Apple Fixes Several Vulnerabilities, Including Safari Vulnerability Exploited as Chrome 0-Day

Apple released a comprehensive set of security updates on July 29, 2025, addressing vulnerabilities across its entire ecosystem of devices and operating systems.

The latest updates include critical patches for iOS, iPadOS, macOS, watchOS, tvOS, and visionOS, with particular attention to Safari browser security issues that have been linked to broader web browser vulnerabilities.

Apple’s most recent security release cycle demonstrates the company’s commitment to maintaining robust security across all platforms.

The July 29, 2025 updates include comprehensive coverage across multiple device categories:

• iOS and iPadOS Updates: iOS 18.6 and iPadOS 18.6 for newer devices, targeting iPhone XS and later models, as well as various iPad generations.
  
• Legacy Device Support: iPadOS 17.7.9 specifically addresses iPad Pro 12.9-inch 2nd generation, iPad Pro 10.5-inch, and iPad 6th generation models.
  
• macOS Multi-Version Updates: macOS Sequoia 15.6, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7 all received security patches simultaneously.
  
• Wearable and Entertainment Devices: watchOS 11.6 for Apple Watch Series 6 and later, tvOS 18.6 for all Apple TV models.
  
• Vision Pro Updates: visionOS 2.6 for Apple Vision Pro received security enhancements.

This parallel update strategy ensures that users on different operating system versions maintain comparable security protections.

Apple’s comprehensive approach demonstrates that no device category is overlooked in the company’s security maintenance cycle, extending protection from flagship iPhones to specialized devices like the Apple Vision Pro.

Safari Vulnerability

Safari has been a focal point in recent security updates, with the browser receiving multiple patches throughout 2025.

The pattern of Safari updates indicates Apple’s awareness of the browser’s critical role in user security, particularly as web-based attacks become increasingly sophisticated.

Safari 18.5 was released on May 12, 2025, for macOS Ventura and macOS Sonoma, followed by Safari 18.4 on March 31, 2025.

The Safari security updates are particularly significant given the interconnected nature of modern web browser vulnerabilities.

When security researchers discover exploits that affect one browser engine, similar vulnerabilities often exist across different browsers due to shared web standards and similar implementation approaches.

Apple’s proactive approach to Safari security updates suggests the company is working to address vulnerabilities that could potentially impact users across multiple browsing platforms.

Security Update Schedule

Apple’s security released schedule demonstrates a systematic approach to vulnerability management, with major updates typically released monthly and emergency patches deployed as needed.

The company’s policy of not disclosing security issues until patches are available protects users while fixes are being developed and tested.

This approach, while sometimes criticized for lack of transparency, helps prevent malicious actors from exploiting known vulnerabilities before fixes are widely deployed.

The security update list reveals Apple’s support for legacy devices, with updates continuing for older iOS and iPadOS versions including iOS 16.7.11, iOS 15.8.4, and their iPadOS counterparts.

This extended support ensures that users who cannot upgrade to the latest hardware versions still receive critical security protections.

Apple emphasizes that keeping software up to date is “one of the most important things you can do to maintain your Apple product’s security”.

The company provides detailed instructions for updating each device category and notes that for iOS, iPadOS, tvOS, watchOS, and visionOS, downgrading to previous versions is not possible after installing updates.
