[nwf]

network-stack/include/mqtt.h

Lines 149 to 151 in d7f260d

	* this function. If the caller frees them during the execution of this
	* function, the publish may leak application data to the broker through the
	* topic and payload.

That sounds like a UAF/UAR issue that shouldn't be an information leak on CHERIoT? Do I misunderstand?
