This can lead\nto out-of-bounds access and undefined behavior if the buffer does not\nhave sufficient space.\n\nTo address this, a check was added in acpi_nfit_ctl() to ensure that\nbuf is not NULL and that buf_len is less than sizeof(*call_pkg)\nbefore accessing it. This ensures safe access to the members of\ncall_pkg, including the nd_reserved2
