AnalysisAIv1 – Sep 15, 2026

A path-handling flaw in the containers/storage Go library lets a crafted tar archive containing a malicious whiteout entry (for example 'victim/.wh.') cause UnpackLayer, ApplyLayer, or ApplyUncompressedLayer to replace the extraction destination directory with an arbitrary file. Systems that unpack container image layers with this library — notably Red Hat Enterprise Linux 10, Red Hat Ansible Automation Platform 2, OpenShift Container Platform 4, Quay 3, OpenShift Virtualization, Dev Spaces, and Red Hat Hardened Images — are in scope. Exploitation requires the operator or process to unpack an attacker-supplied archive, and the integrity impact is confined to the local extraction target; no public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, consistent with the modest CVSS 3.1 base score of 4.4.

What every action level means
Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.
Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.
This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.
This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.
Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
