A malicious or compromised MySQL server, or an attacker with man-in-the-middle positioning, can send a crafted result set packet with an extremely large column count, causing the client to attempt a massive heap allocation. The resulting OutOfMemoryError crashes the Netty event loop thread, causing a complete denial of service for all connections and verticles in the Vert.x application.\nThe impacted component is io.vertx:vertx-mysql-client.\nhttps://www.cve.org/CVERecord?id=CVE-2026-102466https://github.com/eclipse-vertx/vertx-sql-client/security/advisories/GHSA-9jxp-x3fr-ffqhhttps://gitlab.eclipse.org/security/cve-assignment/-/work_items/342#eclipse #EclipseFoundation #EclipseVert.x#CVE_2026_102466#bot", "url": "https://infosec.exchange/users/cve/statuses/117444009514172996"}, {"timestamp": "2026-10-15T09:17:15Z", "date_only": false, "value": "2026-10-15T09:17:15Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-WPJJ-864Q-GGC9", "record": "GHSA-WPJJ-864Q-GGC9", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-15T09:17:15.427Z", "date_only": false, "value": "2026-10-15T09:17:15.427", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-102466", "record": "FKIE_CVE-2026-102466", "field": "published"}, {"timestamp": "2026-10-15T09:30:34Z", "date_only": false, "value": "2026-10-15T09:30:34Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-WPJJ-864Q-GGC9", "record": "GHSA-WPJJ-864Q-GGC9", "field": "published"}, {"timestamp": "2026-10-15T09:30:34Z", "date_only": false, "value": "2026-10-15T09:30:34Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-WPJJ-864Q-GGC9", "record": "GHSA-WPJJ-864Q-GGC9", "field": "modified"}, {"timestamp": "2026-10-15T14:23:56.020Z", "date_only": false, "value": "2026-10-15T14:23:56.020086Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-102466", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-15T14:23:56.020Z", "date_only": false, "value": "2026-10-15T14:23:56.020086Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-102466", "record": "FKIE_CVE-2026-102466", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-15T14:24:55.316Z", "date_only": false, "value": "2026-10-15T14:24:55.316Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-102466", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-15T14:24:55.316Z", "date_only": false, "value": "2026-10-15T14:24:55.316Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-102466", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-15T15:17:19.190Z", "date_only": false, "value": "2026-10-15T15:17:19.190", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-102466", "record": "FKIE_CVE-2026-102466", "field": "lastModified"}]}
