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...

CVE-2026-15891 NULL pointer dereference in Zephyr MQTT-SN client when removing a non-responsive gateway

The MQTT-SN client keepalive handler processping in subsys/net/lib/mqttsn/mqttsn.c removes the gateway record after PINGREQ retries are exhausted. It invoked SYSSLISTPEEKHEADCONTAINER&client-gateways, gw, next but discarded the result. That macro is a pure expression that does not assign to gw, s...
