Vbmeta, short for verified boot metadata, is a component of the Android boot process that contains information about the verified boot state of the device. It is a part of the boot image that is verified by the bootloader to ensure that the boot image has not been tampered with. The vbmeta structure contains a hash of the boot image, which is compared with the actual boot image to verify its authenticity. If the hashes do not match, the bootloader will refuse to boot the device. This verification process ensures that the operating system has not been compromised, providing a secure boot process.
