host OS memory corruption via rtas_args.nargs (bsc#1188838).
CVE-2021-28688: The fix for XSA-365 includes initialization of pointers
such that subsequent cleanup code wouldn't use uninitialized or stale
values. This initialization went too far and may under certain
conditions also overwrite pointers which are in need of cleaning up.
