Monthly device updates are an important tool to keep Android users safe and protect their devices. This page contains the available Android Security Bulletins, which provide fixes for possible issues affecting devices running Android.

Sources Fixes listed in the public bulletin come from various different sources: the Android Open Source Project (AOSP), the upstream Linux kernel, and system-on-chip (SOC) manufacturers. For device manufacturers: Android platform fixes are merged into AOSP 24–48 hours after the security bulletin is released and can be picked up directly from there. Upstream Linux kernel fixes are linked to directly from the bulletin on release and can be picked up from there. Fixes from SOC manufacturers are available directly from the manufacturers.
