In version 4.4.0, an unauthenticated remote BGP peer can trigger a fatal panic in GoBGP by sending a specially crafted BGP UPDATE message. When the server receives a message with inconsistent attribute lengths, it improperly handles the internal state transition to a \"withdraw\" action, leading to a nil pointer dereference in the AdjRib.Update function. This causes the entire GoBGP process to crash, resulting in a complete loss of service availability. This issue has been patched in version 4.5.0.","state":0,"publishedAt":"2026-05-07T12:16:18.18+00:00","modifiedAt":"2026-10-26T22:10:00.163+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/osrg/gobgp/releases/tag/v4.5.0","https://github.com/osrg/gobgp/security/advisories/GHSA-p3w2-64xm-833j"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-42285","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-476"],"productCriteria":["cpe:2.3:a:osrg:gobgp:4.4.0:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-05-07T12:16:18.180","lastModified":"2026-10-26T22:10:00.163"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
