Apple releases iOS 18.4.1 update, fixes major security flaws

Apple has released the iOS 18.4.1 update to address two significant zero-day security vulnerabilities affecting iPhones and iPads. The update patches flaws in CoreAudio, which could allow hackers to execute code by processing malicious audio files, and in the RPAC framework, which could let attackers bypass Pointer Authentication and potentially steal user data. These vulnerabilities have reportedly been exploited in highly sophisticated attacks targeting specific individuals, prompting Apple and security experts to urge immediate installation of the update. In addition to these critical security fixes, iOS 18.4.1 resolves various bugs, including issues with CarPlay connectivity, battery drainage, and deleted apps reappearing on devices. Apple has intentionally withheld detailed information about the vulnerabilities to give users time to update before attackers can exploit the flaws further. Users are strongly encouraged to update their devices promptly to ensure optimal security and device performance.
