Apple releases iOS 27.2.1 with iMessage and Bluetooth security fixes
Apple released iOS 27.2.1 for iPhone users on Monday, two weeks after iOS 27.2 arrived.
The smaller update follows a major release and includes bug fixes and security updates, but no new features.
It blocks attackers from joining iMessage group chats and reading messages sent before they joined.
It also fixes flaws that could let malicious Bluetooth devices pair with iPhones without the user’s involvement.
Other patches address an AirPlay pairing-code flaw, an issue that could expose sensitive data to apps, and bugs that could cause memory corruption.
Apple recommends users install the update to receive these protections; iPadOS 27.2.1 was also released with similar fixes.
Apple released iOS 27.2.1 on Nov. 9 with security fixes for iMessage, Bluetooth and other issues.
The iMessage fixes prevent attackers from joining group chats and reading messages sent before they joined.
Bluetooth fixes address unauthorized pairing and a flaw that could let a nearby attacker corrupt process memory.
Apple also released iPadOS 27.2.1 and macOS 27.2.1.
Apple did not say the vulnerabilities had been exploited in the wild.
