Description

A NULL pointer dereference flaw was found in KubeVirt. This flaw allows an attacker who has access to a virtual machine guest on a node with DownwardMetrics enabled to cause a denial of service by issuing a high number of calls to vm-dump-metrics --virtio and then deleting the virtual machine.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for kubevirt.io/kubevirt, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of kubevirt.io/kubevirt for CVE-2024-31420. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
