# Execution from dev shm

### Event Information

#### Meaning

* This event indicates that a process is attempting to execute a command from the shared memory (/dev/shm) within a Kubernetes pod.
* It could potentially be a security risk as shared memory is accessible by all containers within the same node, allowing for potential privilege escalation or unauthorized access.
* To investigate further, you can check the specific pod and container where the event occurred using the following kubectl command:` kubectl describe pod <pod_name>`

#### Remediation

* Create a Kubernetes Pod manifest file with a volume mount to a different directory, avoiding the use of /dev/shm:

```yaml theme={null}
apiVersion: v1
kind: Pod
metadata:
  name: remediation-pod
spec:
  containers:
  - name: remediation-container
    image: python
    volumeMounts:
    - mountPath: /mnt
      name: data
  volumes:
  - name: data
    emptyDir: {}
```

* Apply the Pod manifest file to the cluster using kubectl apply:

```bash theme={null}
kubectl apply -f pod_manifest.yaml
```

* Verify that the remediation Pod is running successfully and the container is using the correct volume mount:

```bash theme={null}
kubectl get pods
kubectl describe pod remediation-pod
```
