CVE-2026-15891

CVE-2026-15891 is a NULL pointer dereference in the Zephyr RTOS MQTT-SN client. The keepalive handler process_ping() in subsys/net/lib/mqtt_sn/mqtt_sn.c discards the return value of SYS_SLIST_PEEK_HEAD_CONTAINER, leaving the gw pointer as NULL. The code then dereferences gw->gw_id and passes i...
