Wi-Fi bug fixed in iOS 14.7
The Wi-Fi issue was reported almost a month ago and was fixed with iOS 14.7 beta 5 update. When users tried to connect to a Wi-Fi network named “%p%s%s%s%s%n.”, it would disable Wi-Fi connectivity and the only fix was to reset network settings.
Here are the details of the annoying Wi-Fi bug and how Apple fixed it.

CVE-2021-30800: vm_call, Nozhdar Abdulkhaleq Shukri
You can read details of all the other security fixes in iOS 14.7 and iPadOS 14.7 here. As always, a few of the security bug reports were from the Google Project Zero team. Fortunately, no issue is listed as actively exploited in the wild, unlike the issues that Apple has fixed over the past many releases for iOS 14.
Apple has also fixed almost 35 security issues in macOS Big Sur 11.5 which affected WebKit, Kernel, Graphics Drivers, AppKit, and more. macOS Catalina and macOS Mojave also received many of these security updates.
watchOS 7.6 and tvOS 14.7 have also received more than 20 security fixes each for many of the same issues such as WebKit and Kernel flaws, including others.
In case you are still on an older version of Apple’s operating systems, we highly recommend that you update due to the number of security flaws that have been patched.
