1. A method for wireless communication at a device, comprising:
receiving a set of vehicle-to-everything (V2X) messages during a time window for detection of fuzzing attacks, each V2X message of the set of V2X messages comprising a set of information element fields associated with V2X operations of a second device in accordance with the device operating within a V2X communications system;
determining a change to one or more information element fields of the set of information element fields in multiple V2X messages of the set of V2X messages received in the time window based at least in part on a comparison of a respective value associated with each of the one or more information element fields to a respective expected value associated with each of the one or more information element fields, each V2X message of the multiple V2X messages comprising a same identifier associated with the second device and comprising a respective basic safety message associated with the V2X operations of the second device;
detecting a fuzzing attack associated with the multiple V2X messages of the set of V2X messages received in the time window based at least in part on determining the change; and
transmitting, to a network entity, a single report indicating the fuzzing attack and including evidence of the fuzzing attack aggregated from the multiple V2X messages based at least in part on determining the change and based at least in part on the multiple V2X messages comprising the same identifier.
