CVE-2026-73863 NanoMQ: Heap-Buffer-Overflow in `nmq_subinfo_decode()` During MQTT v5 SUBSCRIBE Parsing

NanoMQ is an MQTT broker. Prior to 0.24.14, NanoMQ's broker-side MQTT v5 nmqsubinfodecode function in nng/src/sp/protocol/mqtt/mqttparser.c reuses lenofvarint from the outer Properties Length while parsing each SUBSCRIPTIONIDENTIFIER. A remote client can send a SUBSCRIBE packet with a multi-byte...

CVE-2026-73863

NanoMQ, an MQTT broker, contains a heap-buffer-overflow in the broker-side function nmq_subinfo_decode() located in nng/src/sp/protocol/mqtt/mqtt_parser.c. The root cause is an incorrect reuse of the len_of_varint value from the outer Properties Length field when parsing repeated SUBSCRIPTION_IDE...
