CVE-2026-44505

Estado: AplazadaMedia (5.3)—

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. network-libp2p handles kad get-record query progress in handle_dht_get (network-libp2p/src/swarm.rs). Prior to version 1.4.0, when a peer returns a FoundRecord, the code verifies the record via dht_verifier.verify(&record.record). On verifier error, handle_dht_get logs and returns early without completing the oneshot used by Network::dht_get, and without cleaning up per-query bookkeeping. Later query progress can hit the "DHT inconsistent state" path and also return without cleanup. Because Network::dht_get awaits the oneshot without a timeout, the caller future can hang indefinitely. This issue has been patched in version 1.4.0.

Antes de la versión 1.4.0, cuando un par devuelve un FoundRecord, el código verifica el registro a través de dht_verifier.verify(&record.record). En caso de error del verificador, handle_dht_get registra y retorna anticipadamente sin completar el oneshot utilizado por Network::dht_get, y sin limpiar la contabilidad por consulta. El progreso posterior de la consulta puede alcanzar la ruta de 'estado inconsistente de DHT' y también retornar sin limpieza. Debido a que Network::dht_get espera el oneshot sin un tiempo de espera, el future del llamador puede colgarse indefinidamente. Este problema ha sido parcheado en la versión 1.4.0."
