The March 2022 Android Security Update is rolling out alongside Android 12L for supported Pixel phones

Another month, another security patch. Like clockwork on the first Monday of every month, the latest Android security patch is now available. It should start arriving on third-party devices soon, and it’s now rolling out to all supported Pixel devices. The Google Pixel 6 series again lags behind the rest of the group, after two months of inconsistent releases of Google’s latest flagship series. Moreover, this is also an update to drop the Pixel feature and brings with it the final 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 for the Framework, one for the Media Framework, and ten for the System. Most of the details about each vulnerability are not yet public, so device manufacturers have time to roll out fixes. However, all security patches are classified as “high” risk (except those in the Android runtime), with only one affecting Android 12 (CVE-2021-39708) classified as “critical”.

Google has also released information about the security patch level 03-22-20, which includes fixes for Qualcomm, MediaTek, and Kernel components that may not necessarily apply to all devices.

Pixel Update Bulletin / Functional Update

Below is the complete changelog for Pixel devices which includes fixes and other changes. This is also a feature-dropping update and sees the final and stable Android 12L release for Google Pixel devices. Google Pixel 6 devices will receive the update later this month.
