Apple releases iOS and iPadOS 26.4.2 with bug fixes and security patches

New software updates for iPhones and iPads are now rolling out under version 26.4.2 with bug fixes and security patches.

Apple has released new versions of iPadOS and iOS for compatible devices. Version 26.4.2 is now rolling out, bringing unnamed bug fixes and security updates. Apple is not saying what was fixed in today's release. The official changelog only says "This update provides bug fixes and security updates for your iPhone."

You can update your device to iOS or iPadOS 26.4.2 by heading to Settings > General > Software Update. Your iPhone or iPad will check for updates and offer to download and install version 26.4.2. The exact update size depends on your device, but expect to download and install over 500 MB.

According to the official documentation, iOS and iPadOS 26.4.2 fix a bug flagged as CVE-2026-28950 that could lead to notifications "marked for deletion" remaining on the device.

iOS and iPadOS 26.4.2 are available on iPhone 11 and later, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 8th generation and later, and iPad mini 5th generation and later. However, the security issue also affects devices that do not support iOS / iPadOS 26. For these, Apple also released iOS 18.7.8 and iPadOS 18.7.8. These do not contain new features and only bring fixes for CVE-2026.28950.

Later this year, Apple is expected to ship iOS / iPadOS 26.5 ahead of the iOS 27 announcement at WWDC 2026. Version 26.5. will bring changes to Apple Maps, messaging, and other changes. In June, Apple is hosting its annual developer conference, where it is expected to talk about this year's "27" releases, improved Siri, and more.
