Description
EVerest is an EV charging software stack. Prior to versions to 2026.02.0, ISO15118_chargerImpl::handle_update_energy_transfer_modes copies a variable-length list into a fixed-size array of length 6 without bounds checking. With schema validation disabled by default, oversized MQTT Cmd payloads can trigger out-of-bounds writes and corrupt adjacent EVSE state or crash the process. Version 2026.02.0 contains a patch.
