Description OSIDB Bzimport 2026-10-22 21:02:54 UTC 
Memory allocation with excessive size value in the MQTT 3.1.1 compatibility adapter in AWS aws-c-mqtt before 0.16.2 might allow a remote actor to cause a denial of service of the client application.



To remediate this issue, users should upgrade to aws-c-mqtt 0.16.2 or later, or to an AWS Common Runtime or AWS IoT Device SDK release that bundles it.
