Created attachment 231295 [details] A simple fix for this bug In sys/rpc/svc_dg.c file, the return value of svc_xprt_alloc() is assigned to xprt and there is a dereference of it right after that, which would lead to NULL pointer dereference on failure of allocation. Fix this bug by adding a NULL check of xprt. This bug is found by static analyzer, please advise.
