Apple has released an urgent security warning for iPhone users worldwide, advising them to update their devices immediately to address two critical zero-day vulnerabilities that are actively being exploited. These flaws, identified as CVE-2025-43529 and CVE-2025-14174, are present in WebKit, the browser engine powering Safari and all iOS browsers. If exploited, they could allow attackers to execute arbitrary code remotely or cause memory corruption by simply luring users to malicious websites, potentially leading to device compromise and data theft. The critical updates are available in iOS 26.2 for iPhone 11 and newer models, as well as corresponding patches for other Apple operating systems like iPadOS 26.2, macOS Tahoe 26.2, tvOS 26.2, watchOS 26.2, visionOS 26.2, and Safari 26.2. A significant concern highlighted by security experts and multiple news outlets, including Forbes and NDTV Profit, is the slow adoption rate of iOS 26. This delay leaves hundreds of millions of iPhones, specifically iPhone 11 and newer, exposed to these sophisticated attacks, as Apple has reportedly ceased providing security patches for these particular vulnerabilities on older iOS 18 versions. While the original Forbes headline emphasized a 'restart,' the definitive and most crucial action for users to protect themselves is to perform a full software update to the latest available iOS version. These targeted attacks are often initially aimed at high-profile individuals, but the threat can quickly expand to broader user bases. Therefore, all eligible users are strongly urged to update their devices without delay.
