March 2022 Android security update released for Pixel phones supported with Android 12L

XDA Developers

Another month, another security patch. Like clockwork on the first Monday of every month, the latest Android security patch is now available. It should be rolling out to third-party devices soon, and it’s now rolling out to all supported Pixel devices. After a few months of inconsistent releases for Google’s latest flagship series, the Google Pixel 6 series is again behind the rest of the pack. What’s more, this is also a Pixel feature drop update and brings with it the last stable release of Android 12L.

March 2022 Android Security Update Bulletin

The 2022-03-01 security patch level includes one for the Android runtime, six in the framework, one in the media framework, ten in the system. Most of the details about each vulnerability are not yet public, so device makers have time to roll out fixes. However, all security patches are labeled as “high” severity (once in the Android runtime), with only Android 12 (CVE-2021-39708) marked as “critical”.

Google has also released information about the 2022-03-05 security patch level, which includes fixes for Qualcomm, MediaTek and kernel components that may not necessarily apply to all devices.

Pixel Update Bulletin/Functional Updates

The full changelog for Pixel devices is below which includes improvements and other changes. This is also a feature drop update and sees the arrival of the final, stable Android 12L build for Google Pixel devices. Google Pixel 6 devices will receive the update later this month.
