Beware, This Network Name Can Disable Wi-Fi Access on iPhone

Even so, there are assumptions that can explain why the WiFi SSID name can have an impact on the iPhone. It is suspected that the iOS system reads the ‘%’ symbol at the beginning of the SSID name as a programming command.

9to5mac write, the formula syntax ‘%[karakter]’ is usually used in programming languages ​​to format variables to output string.

While the ‘%n’ at the end of the network name serves to store the number of characters written in the format string to a variable that is passed to the format function string.

Thus, the Wi-Fi subsystem that detects it will forward the name of the Wi-Fi network that is not safe to perform format string in the system.

As a result, memory writes and buffer overflow uncertain. Then, this will cause memory corruption and the iOS watchdog system will kill the process, effectively disabling Wi-Fi for the user.

Until Apple fixes bug This is deep update In the future OS, users are asked to be careful when connecting Wi-Fi networks, especially those that have the ‘%’ symbol in them.
