Prior to version 1.16.9, through a flaw in the ECIES cryptography implementation, an attacker may be able to extract bits of the p2p node key. The issue is resolved in the v1.16.9 and v1.17.0 releases of Geth. Geth maintainers recommend rotating the node key after applying the upgrade, which can be done by removing the file `<datadir>/geth/nodekey` before starting Geth.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-203"],"references":["https://github.com/ethereum/go-ethereum/security/advisories/GHSA-m6j8-rg6r-7mv8"],"products":["ethereum:go_ethereum"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26315","score":0.00507,"percentile":0.43313,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m6j8-rg6r-7mv8","url":"https://osv.dev/vulnerability/GHSA-m6j8-rg6r-7mv8","summary":"Go Ethereum Improperly Validates the ECIES Public Key in RLPx Handshake","modified":"2026-02-28T06:26:19.014657Z","packages":[{"ecosystem":"Go","name":"github.com/ethereum/go-ethereum","purl":"pkg:golang/github.com/ethereum/go-ethereum","ranges":["<1.16.9"],"fixed":["1.16.9"]}]},{"id":"GO-2026-4511","url":"https://osv.dev/vulnerability/GO-2026-4511","summary":"Go Ethereum Improperly Validates the ECIES Public Key in RLPx Handshake in github.com/ethereum/go-ethereum","modified":"2026-02-24T23:41:04.631464Z","packages":[{"ecosystem":"Go","name":"github.com/ethereum/go-ethereum","purl":"pkg:golang/github.com/ethereum/go-ethereum","ranges":["<1.16.9"],"fixed":["1.16.9"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
