It’s been quite a week for Apple, and it’s only Tuesday. The company announced a new iMac with the M4 chip; launched a new Mac mini with M4 and M4 Pro; and, with new operating system updates, launched Apple Intelligence on compatible Macs, iPhones and iPads. But iOS 18.1 and macOS 15.1 weren’t just about Apple Intelligence: In addition to other non-AI featuresThese updates also include fixes for dozens of security vulnerabilities across all devices: 27 of them on iPhone and iPad, and 50 of them on Mac.

Apple doesn’t include security details in its general release notes for software updates, so these fixes tend to go unnoticed. However, company publishes security ratings online shortly after distributing updates to users. We can now see what was included with iOS 18.1 and iPadOS 18.1, as well as macOS 15.1. While a fair number of security fixes are included with these updates (especially macOS 15.1), the good news is that none of these vulnerabilities are zero-day vulnerabilities (security flaws discovered before a patch is ready), and none of them are known to have security vulnerabilities. active exploits in nature. This means that at present, users are not at any major risk if they run updates prior to iOS 18.1 and macOS 15.1.

Still, you should update as soon as possible: Now that details about these vulnerabilities are available, it’s only a matter of time before bad actors figure out how to exploit them.

What flaws did Apple fix?

On macOS, a number of vulnerabilities stood out to me. Apps could potentially access information about your contacts, read sensitive location information through Find My, and leak sensitive kernel state, for example. If you downloaded a malicious image, it could result in a denial of service, an attack that overloads your Mac to make it inaccessible to you. If an attacker had physical access to your Mac, they could bypass the login window during a software update. Safari’s private browsing mode could also leak browsing history.

On iOS and iPadOS, a malicious actor with physical access to your device could view sensitive information, even when it was locked. This includes contacts’ photos, which they could access through a loophole with Siri. A malicious application could execute arbitrary shortcuts without your consent or leak sensitive kernel state. And, as with macOS, private browsing mode on Safari could leak browsing history.

For the full list of fixes, see Apple’s release notes for iOS 18.1 and iPadOS 18.1Or MacOS 15.1.

These fixes aren’t just for Apple’s latest software updates. Additionally, Apple has released security updates for iOS 17.7.1 and iPadOS 17.7.1, macOS Sonoma 14.7.1And macOS Ventura 13.7.1. These updates are intended for users who do not want to update their devices to Apple’s latest operating system, as well as users with older devices who cannot upgrade. The updates contain many of the same security fixes as the latest versions of the operating system. So even if you’re using an older version of iOS, iPadOS, and macOS, you’ll be protected.

It’s not just iPhone, iPad, and Mac either, as Apple has released updates for watchOS 11.1, tvOS 18.1And visionOS 2.1. If you have one of these devices, update it too.

Install the update to protect your iPhone, iPad or Mac from these security vulnerabilities

Again, Apple is not aware of any of these vulnerabilities being actively exploited at this time, but it’s always good to patch them before a bad actor figures out how to take advantage of them.

To update, open Settings (iPhone or iPad) or System Settings (Mac), then go to General > Software Update. Let this page load, then follow the on-screen instructions to download and install the update.
