I'm going to give a general overview of how dm-verity and related things work on Android according to my limited knowledge. Situation might differ on different devices and ROMs. HOW IS DM-VERITY ENFORCED? dm-verity (Verified Boot and AVB) as well as dm-crypt are targets of device-mapper feature of Linux kernel.
