CVE-2026-104618 [MEDIUM] – On request the `sdbootutil` script creates a world-readable debug log in /var/log/sdbootut

On request the `sdbootutil` script creates a world-readable debug log in /var/log/sdbootutil.log. The log file is created world-readable, however, which means that arbitrary low-privileged users in the system will be able to extract secrets from it.
