Apple has rolled out iOS 18.3, urging iPhone users to update their devices immediately to address critical vulnerabilities. The latest update resolves 29 security issues, including one actively exploited flaw, making it a high-priority release.
Critical Vulnerabilities Addressed
Among the vulnerabilities patched in iOS 18.3 is a flaw in CoreMedia, tracked as CVE-2025-24085, which allowed malicious applications to elevate their privileges. Apple acknowledged reports that this issue was actively exploited in earlier iOS versions before iOS 17.2.
Additionally, the update addresses two Kernel-related bugs at the core of the operating system. One of these, CVE-2025-24107, could enable a malicious app to gain root privileges, while the other allows unauthorized code execution with Kernel privileges. A series of flaws in WebKit, the engine behind the Safari browser, were also resolved, including a vulnerability in the Web Inspector that could result in command injection. Other critical fixes include an AirPlay bug (CVE-2025-24137) that allowed remote attackers to execute code and a Passkeys vulnerability that posed a Bluetooth security risk.
Broader Impact and Device Compatibility
The iOS 18.3 update was released alongside iPadOS 17.7.4, though no new updates were provided for iOS 17. Apple has not clarified whether this indicates iOS 17 is unaffected or simply unsupported for newer devices. However, users with devices running iOS 17 are strongly encouraged to upgrade to iOS 18 for enhanced security.
The update is compatible with several Apple devices, including iPhone XS and later models, as well as various iPads, such as the iPad Pro (13-inch and 12.9-inch, 3rd generation and later), iPad Air (3rd generation and later), iPad (7th generation and later), and iPad mini (5th generation and later). Importantly, users of the iPhone 15 series and newer should note that AI capabilities are automatically enabled upon updating and can be adjusted in settings.
Why Immediate Action Is Crucial
Apple’s swift action to patch these vulnerabilities underscores the seriousness of the security threats. With one of the flaws already exploited in real-life scenarios, the update is essential to protect users’ devices from potential attacks.
Users are strongly advised to upgrade by navigating to Settings > Software Update on their devices. The update not only mitigates current threats but also ensures enhanced overall security. With Apple prioritizing user safety, the iOS 18.3 release is a clear reminder to stay updated to safeguard personal data and device functionality.
For iPhone and iPad users, the decision is straightforward: updating to iOS 18.3 is an essential step to ensure your device remains secure against evolving cyber threats.
