Summary

The OpenKruise kruise-manager component, which runs as part of the OpenKruise Kubernetes extension suite, is affected. When its pprof profiling endpoint is enabled, it is exposed without authentication on all network interfaces, so any pod with RBAC access can trigger a denial-of-service condition.

Read the original description

OpenKruise kruise-manager exposes an unauthenticated ppof endpoint when enabled, opening it on 0.0.0.0:8090, which can enable a DoS attack triggerable by any RBAC pod.

What to do

  • Upgrade to a fixed version: v1.9.2.

  • Workaround: Add --enable-pprof=false to the kruise-manager container args

FAQ

Questions about CVE-2026-120656

What does this mean?

The pprof profiling endpoints in kruise-manager were enabled by default and bound to all interfaces. Repeated requests to them can exhaust the manager's memory until it goes NotReady, and because the admission webhooks fail closed, pod creation can be blocked cluster-wide. The endpoints also expose the manager's goroutine stacks and heap profiles.Source: github.com, github.com

Am I affected, and how do I check?

The advisory says kruise-manager up to and including v1.9.1 is affected, and the fix is in v1.9.2. To check a deployment, look at the kruise-manager container args for --enable-pprof; the flag defaults to true when it is not set.Source: github.com, github.com

What should I do about it?

Upgrade kruise-manager to v1.9.2 or later. If an upgrade is not possible yet, add --enable-pprof=false to the kruise-manager container args.Source: github.com, github.com

Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
