Unauthorized Bluetooth pairing & iMessage snooping patched in iOS 27.2.1
AI-summarised brief · reviewed before publication
Apple released iOS 27.2.1 on Monday, two weeks after iOS 27.2, delivering a focused security‑only update. The patch closes CoreUtils flaws that let malicious Bluetooth devices pair with iPhones and bypass the pairing‑code limit, and it adds stricter state management to stop similar AirPlay pairing exploits. A use‑after‑free bug that could corrupt process memory was also fixed with improved memory handling. In iMessage, the update removes vulnerable code that allowed attackers to infiltrate group chats and read prior messages, correcting an authorization weakness. Additional fixes address an App Intents permission flaw and a Brotli out‑of‑bounds write that could cause memory corruption. Apple lists all changes on its website and urges all users to install the update.
