Apple today released iOS 26.4.2 and iPadOS 26.4.2 software updates for the iPhone and iPad, respectively. The minor updates come two weeks after Apple’s release of iOS 26.4.1 and iPadOS 26.4.1.
The new software can be downloaded on compatible iPhones and iPads by going to Settings -> General -> Software Update.
According to Apple’s release notes, the software updates contain unspecified bug fixes and security updates.
The iOS 26.4.2, iPadOS 26.4.2, iOS 18.7.8, and iPadOS 18.7.8 updates that Apple released today address a security vulnerability that the FBI recently took advantage of to extract Signal message previews from an iPhone even after the app was deleted.
As reported by MacRumors, a flaw with notification services allowed notifications that were supposed to be deleted to remain on an iPhone or iPad. Apple says it fixed the logging issue with improved data redaction.
Recent court testimony revealed that the FBI was able to access the internal notification database on an iPhone involved in a case, providing law enforcement with access to message previews. The iPhone in question was set to display the content of Signal messages on notifications on the device’s Lock Screen, and that feature caused the iPhone to store message content.
While the defendant in the case had deleted the Signal app and had his Signal messages set to disappear, the messages remained in its database long enough for the FBI to access them.
Apple is currently beta testing iOS 26.5 and iPadOS 26.5, which will likely launch sometime this month or next.
