Subject: [PATCH] normal: Remove variables hooks on module unload
|
|
|
|
The normal 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 normal module now but fix the
|
|
issues for completeness.
|
|
|
|
On the occasion replace 0s with NULLs for "pager" variable
|
|
hooks unregister.
|
|
|
|
Fixes: CVE-2025-0622
