March 2022 Android security update rolls out alongside Android 12L to supported Pixel phones

Another month, another security patch. Like clockwork on the first Monday of each month, the latest Android security patch is now available. It should start arriving on third-party devices soon, and it’s rolling out now to all supported Pixel devices. The Google Pixel 6 series is yet again behind the rest of the pack, after a couple of months of inconsistent releases for Google’s latest flagship series. What’s more, this is also a Pixel feature drop update 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 in Framework, one in Media Framework, ten in System. Most of the details about each vulnerability aren’t public yet, so device manufacturers have time to roll out fixes. However, all the security patches are labeled as “high” severity (bar the one in Android runtime), with one that only affects Android 12 (CVE-2021-39708) marked as “critical.”

XDA VIDEO OF THE DAY

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 Update

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