Official description
EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to possible `std::map<std::queue>` corruption. The trigger is CSMS GetLog/UpdateFirmware request (network) with an EVSE fault event (physical). This results in TSAN reports concurrent access (data race) to `event_queue`. Version 2026.2.0 contains a patch.
