Kubernetes Nil pointer dereference in KCM after v1 HPA patch request

CVE-2024-0793GHSA-h7wq-jj8r-qm7p

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (k8s.io/kubernetes 1.27.0-alpha.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

A flaw was found in kube-controller-manager. This issue occurs when the initial application of a HPA config YAML lacking a .spec.behavior.scaleUp block causes a denial of service due to KCM pods going into restart churn.

# Patch Next advisory brief: CVE-2024-0793

Advisory: Kubernetes Nil pointer dereference in KCM after v1 HPA patch request
IDs: CVE-2024-0793, GHSA-h7wq-jj8r-qm7p
Record: https://patchnext.com/advisories/cve-2024-0793 (revision 1, source checked 26 Oct 2026, 15:08 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: k8s.io/kubernetes 1.27.0-alpha.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go k8s.io/kubernetes: affected < 1.27.0-alpha.1; fixed in 1.27.0-alpha.1

## Suggested inspection (read-only)
- Go k8s.io/kubernetes: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on k8s.io/kubernetes.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-h7wq-jj8r-qm7p (GitHub-reviewed advisory GHSA-h7wq-jj8r-qm7p lists affected ranges: Go k8s.io/kubernetes >=0 <1.27.0-alpha.1)

Commands are suggestions: review each one before running it.
