Subject: [PATCH 05/20] fs/hfsplus: Set a grub_errno if mount fails
|
|
|
|
It was possible for mount to fail but not set grub_errno. This led to
|
|
a possible double decrement of the module reference count if the NULL
|
|
page was mapped.
|
|
|
|
Fixing in general as a similar bug was fixed in commit 61b13c187
|
|
(fs/hfsplus: Set grub_errno to prevent NULL pointer access) and there
|
|
are likely more variants around.
|
|
|
|
Fixes: CVE-2024-45783
