CVE-2022-3917Public exploit

Data disclosure via unauthenticated bootloader pull command

Published Dec 14, 2022 · Updated Apr 17, 2025

Improper bootloader access control in Motorola Mobility Moto e20 before RONS31.267-38-8 allows physically proximate attackers to read RAM data. An undocumented fastboot oem pull subcommand accepts a partition name or memory address and size, then streams the requested bytes to a connected host without authorization. Physical possession and a USB-connected host are required; rebooting into bootloader mode exposes residual app data, while encrypted user data remains protected by default.
