-Subject: grub-mkconfig: Restore umask for the grub.cfg
-
-The commit ab2e53c8a (grub-mkconfig: Honor a symlink when generating
-configuration by grub-mkconfig) has inadvertently discarded umask for
-creating grub.cfg in the process of running grub-mkconfig. The resulting
-wrong permission (0644) would allow unprivileged users to read GRUB
-configuration file content. This presents a low confidentiality risk
-as grub.cfg may contain non-secured plain-text passwords.
-
-This patch restores the missing umask and sets the creation file mode
-to 0600 preventing unprivileged access.
-
-Fixes: CVE-2021-3981
