A malicious or compromised Redis server, or an attacker in a man-in-the-middle position, can send a crafted RESP response declaring an extremely large array, push, or attribute length, causing the client to attempt a massive heap allocation. The resulting OutOfMemoryError crashes the Vert.x event loop thread, denying service to all connections and verticles sharing that loop.\n\n\n\nThe impacted component is io.vertx:vertx-mysql-client.","categories":["Unclassified"],"product":"Eclipse Vert.x","vendor":"Eclipse Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102465","source_modified_at":"2026-10-15T14:34:24.521Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Eclipse Vert.x","vendor":"Eclipse Foundation","versions":[{"status":"affected","version":"4.0.0","lessThanOrEqual":"4.5.34","versionType":"semver"},{"status":"affected","version":"5.0.0","lessThanOrEqual":"5.0.12","versionType":"semver"},{"status":"affected","version":"5.1.0","lessThanOrEqual":"5.1.9","versionType":"semver"},{"status":"affected","version":"5.2.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","source_modified_at":"2026-10-15T13:11:26Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"maven","name":"vertx-redis-client"},"range":"5.2.0"},{"source":"GitHub Advisory Database","source_url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","source_modified_at":"2026-10-15T13:11:26Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"maven","name":"vertx-redis-client"},"range":">=5.0.0, <=5.1.8"},{"source":"GitHub Advisory Database","source_url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","source_modified_at":"2026-10-15T13:11:26Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"maven","name":"vertx-redis-client"},"range":"<=4.5.34"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","source_modified_at":"2026-10-15T13:11:26Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"maven","name":"vertx-redis-client"},"version":"5.2.1"},{"source":"GitHub Advisory Database","source_url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","source_modified_at":"2026-10-15T13:11:26Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"maven","name":"vertx-redis-client"},"version":"5.1.10"},{"source":"GitHub Advisory Database","source_url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","source_modified_at":"2026-10-15T13:11:26Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"maven","name":"vertx-redis-client"},"version":"4.5.35"}],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00227,"percentile":0.12747,"score_date":"2026-10-23"},"published_at":"2026-10-15T07:27:55.055Z","modified_at":"2026-10-15T14:34:24.521Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102465","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T14:34:24.521Z"},{"source":"GitHub Advisory Database","url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T13:11:26Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102465","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/vert-x3/vertx-redis-client/security/advisories/GHSA-4wf9-p5hg-98w5"},{"source":"CVE List","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/343"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T14:33:50.854450Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T14:34:24.521Z","content_hash":"eeaa084828dbc35623cdefb5e107ae9c0e1d509d51e986b51944999300429a28"}}
