In the Linux kernel, the following vulnerability has been resolved:
nfsd: Fix cred ref leak in nfsd_nl_listener_set_doit().
nfsd_nl_listener_set_doit() uses get_current_cred() without put_cred().
As we can see from other callers, svc_xprt_create_from_sa() does not require the extra refcount.
nfsd_nl_listener_set_doit() is always in the process context, sendmsg(), and current->cred does not go away.
Let's use current_cred() in nfsd_nl_listener_set_doit().
