What is CVE-2025-68132?
CVE-2025-68132 is a low-severity denial of service vulnerability in everest-core, published on 21 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-125
