CVE-2025-0750
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 · uneditedA vulnerability was found in CRI-O. A path traversal issue in the log management functions (UnMountPodLogs and LinkContainerLogs) may allow an attacker with permissions to create and delete Pods to unmount arbitrary host paths, leading to node-level denial of service by unmounting critical system directories.
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 confidenceA path traversal vulnerability exists in CRI-O's log management functions (UnMountPodLogs and LinkContainerLogs). Attackers with pod create/delete permissions can exploit this to unmount arbitrary host paths, potentially disrupting critical system directories and causing node-level denial of service.

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.
-
Verify CRI-O is installedRun `crio --version` or check for the crio service with `systemctl list-units | grep crio`Affected if CRI-O is not present, the system uses a different container runtime (containerd, Docker, etc.)
-
Determine CRI-O versionExecute `crio --version` and compare the output to the affected version range provided in the CVE advisoryAffected if The installed version falls within the vulnerable version range and no patch has been applied
-
Identify pod create/delete permission assignmentsReview Kubernetes RBAC policies with `kubectl get roles --all-namespaces` and `kubectl get clusterroles | grep -i pod` to determine which users or service accounts have pod create/delete permissionsAffected if Users or service accounts outside the intended security boundary have pod create/delete permissions
-
Audit recent unmount operations on nodesSearch node logs (journalctl -u kubelet on nodes) for unusual unmount activity or inspect `/var/log/containers/` for unexpected log symlink operationsAffected if Unmount operations target paths outside the expected pod log directory structure (typically /var/log/pods/)
Your environment is affected if CRI-O is running with a vulnerable version AND users with pod create/delete permissions could exploit the path traversal in the UnMountPodLogs/LinkContainerLogs functions.

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 dataApply the CRI-O security patch when available and implement least-privilege principles for pod permissions to limit who can create/delete pods. Consider monitoring for unusual unmount activity.
