Apple released iOS 16.4 and other software updates on Monday evening. In addition to numerous new features such as new emoji, notifications for web apps and improvements to accessibility features, the updates also include security patches. Specifically, more than 30 security holes are closed.
According to Apple website iOS 16.4, iPadOS 16.4, macOS Ventura 13.3, watchOS 9.4 and tvOS 16.4 fix dozens of security holes that could be exploited by hackers. For example, one of the vulnerabilities related to accessibility could allow third-party apps to access information about users' contacts. Another, more serious vulnerability could allow apps to access sensitive user data. Other vulnerabilities affected parts of the system such as Apple's Neural Engine, Calendar, Camera, CarPlay, Bluetooth, Find My, iCloud, Photos, Podcasts and Safari. Apple also fixed vulnerabilities in the kernel that could lead to the execution of arbitrary code without the user's knowledge.

iOS 16.4, macOS 13.3 & more: Update devices now
Since all Apple operating systems use the same code, some of the patches are applied to iOS, macOS, watchOS and tvOS. Apple has also released updates for older versions of iOS, macOS and Studio Display Firmware with security patches. As you can see, these vulnerabilities can be exploited by hackers to track your data and even collect it without your knowledge. That's why it's important to always update your devices with the latest version of the operating system. You can install updates for iOS, watchOS and tvOS via the Settings app, and updates for macOS can be found in the System Preferences app. (Photo by kanawatTH / Bigstockphoto)
