The race between concurrent accesses to Charger::shared_context and internal_context introduces undefined behaviour that can result in memory corruption, corrupting the charger state. The affected code lacks proper synchronization mechanisms. Consequently, an attacker who can inject a crafted MQTT message may cause the charger to enter an inconsistent or erroneous state, potentially leading to denial of service, incorrect operation, or other integrity violations.", "risk_and_exploitability": "The CVSS score of 8.2 indicates a high\u2011severity vulnerability.

The vulnerability can be exploited if an attacker controls or can influence the MQTT traffic that the charger consumes."}}}}, "created": "2026-03-27T08:33:46.609316+00:00", "updated": "2026-03-27T09:26:12.463303+00:00", "vendors": ["everest", "everest$PRODUCT$everest-core"]}
