Apple released iOS 27.2.1 and iPadOS 27.2.1 on November 9, 2026. The update is available now for supported iPhones and iPads, with the main public release carrying build 24B156.
This is a security-focused update. Apple says it fixes issues affecting AirPlay, Bluetooth, Messages, App Intents, Brotli, CoreUtils, and nearby-device communication.
Important Bluetooth and Messages fixes
Several of the fixes close pairing weaknesses that could be abused by an attacker within Bluetooth range. Apple also corrected a Bluetooth memory-corruption issue and a bug that could allow a malicious Bluetooth device to pair without user interaction.
The Messages fixes address two group-chat privacy problems. One could allow a remote attacker to join an iMessage group and receive its messages, while another could expose earlier messages to somebody added later.
Who can install iOS 27.2.1?
Apple lists iOS 27.2.1 and iPadOS 27.2.1 for iPhone 11 and later, iPad Pro 12.9-inch 4th generation and later, iPad Pro 11-inch 2nd generation and later, iPad Air 4th generation and later, iPad 9th generation and later, and iPad mini 6th generation and later.
Apple also released iOS and iPadOS 26.7.3 for additional older devices and iOS and iPadOS 18.7.12 for the iPhone XS, iPhone XS Max, iPhone XR, and iPad 7th generation. All three branches contain related security fixes.
