/init/main.c issue

[Sticky Chocolate]

I found a issue with some functions in /init/main.c of the linux kernel.
They all involve the problem of the use of strcpy(I found that 3 functions
use strcpy) . I thought maby this could lead to buffer overflow. Im not
completely sure

    strcpy(initcall_command_line, saved_command_line);
    parse_args(initcall_level_names[level],
           initcall_command_line, __start___param,
           __stop___param - __start___param,
           level, level,
           NULL, &repair_env_string);

    for (fn = initcall_levels[level]; fn < initcall_levels[level+1]; fn++)
        do_one_initcall(*fn);

            pr_debug("blacklisting initcall %s\n", str_entry);
            entry = alloc_bootmem(sizeof(*entry));
            entry->buf = alloc_bootmem(strlen(str_entry) + 1);

        }
    } while (str_entry);

    return 0;
