CVE-2025-0750 — Cri-o: cri-o path traversal in log handling functions allows arbitrary unmounting
A 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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.3% (30-day exploitation probability)+3
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Red Hat Red Hat OpenShift Container Platform 4, Red Hat Red Hat OpenShift Container Platform 4.17, Go Github.com/cri-o/cri-o).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?
CVE-2025-0750 is "Cri-o: cri-o path traversal in log handling functions allows arbitrary unmounting", rated Medium. It affects Red Hat OpenShift Container Platform 4 (Red Hat); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.6 describes technical severity. EPSS 0.27% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
