Affected: Go: helm.sh/helm/v3

A Helm contributor discovered that a specially crafted JSON Schema within a chart can lead to a stack overflow.

### Impact A JSON Schema file within a chart can be crafted with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow.

### Patches This issue has been resolved in Helm v3.17.3.

### Workarounds Ensure that the JSON Schema within any charts loaded by Helm does not have a large number of nested references. These JSON Schema files are larger than 10 MiB.
