Helm Charts with Specific JSON Schema Values Can Cause Memory Exhaustion_CVE-2025-55199

{
    "lastseen": "",
    "description": "Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring all Helm charts that are being loaded into Helm do not have any reference of $ref pointing to /dev/zero.",
