CVE-2026-92768 Red Hat CVE debrief

Who should care

Local system administrators and security teams, especially in multi-user environments where process arguments may not be restricted, should assess exposure and take necessary actions to protect VM credentials.

Why it matters

CVE-2026-92768 allows local attackers to expose sensitive VM credentials by inspecting process command-line arguments. Defenders should verify and restrict process argument visibility, especially in multi-user environments, and update cockpit-machines to the latest version.

• Information disclosure due to sensitive VM credentials exposure
• Potential compromise of VM access
• Need for verification of process argument restrictions
• Priority for updating cockpit-machines to the latest version

Technical summary

The cockpit-machines component passes password values directly on the command line, making them visible to other local users on systems where process arguments are not restricted. This allows local attackers to expose sensitive Virtual Machine (VM) credentials, including plaintext passwords, by inspecting process command-line arguments during VM creation or installation. Affected product deployments should be reviewed for exposure, and owners should be assigned for follow-up. The official advisory or CVE record should be consulted to validate affected scope, severity, and vendor guidance.

Defensive priority

Medium priority for local system administrators and security teams to verify and restrict process argument visibility, especially in multi-user environments.

Recommended defensive actions

• Verify and restrict process argument visibility in multi-user environments
• Review and update cockpit-machines to the latest version
• Implement additional security measures to protect VM credentials
• 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
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
