Android Automotive OS Update Bulletin

Monthly device updates are an important tool to keep Android users safe and protect their devices. This page contains the available Android Automotive OS (AAOS) Security Bulletins which supplement the Android Security Bulletins with additional security patches, providing fixes for possible issues affecting devices running AAOS.


AAOS devices start receiving OTA updates on the same day the monthly bulletin is released. Patches listed in the AAOS security bulletins can come from various sources, including: the car manufacture, the Android Open Source Project (AOSP), the upstream Linux kernel, and system-on-chip (SOC) manufacturers.
