CVE-2025-68132
January 21, 2026
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.
