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."}], "lastModified": "2026-05-11T15:22:48.177", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:osrg:gobgp:4.4.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6EF1E97F-CA8A-45E6-B115-E9BD4EC8B36F"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
