The other day Apple released the iOS 10.3 update which is one of the company’s more major updates to date ahead of iOS 11. Now one of the changes that Apple made to iOS 10 with the update is patch a couple of security flaws, but it seems that they might have missed one, or it did not get patched in time for the release.

If you’ve received a notification on your phone that asks you to update to iOS 10.3.1, you probably should because this particular update apparently patches a WiFi flaw on iOS devices. While Apple does not specify what the patch did, the changelog reads, “includes bug fixes and improves the security of your iPhone or iPad”.

However it was only after digging through the security document that it was revealed that the update patches a WiFi security flaw that was discovered by one of Google’s Project Zero engineers. For those curious about the flaw, basically it allows hackers to execute arbitrary code on the WiFi chip.

Whether or not this flaw has been exploited already is unclear, but judging from the seemingly lack of reports we’re guessing no. However given that it has now been sort of revealed, you might want to patch it lest there are hackers out there who are counting on users who have yet to update their devices.
