+Subject: [PATCH] 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.
