CVE-2017-14106

Priority
Description
The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before
4.12 allows local users to cause a denial of service (__tcp_select_window
divide-by-zero error and system crash) by triggering a disconnect within a
certain tcp_recvmsg code path.
Ubuntu-Description
Andrey Konovalov discovered that a divide-by-zero error existed in the TCP
stack implementation in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash).
