Apple iOS has been affected by a bug that can disable your iPhone from getting connected to a wifi network. A security researcher Carl Shou has discovered the bug that breaks Wifi on iOS devices.
Carl Shou tried to connect his personal wifi with SSID “%p%s%s%s%s%n” and his iPhone completely lost the Wifi connectivity. He tried to connect to other hotspots but failed and got the same issue. Even others who tested out the bug reported the same issue.
Apple Discovered Bug in iOS 14.6 that can Break Wifi Connectivity
The cause of this bug isn’t clear, but there are reports that it might be a string formatting flaw. iOS might confuse the % entries with variables and commands. The researcher said that he regularly uses such names to mess with poor devices. And this bug in iOS was found in iOS 14.4.2, but still, there is a problem in iOS 14.6.
