Descriptions
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().
