Vulnerability Data
EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race (C++ UB) triggered by an A 1-phase ↔ 3-phase switch request (`ac_switch_three_phases_while_charging`) during charging/waiting executes concurrently with the state machine loop. Version 2026.02.0 contains a…

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including concurrency and thread-safety testing) would have detected the data race between ac_switch_three_phases_while_charging and the state-machine loop before release.
Requiring secure development processes and tools (static analysis, thread sanitizers, formal methods for shared-state) directly prevents introduction of C++ data races such as the one described.
Software integrity verification can detect anomalous behavior or crashes resulting from the undefined behavior triggered by the race condition during charging.

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

Security testing can detect race conditions, but does not prevent them at design or coding time.
Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.
Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.
Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.
Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.
Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
