Apple has released iOS 26.4.2 and iPadOS 26.4.2 updates for iPhone and iPad to address a serious security issue. A previously discovered bug left users vulnerable to hackers.
The unscheduled iOS 26.4.2 and iPadOS 26.4.2 updates have been released for devices starting with the iPhone 11 and newer models, as well as for a number of iPads, including the iPad Pro, iPad Air, iPad mini, and base versions of the latest generation tablets, PhoneArena reports.
Why does Apple recommend installing the update immediately?
The main reason for the urgent release is to address the CVE-2026-28950 vulnerability , which affects the privacy of notifications. The bug allowed the system to retain the content of notifications even after the user manually deleted them.
The problem was related to the login mechanism. The operating system constantly maintains an internal log of actions – a kind of technical diary, where various processes are recorded for stable operation of the device and diagnostics of failures.
Normally, such logs should not contain the text of the messages, but only technical information about the fact of receiving the notification. However, due to a bug, iPhone and iPad stored not only the fact of receiving the message, but also its content in permanent log files .
This created a problem: even if a user deleted a message, its text could remain in the system. Such data could potentially be accessible to malware.
How did you solve the problem?
Apple says the issue was fixed with “improved data redaction.” In fact, the system has new rules about what information can't be stored in logs. This should prevent sensitive message content from being re-entered into service logs.
How do I install the OS 26.4.2 and iPadOS 26.4.2 updates?
To install the update, you need to go to “Settings” → “General” → “Software Update” and download the latest system version.
In addition to the stable security update, Apple also released iOS 26.5 Beta 3. The company continues preparations for WWDC 2026, which starts on June 8. It is there that one of the main presentations of the year is expected – the debut of Siri 2.0.
What is known about the new Siri?
According to preliminary information, the new version of the voice assistant will receive much more powerful artificial intelligence. While Siri currently works on a model with about 8 billion parameters, the new system will allegedly be based on a custom LLM with 1.2 trillion parameters, created on the basis of Gemini.
Siri 2.0 is expected to be much better at understanding complex queries, working with screen context, and performing multi-step tasks. For example, a user will be able to ask Siri to edit a photo, make it brighter, and immediately send it to a relative.
After the WWDC presentation ends on June 8, Apple is expected to immediately open access to iOS 27 Beta 1. The stable version of iOS 27 will traditionally be released to all users in September.
