have been exploited by unprivileged users to gain root access
- 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).
- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
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).
