Vulnerability details
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to allocation of resources without limits or throttling in validate_partitions when processing partition count values in super-stream partition requests. A remote privileged user can submit a request with an excessively large partition count to cause a denial of service.
