The iOS 16.4.1 and macOS 13.3.1 patches address a zero-click Wi-Fi exploit that could give attackers complete control over a device without any user interaction. In this article, we’ll explore what these updates entail, why they’re important, and how users can ensure they’re protected.

Apple has recently issued security updates and bug fixes for its operating systems, including iPadOS 16.4.1, macOS Ventura 13.3.1, and iOS 16.4.1.
The updates for iPadOS and iOS do not include any new features, but rather aim to address two major security vulnerabilities. The fixes mentioned in the release notes include:
- The hands emoji showing no skin tone variations
- Siri not responding in certain cases
Apple acknowledges the vocal complaints from users regarding the Siri bug, and assures that it has been resolved. Both security vulnerabilities, which allowed arbitrary code execution and were reportedly being actively exploited, have also been addressed. According to security notes from the company, the vulnerabilities are as follows:

The macOS update addresses the same security vulnerabilities, as well as the issue with skin tones in emojis. It also fixes a bug that affected the feature that allows a user to unlock their Mac with an Apple Watch.
These updates come shortly after the major updates of iOS 16.4 and macOS Ventura 13.3, which added new emojis, improved accessibility features, and fixed several bugs. Apple is expected to release another major update, iOS 16.5, before iOS 17’s release this fall. The company will unveil the features of iOS 17 and macOS 14 at its Worldwide Developers Conference that begins on June 5.
It’s always reassuring to know that companies like Apple are continuously working to ensure the security and safety of their users. With the release of iOS 16.4.1 and macOS 13.3.1, two critical security vulnerabilities have been addressed, leaving users with a more secure operating system. At the same time, it’s important to remember that good security practices don’t just come from software updates; being mindful of the applications you download, using strong passwords, and staying vigilant online can go a long way in keeping your information safe. With its latest update, Apple has done its part to keep you protected – now it’s your turn to do yours. Stay safe!
