{"id":"CVE-2025-68132","state":"PUBLISHED","title":"EVerest has out-of-bounds read in DZG_GSH01 SLIP CRC parser that can crash powermeter driver","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.","publishedAt":"2026-01-21T18:28:40.763Z","updatedAt":"2026-01-21T19:06:48.136Z","severity":{"score":2.4,"label":"Low","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["EVerest everest-core"],"affected":[{"vendor":"EVerest","product":"everest-core","versions":[{"version":"< 2025.12.0","status":"affected"}]}],"references":["https://github.com/EVerest/everest-core/security/advisories/GHSA-79gc-m8w6-9hx5","https://github.com/EVerest/everest-core/commit/b8139b95144e3fe0082789b7fafe4e532ee494a1"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:09:56.034Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/68xxx/CVE-2025-68132.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-68132","state":"PUBLISHED","datePublished":"2026-01-21T18:28:40.763Z","dateUpdated":"2026-01-21T19:06:48.136Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-12-15T18:05:52.211Z"},"containers":{"cna":{"title":"EVerest has out-of-bounds read in DZG_GSH01 SLIP CRC parser that can crash powermeter driver","descriptions":[{"lang":"en","value":"EVerest is an EV charging software stack.
