CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-68138 impacting linuxfoundation libocpp. Evaluated with CVSS Base Score of 4.7 (MEDIUM).

Original NVD Description

Source: NIST NVD
EVerest is an EV charging software stack, and EVerest libocpp is a C++ implementation of the Open Charge Point Protocol. In libocpp prior to version 0.30.1, pointers returned by the `strdup` calls are never freed. At each connection attempt, the newly allocated memory area will be leaked, potentially causing memory exhaustion and denial of service. Version 0.30.1 fixes the issue.
