CVE-2026-104618 SUSE CVE debrief

The `sdbootutil` script creates a world-readable debug log in `/var/log/sdbootutil.log`, allowing arbitrary low-privileged users to extract secrets from it. This vulnerability affects systems using the `sdbootutil` script, with a medium severity impact. System administrators and security teams should review and correct file permissions to prevent unauthorized access to sensitive information. The CVE record and NVD entry provide limited information about the vulnerability, and further investigation is required to determine the affected systems and potential impact. The `sdbootutil` script's debug log is created with world-readable permissions, which can be exploited by low-privilege

Who should care

System administrators and security teams responsible for managing and securing systems using the `sdbootutil` script should review and correct file permissions to prevent unauthorized access to sensitive information.

Why it matters

The CVE-2026-104618 vulnerability in the `sdbootutil` script allows low-privileged users to extract secrets from a world-readable debug log. System administrators and security teams should review and correct file permissions to prevent unauthorized access to sensitive information. The impact of this vulnerability is medium, and the priority for remediation is medium.

  • Low-privileged users can access sensitive information from the debug log.
  • System administrators need to review and correct file permissions to prevent unauthorized access.

Technical summary

The `sdbootutil` script creates a world-readable debug log in `/var/log/sdbootutil.log`, allowing arbitrary low-privileged users to extract secrets from it. The log file is created with world-readable permissions, which means that low-privileged users can access sensitive information from the debug log. System administrators and security teams should review and correct file permissions to prevent unauthorized access to sensitive information. The vulnerability has a medium severity impact, and the priority for remediation is medium.

Defensive priority

Medium priority for system administrators to review and correct file permissions.

Recommended defensive actions

  • Review and correct file permissions for the `/var/log/sdbootutil.log` file.
  • Restrict access to the debug log file to authorized personnel only.
  • Monitor system logs for potential exploitation attempts.

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability. Further investigation is required to determine the affected systems and potential impact.
