Description
EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to possible `std::queue`/`std::deque` corruption. The trigger is powermeter public key update and EV session/error events (while OCPP not started). This results in a TSAN data race report and an ASAN/UBSAN misaligned address runtime error being observed. Version 2026.02.0 contains a patch.
