Earlier this week, the company pushed out the iOS 16.5.1 (a) to iPhones, but the update was pulled shortly after following reports that it broke the Safari browser when used to visit websites like Facebook, Instagram, and Zoom. The update was to fix a security bug with the WebKit browser engine that was being actively exploited in the wild, so it was considered critical.
And if you thought that we'd already had an iOS 16.5.1 update, you'd be right. This was released at the end of June and also focused on WebKit bugs.
Well, now we have iOS 16.5.1 (c) (along with iPadOS 16.5.1 (c) for the iPad), which hopefully fixes the WebKit issue without breaking the Safari browser.
This is how Apple describes this update: "Rapid Security Responses iOS 16.5.1 (c) and iPadOS 16.5.1 (c) include the security content of Rapid Security Responses iOS 16.5.1 (a) and iPadOS 16.5.1 (a) and fix an issue that prevents some websites from displaying properly."
