NewCVE-2025-55199 (opens in a new tab)How to fix?
There is no fixed version for helm.sh/helm/pkg/chartutil.
Overview
helm.sh/helm/pkg/chartutil is a package that contains tools for working with charts.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the processing of JSON Schema files containing $ref fields that point to device files such as /dev/zero. An attacker can cause memory exhaustion and termination of the process by supplying a malicious chart with specially crafted schema references.
Workaround
This vulnerability can be mitigated by ensuring that all loaded charts do not contain $ref fields pointing to /dev/zero.
