CVE-2026-5857

Contiki-NG's MQTT client parsepublishvhdr in os/net/app-layer/mqtt/mqtt.c sets topiclenreceived=1 before checking topiclen against the 64-byte limit, so an over-length topic returns early but leaves the flag set. On the next TCP segment, tcpinput re-invokes the parser with topicreceived==0, and t...

CVE-2026-5857

The CVE-2026-5857 entry documents a bug in Contiki-NG’s MQTT client, where parse_publish_vhdr() sets topic_len_received=1 before validating topic_len against the 64-byte limit.
