CVE-2017-7645
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.91%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
