Subject: [PATCH 10/20] commands/extcmd: Missing check for failed allocation
|
|
|
|
The grub_extcmd_dispatcher() calls grub_arg_list_alloc() to allocate
|
|
a grub_arg_list struct but it does not verify the allocation was successful.
|
|
In case of failed allocation the NULL state pointer can be accessed in
|
|
parse_option() through grub_arg_parse() which may lead to a security issue.
|
|
|
|
Fixes: CVE-2024-45775
