On April 16th, Apple released iOS 18.4.1, addressing two zero-day vulnerabilities already exploited by hackers. Apple stated on its website about each exploit: “Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on iOS.” The vulnerabilities affect Core Audio (CVE-2025-31200) and Return Pointer Authentication Code (RPAC, CVE-2025-31201). Core Audio, an API for processing sound on Apple’s operating systems, had a flaw (CVE-2025-31200) that allowed attackers to execute code via a “maliciously crafted media file” during audio stream processing. RPAC, an iOS security feature to prevent code manipulation, was bypassed by the CVE-2025-31201 exploit, enabling attackers with “arbitrary read and write capability” to evade Pointer Authentication. These issues also impact other Apple devices, including certain iPads, Apple TVs, Apple Vision Pro, and Macs running macOS Sequoia. Apple has released updates for each device’s operating system to patch these exploits. ‎ MacDailyNews Take: On your iPhone: Settings > General > Software Update > Update Now.
