Apple released tvOS 27.2.1 on November 13, bringing Siri AI to Apple TV 4K models from the second generation onward and fixing seven security vulnerabilities in the platform. The update extends the new assistant beyond the latest fourth-generation hardware, while also addressing flaws affecting wireless pairing, Bluetooth and other system components.
Apple’s Siri AI requirements confirm that the feature works on Apple TV 4K (2nd generation and later) running tvOS 27.2.1. Users also need a nearby paired iPhone or iPad with Siri AI enabled. The device language and Siri language must match one of Apple’s supported languages: English, French, Japanese, Korean, Portuguese or Spanish.
Apple’s security bulletin for tvOS 27.2.1 lists seven vulnerabilities fixed in the release. They are CVE-2026-113968, CVE-2026-113963, CVE-2026-113970, CVE-2026-111497, CVE-2026-113965, CVE-2026-113964 and CVE-2026-113969. Apple says the issues affect AirPlay, App Intents, Bluetooth, brotli, CoreUtils and rapportd.
The documented impacts include an attacker within Bluetooth range bypassing AirPlay pairing-code limits, Bluetooth memory corruption, an app gaining access to sensitive user data, and a malicious Bluetooth device establishing a pairing without user interaction. Another flaw could let an attacker on the same network bypass AirPlay pairing-code limits. Apple’s advisory does not identify any of the seven vulnerabilities as actively exploited in attacks.
Several of the AirPlay and Bluetooth weaknesses also appear in Apple’s recent mobile software fixes, including the issues described in Abijita’s coverage of Apple’s AirPlay and Messages security updates.
Apple first outlined the broader Siri AI rollout at WWDC, describing a redesigned assistant with personal-context understanding and wider system actions.

The tvOS 27.2.1 release now extends that experience to supported older Apple TV 4K models, subject to Apple’s device and language requirements, as detailed in its announcement of the next generation of Apple Intelligence and Siri AI.
