On April 16, Apple released critical updates for several of its platforms, including iOS 18.4.1, iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, and visionOS 2.4.1. These updates primarily target security vulnerabilities and performance improvements rather than introducing new features. Apple strongly recommends that all users install them promptly to ensure device safety.
Serious Threats Addressed
According to Apple’s security notes, the updates fix two significant vulnerabilities. The first, found in CoreAudio, could allow a maliciously crafted media file to execute arbitrary code. Apple and Google’s Threat Analysis Group identified this flaw, which has already been exploited in sophisticated attacks.
The second issue affects RPAC, a system that helps secure memory. An attacker could bypass Pointer Authentication, giving them read and write access to device memory. This vulnerability also has been observed in real-world attacks. The security flaws are listed under CVE-2025-31200 and CVE-2025-31021.
How to Update Your Devices
Updating to the latest software is simple. iPhone and iPad users can navigate to Settings > General > Software Update. Mac users should go to System Settings > General > Software Update. For those who prefer not to update manually, devices can be set to download and install updates automatically.
A Routine but Vital Move
While the update version numbers—such as iOS 18.4.1 and macOS 15.4.1—suggest minor changes, they carry essential patches that protect users from active security threats. As cyberattacks become more advanced, timely updates like these play a crucial role in safeguarding personal data.
