Zero day exploit for Nehelper Wifi Info on iOS 15.0. XPC
endpoint com.apple.nehelper accepts user-supplied parameter
sdk-version, and if its value is less than or equal to 524288, the
com.apple.developer.networking.wifi-info entitlement check is
skipped. This makes it possible for any qualifying application
(e.g. possessing location access authorization) to gain access to
Wifi information without the required entitlement. This happens in
-[NEHelperWiFiInfoManager checkIfEntitled:] in
/usr/libexec/nehelper.
