K62178133 : Linux kernel vulnerability CVE-2017-14106

Security Advisory 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. (CVE-2017-14106)

Impact

An attacker local to the system may be able to cause a kernel panic, resulting in a local denial-of-service (DoS) when the vulnerability is exploited.
