Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

iOS 26.0.1 was the first public maintenance update after iOS 26. Apple documented connectivity failures on the iPhone 17 family, a cellular-registration problem affecting a small number of devices, and unexpected image artifacts under some lighting conditions.[1]

The release also corrected blank custom-tinted icons and a VoiceOver state failure. Its security advisory identifies a separate FontParser bounds issue that could corrupt process memory when a device handled a malicious font.[2][1]
