CVE-2026-33009

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.

Summary		(es) EVerest es una pila de software de carga de vehículos eléctricos. Las versiones anteriores a la 2026.02.0 tienen una condición de carrera de datos que conduce a un comportamiento indefinido (UB) de C++ (potencial corrupción de memoria). Esto se activa mediante un mensaje MQTT 'everest_external/nodered/{connector}/cmd/switch_three_phases_while_charging' y resulta en que 'Charger::shared_context' / 'internal_context' se acceden concurrentemente sin bloqueo. La versión 2026.02.0 contiene un parche.
