CVE-2023-35674Android — an app that starts itself from the background

A logic error in the Android window code lets an app launch an activity while it is in the background, which raises what it can do. No extra rights are needed and the user has to do nothing at all.

YOUR NEXT MOVE

Install the September 2023 Android security patch level. On handsets that will never receive it, remove apps you do not need — one already installed is the precondition.
