CVE-2026-104795 Red Hat CVE debrief

Who should care

Administrators and security teams managing containerized environments, particularly those using Red Hat OpenShift Container Platform 4, should be aware of this vulnerability. They should review and restrict privileged DaemonSet configurations, monitor container processes for suspicious activity, and implement additional security controls to mitigate potential risks. Security teams should prioritize vulnerability management and ensure that proper security措施

Why it matters

CVE-2026-104795 allows container escape via privileged binary execution in Red Hat OpenShift Container Platform 4, requiring high priority attention and additional security controls.

• Potential container escape and privilege escalation
• Increased risk of unauthorized access and data breaches
• Need for enhanced monitoring and security controls

Technical summary

The insights-runtime-extractor runs as a privileged DaemonSet, scanning container processes for runtime fingerprinting. A vulnerability allows container escape via privileged binary execution. The extractor's use of hostPID and execution of workload-controlled binaries with elevated privileges enables an attacker to execute arbitrary code with elevated privileges. This issue requires immediate attention, particularly for Red Hat OpenShift Container Platform 4 deployments. Affected administrators should assess their exposure and implement compensating controls if necessary.

Defensive priority

High priority for containerized environments using Red Hat OpenShift Container Platform 4

Recommended defensive actions

• Review and restrict privileged DaemonSet configurations
• Monitor container processes for suspicious activity
• Implement additional security controls for containerized environments
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
