Warning Issued To iPhone Users About Key Security Update

Apple’s new iOS 18.5 update will help to protect iPhone users from a potential threat to their device’s security, meaning anyone with an eligible iPhone should update it.

Speaking to The Mirror, UK data expert Safe Data Storage advised all iPhone users to install the new iOS 18.5 update immediately to take advantage of the fix.

“Apple acted fast, but users need to act too,” the data experts told the publication.

“Updating your device is one of the most important things you can do to protect your private information. Tell your parents, your grandparents, your neighbour – anyone with an iPhone. These updates aren’t optional anymore – they’re your first line of defence.” 

Which vulnerability does the update fix?

Apple advises that iOS 18.5 “includes important security fixes and is recommended for all users.” Forbes says this includes 30 possible bugs.

It also targets new Common Vulnerabilities and Exposures (CVEs) like CVE-2025-31251, which Apple says could potentially mean malware that could harm your device could be hidden in media like videos or images. 

″’Processing a maliciously crafted media file may lead to unexpected app termination or corrupt process memory,” Apple wrote.

This was solved with “improved input sanitisation,” their site continues.

No issues with the potential vulnerability have been reported, but it’s still important to update your iPhone (the update is meant for models after and including iPhone XS, or anything released after 2018, Metro reports).

The latest iPad and iPad mini will also need an update. 

How can I update my iPhone?

For all iPhones, you can see whether your device is up to date by going to Settings > General > Software Update. 

If iOS 18.5 is available, select Download and Install. 

If it’s already installed, your phone will say “iOS is up to date.”

Starting with iOS 16.4.1, iPadOS 16.4.1, and macOS 13.3.1, Apple devices are set up to deliver automatic security updates between new software updates, Apple adds.

It does this through Rapid Security Responses, which sometimes need you to restart your device. 

To turn this on in eligible iPhones or iPads, go to Settings > General > Software Update > Automatic Updates. Then, ensure that “Security Responses & System Files” is turned on.
