Summary
EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to C++ UB (potential memory corruption). This is triggered by an MQTT `everest_external/nodered/{connector}/cmd/switch_three_phases_while_charging` message and results in `Charger::shared_context` / `internal_context` accessed concurrently without lock. Version 2026.02.0 contains a patch.
