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.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20655-1 advisory.

    Update to version 3.20.2.

    Security issued fixed:

    - CVE-2025-55199: specially crafted JSON Schema can lead to out of memory (OOM) termination (bsc#1248093).
    - CVE-2026-35206: specially crafted Chart will have contents extracted to immediate output directory     rather than to       expected output directory suffixed by the Chart's name (bsc#1261938).
