Subject: [PATCH 13/20] gettext: Remove variables hooks on module unload
|
|
|
|
The gettext module does not entirely cleanup after itself in
|
|
its GRUB_MOD_FINI() leaving a few variables hooks in place.
|
|
It is not possible to unload gettext module because normal
|
|
module depends on it. Though fix the issues for completeness.
|
|
|
|
Fixes: CVE-2025-0622
