{"id":"CVE-2025-68132","summary":"EVerest has out-of-bounds read in DZG_GSH01 SLIP CRC parser that can crash powermeter driver","details":"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() \u003c 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.","aliases":["GHSA-79gc-m8w6-9hx5"],"modified":"2026-08-12T15:14:48.243546Z","published":"2026-01-21T18:28:40.763Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68132.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68132.json"},{"type":"ADVISORY","url":"https://github.com/EVerest/everest-core/security/advisories/GHSA-79gc-m8w6-9hx5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68132"},{"type":"FIX","url":"https://github.com/EVerest/everest-core/commit/b8139b95144e3fe0082789b7fafe4e532ee494a1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/EVerest/EVerest","events":[{"introduced":"0"},{"fixed":"227730cd01913f960df3e6f83fef128927a07bed"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2025.12.0"}],"source":"AFFECTED_FIELD"}}],"versions":["2025.10.0","2025.9.0","2025.8.0","2025.7.0","2025.7.0-rc1","2025.6.0","2025.5.0","2025.4.0-rc1","2025.3.0","2025.2.0","2025.1.0-rc2","2025.1.0-rc1","2024.11.0","2024.10.0","2024.9.0-rc1","2024.8.0","2024.7.1","2024.7.0","2024.6.0-rc2","2024.6.0-rc1","2024.5.0","2024.4.0","2024.3.0-rc1","2024.2.0","2024.1.0","2023.12.0","2023.10.0","2023.9.1","2023.9.0","2023.8.0","2023.7.0","2023.6.0","2023.5.0","2023.3.0","2023.2.1","2023.2.0","2023.1.0","2022.12.1","2022.12.0"],"database_specific":{"vanir_signatures":[{"target":{"file":"modules/EVSE/EvseManager/Charger.cpp","function":"Charger::run_state_machine"},"deprecated":false,"digest":{"function_hash":"105791959420441360961467020136404249444","length":17735},"id":"CVE-2025-68132-8d3bacbf","signature_type":"Function","signature_version":"v1","source":"https://github.com/EVerest/EVerest/commit/227730cd01913f960df3e6f83fef128927a07bed"},{"id":"CVE-2025-68132-c8fe96c5","signature_type":"Line","signature_version":"v1","source":"https://github.com/EVerest/EVerest/commit/227730cd01913f960df3e6f83fef128927a07bed","target":{"file":"modules/EVSE/EvseManager/Charger.cpp"},"deprecated":false,"digest":{"line_hashes":["110216529751547046126947211302911956576","186091680927816495345340104376671627738","54993989512986692269835695775072838076","114766109131830359881831328581278020720"],"threshold":0.9}}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68132.json","vanir_signatures_modified":"2026-08-12T15:14:48Z"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
