CVE-2024-39743
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM MQ Operator 3.2.2 and IBM MQ Operator 2.0.24 IBM MQ Container Developer Edition is vulnerable to denial of service caused by incorrect memory de-allocation. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. IBM X-Force ID: 297172.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIBM MQ Operator versions 3.2.2 and 2.0.24 contain a memory management flaw where incorrect memory de-allocation allows remote attackers to trigger excessive memory consumption, leading to denial of service conditions.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.
NVD · CPE data>= 2.0.0, < 2.0.24>= 2.2.0, <= 2.2.2>= 2.3.0, <= 2.3.3>= 2.4.0, <= 2.4.8>= 3.1.0, <= 3.1.3>= 3.2.0, < 3.2.2= 3.0.0= 3.0.1CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if IBM MQ Operator is installedRun 'kubectl get pods -A | grep -i mq' or 'kubectl get crd | grep -i queuemanager' to check for IBM MQ Operator deployments in the clusterAffected if No IBM MQ Operator pods or custom resources are found in the cluster, then the environment is not affected
-
Determine the installed IBM MQ Operator versionRun 'kubectl get deployment -A | grep -i mq' to find the operator deployment, then use 'kubectl get deployment <operator-deployment-name> -n <namespace> -o jsonpath={.spec.template.spec.containers[0].image}' to get the container image, or check the operator CSV: 'kubectl get csv -A | grep ibm-mq' and check the version columnAffected if The installed version falls within any of these ranges: >= 2.0.0 and < 2.0.24, >= 2.2.0 and <= 2.2.2, >= 2.3.0 and <= 2.3.3, >= 2.4.0 and <= 2.4.8, >= 3.1.0 and <= 3.1.3, >= 3.2.0 and < 3.2.2, equals 3.0.0, or equals 3.0.1
-
Check if the operator is exposed to network trafficReview Kubernetes network policies and service definitions: 'kubectl get svc -A | grep -i mq' and 'kubectl get networkpolicy -A', then inspect whether the operator API or queue manager listeners are accessible from outside the cluster or from untrusted network sourcesAffected if The MQ Operator or its queue managers have network services exposed externally (LoadBalancer, NodePort, or ingress) without proper network segmentation, increasing the likelihood of remote exploitation
The environment is affected if IBM MQ Operator is installed and the installed version matches any of the vulnerable version ranges, particularly if the operator or its managed queue managers are network-accessible to remote attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data2.0.243.2.2
Apply vendor patches when available; otherwise, implement Kubernetes resource quotas and limits on MQ operator pods to constrain memory usage and mitigate exhaustion attacks.
