CVE-2025-68132— EVerest has out-of-bounds read in DZG_GSH01 SLIP CRC parser that can crash powermeter driver
Quick assessment
Affected
EVerest everest-core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
everest-core是EVerest开源的一个电动汽车充电软件堆栈的主要部分。 everest-core 2025.12.0之前版本存在缓冲区错误漏洞，该漏洞源于DZG_GSH01功率计SLIP解析器中的is_message_crc_correct函数未检查至少存在两个字节，可能导致越界读取和pop_back下溢，引发进程崩溃。

Vulnerability Title
EVerest has out-of-bounds read in DZG_GSH01 SLIP CRC parser that can crash powermeter driver
Source: CVE Program / CVE List V5
Vulnerability Description
EVerest is an EV charging software stack. Prior to version 2025.12.0, `is_message_crc_correct` in the DZG_GSH01 powermeter SLIP parser reads `vec[vec.size()-1]` and `vec[vec.size()-2]` without checking that at least two bytes are present. Malformed SLIP frames on the serial link can reach `is_message_crc_correct` with `vec.size() < 2` (only via the multi-message path), causing an out-of-bounds read before CRC verification and `pop_back` underflow. Therefore, an attacker controlling the serial input can reliably crash the process. Version 2025.12.0 fixes the issue.
