Check out all the new features and support list for iOS 18.5: Check out the list of iPhones supported, how to download, and more

Apple has officially released iOS 18.5, a critical update that introduces a series of significant security enhancements, making it an essential download for all compatible iPhone users. The update comes as a follow-up to iOS 18.4.1, addressing several bugs and vulnerabilities that had emerged in the previous version. With a total of 33 key improvements included, iOS 18.5 offers a compelling reason for users to upgrade without delay.

Among the most notable updates are fixes within WebKit, the foundational engine that powers the Safari browser. One of the major vulnerabilities patched is CVE-2025-24213, a type confusion flaw uncovered by the Google V8 Security Team, which posed a risk of memory corruption. Resolving such issues reinforces system stability and protects users from potential exploitation during web browsing.

In addition to enhancements within WebKit, iOS 18.5 also secures various core elements of the iOS ecosystem. A notable patch within Core Bluetooth eliminates a loophole that could have been used by malicious applications to access private user data. The update also addresses an issue within iCloud’s document sharing feature, which previously had the potential to activate folder sharing without user consent. Another critical fix involves the mDNSResponder component, where Apple resolved CVE-2025-31222, a flaw that could have allowed attackers to escalate their privileges on the device.

These fixes reflect Apple’s ongoing commitment to user privacy and device security, especially with the company preparing for the integration of its first in-house cellular modem, expected to launch with the upcoming iPhone 16e. All iPhone models that support iOS 18 can get the update, including the iPhone XS, XR, and later models; it also covers the iPhone SE (2nd generation onward) and the entire iPhone 11 through iPhone 16 range.

Users can install iOS 18.5 by going to Settings, then General, and finally Software Update. It is advisable to ensure a stable Wi-Fi connection and sufficient battery level before initiating the update process.
