 in the Linux kernel was too late in checking whether an overwrite of an
 skb data structure may occur, which allowed local users to cause a
 denial of service (system crash) via crafted system calls (bsc#1042892).
- CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux
 kernel allowed remote attackers to cause a denial of service (system
 crash) via a long RPC reply (bsc#1046191).");
