iOS 26.4.2 Patches Flaw That Let FBI Extract Deleted Signal Messages

Apple released iOS 26.4.2 and iPadOS 26.4.2 to fix a notification privacy flaw.

The bug could leave retained notification data accessible even after messages or the app were deleted.

Court testimony said the FBI used the flaw to recover Signal message previews from an iPhone.

The update matters because it helps protect sensitive private communications stored in notification logs.
