Apple has updated its latest iOS 16 to version iOS 16.5 rather recently. Even more recently, they have just released the 16.5.1 version of the iOS 16.5. Apparently, they have just updated the 16.5.1 again. While being only a 2.7MB update, it is a critical one.
Apple labels this as one of their Rapid Security Response updates for their software. Alongside the Apple iPhone, the iPad is also getting the Rapid Security Response for the iPadOS 16.5.1. As per the release notes, the iOS 16.5.1(a) update is available for iPhones with iOS 16.5.1. But it is not just the iPhone and iPad that is getting a security update. At the same time, Apple is releasing security updates for MacOS Ventura [13.4.1 (a)] and Safari (16.5.2).
The thing about Apple’s security updates is that they can be rather vague in their description. According to their release notes, the update addresses “web content processing that may lead to arbitrary code execution”. According to Apple as well, there has been reports on the issue being heavily exploited, hence the need for iOS 16.5.1 (a) update. The release notes says that the update will bring “improved checks” to address the issue, whatever that means.
Rapid Security Response updates are important updates, they tend to patch security issues that has been reported or found. That also means that it is recommended that users on the latest iOS to check for their updates if they have not been updated yet. It is a relatively small update too, which also means that you might not have too much trouble or too long of a downtime with your iPhone when you do update your device. Once updated, your iPhone will request that you restart your device. Once you do so, your device should display iOS 16.5.1 (a) instead of the regular iOS 16.5.1 when you check its software version.
