 September. He had sent details of the vulnerability to Apple on 12 June and gave the company 90 days which has become some kind of a standard for responsible disclosure.
However, the code he provided was designed to be used only on the iPhone 7.
Beniamini said he had tested the exploit against the firmware on iOS 10.2 (14C92) and found it to work.
"...but (it) should work on all versions of iOS up to 10.3.3 (included). However, some symbols might need to be adjusted for different versions of iOS, see 'exploit/symbols.py' for more information," he said.
Apple patched the vulnerability in iOS 11 which was released last week.
