Apple Ships iOS 26.4.2 to Fix Deleted Notification Leak

The security update closes a loophole that let erased notification data remain on iPhones and iPads.

Overview

  • The updates, released Wednesday, move iPhones and iPads to iOS and iPadOS 26.4.2 with build 23E261.
  • Apple says a Notification Services bug kept notifications marked for deletion on-device, and the update both fixes the logging issue and purges any retained copies.
  • Coverage of recent court testimony reported that the FBI accessed an iPhone’s internal notification database in a case, bringing the retention flaw to Apple’s attention.
  • Apple also issued iOS and iPadOS 18.7.8 for older devices, and it recommends installing these releases for the latest security protections.
  • In parallel, Apple is testing 26.5 betas with Maps Suggested Places, end-to-end encrypted RCS for Android–iPhone chats, and EU-required support for third‑party wearables, with a broader rollout expected in the coming weeks.
