September 2022 Android security update rolls out to supported Google Pixel phones

Google has a tradition of releasing new updates for its Pixel devices as well as publishing a new Android Security Bulletin on the first Monday of each month. However, given that yesterday was Labor Day in the U.S., the company delayed this month’s announcement until today. The Android Security Bulletin for September 2022 has now been made public, and a new security update is rolling out for Pixel phones.

September 2022 Android Security Update Bulletin

The Android Security Bulletin for the month of September 2022 details multiple security vulnerabilities ranging in severity from high to critical. The 2022-09-01 security patch level addresses vulnerabilities discovered in Android components, including the Android runtime, Framework, System, and several Project Mainline modules. Meanwhile, the 2022-09-05 security patch level addresses vulnerabilities discovered in not only Android’s kernel but also in some SoC-specific components.


As we’ve seen in the past, many of the disclosed vulnerabilities don’t offer additional documentation that explains what is affected and how the patch addresses the issue. You can read up on how monthly Android security updates work here.

Pixel Update Bulletin/Functional Update

In addition to providing information about vulnerabilities in the general Android Security Update Bulletin, Google has also patched additional vulnerabilities in the security update rolling out for Pixel devices. Unfortunately, this month doesn’t coincide with a new Pixel Feature Drop. All in all, the latest monthly update is comparatively less exciting than last month’s update, which brought Android 13 to the stable channel.

The full changelog is below:
