A vulnerability classified as problematic has been found in KubeEdge up to 1.9.3/1.10.1/1.11.0. Affected is some unknown functionality. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. CVE summarizes:

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, a large response received by the viaduct WSClient can cause a DoS from memory exhaustion. The entire body of the response is being read into memory which could allow an attacker to send a request that returns a response with a large body. The consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. The software is affected If users who are authenticated to the edge side connect to `cloudhub` from the edge side through WebSocket protocol. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. There are currently no known workarounds.

The weakness was disclosed 07/12/2022 as GHSA-6wvc-6pww-qr4r. The advisory is available at github.com. This vulnerability is traded as CVE-2022-31080 since 05/18/2022. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.

Upgrading to version 1.9.4, 1.10.2 or 1.11.1 eliminates this vulnerability.

The entries VDB-202865, VDB-202872, VDB-203553 and VDB-203554 are pretty similar.
