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.

- GHSA-9h84-qmv7-982pHelm Charts with Specific JSON Schema Values Can Cause Memory Exhaustion2025-08-14ghsa · osvUS
A Helm contributor discovered that it was 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. ### Impact A malicious chart can point `$ref` in _values.schema.json_ to a device (e.g. `/dev/*`) or other problem file which could cause Helm to use all available memory and have an out of memory (OOM) termination. ### Patches This issue has been resolved in Helm v3.18.5. ### Workarounds Make sure that all Helm charts that are being loaded into Helm doesn't have any reference of `$ref` pointing to `/dev/zero`. ### References Helm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document. ### Credits Disclosed by Jakub Ciolek at AlphaSense.
