DescriptionGitHub Advisory

EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to std::map<std::optional> concurrent access (container/optional corruption possible). The trigger is an EV SoC update with powermeter periodic update and unplugging/SessionFinished state. Version 2026.2.0 contains a patch.

AnalysisAI

Concurrent access to std::map<std::optional> in EVerest-Core versions prior to 2026.02.0 causes a data race condition that can corrupt container state during simultaneous EV state-of-charge updates, power meter periodic updates, and session termination events, resulting in denial of service of the EV charging stack. EVerest-Core (cpe:2.3:a:everest:everest-core) is the affected product, with patched version 2026.02.0 available. No public exploit code has been identified at time of analysis, and this vulnerability is not confirmed actively exploited; however, the condition is readily triggerable through normal charging operations combining multiple concurrent data sources.

Technical ContextAI

EVerest is an open-source EV charging software stack that manages real-time state across multiple concurrent data streams including vehicle state-of-charge telemetry, AC/DC power meter readings, and session lifecycle events. The vulnerability is rooted in CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization), specifically a race condition within std::map<std::optional> container operations. The affected product is identified via CPE cpe:2.3:a:everest:everest-core:*:*:*:*:*:*:*:*. The race occurs when three concurrent operations interact: (1) EV SoC update threads writing vehicle state, (2) power meter periodic update threads reading/writing meter data, and (3) session lifecycle transitions (unplugging or SessionFinished state changes). Without proper synchronization primitives (mutexes, atomics, or lock-free structures), concurrent map access results in undefined behavior, including iterator invalidation, double-deletion, or memory corruption of the optional wrapper itself.

RemediationAI

Upgrade EVerest-Core to version 2026.02.0 or later as released by the EVerest project. For deployments unable to immediately patch, implement network-level isolation of charging station management interfaces and power meter communication streams to reduce the likelihood of concurrent data stream interference, though this does not eliminate the underlying race condition. Monitor system logs for unexpected session terminations or availability drops, which may indicate exploitation attempts or trigger conditions. Deploy the upgrade at the earliest maintenance window, as the patch directly addresses the synchronization defect without known side effects.
