cause a denial of service (system crash). (CVE-2015-7550)
Guo Yong Gang discovered that the Linux kernel networking implementation did
not validate protocol identifiers for certain protocol families, A local

possibly gain administrative privileges. (CVE-2015-8543)

did not verify an address length when setting up a socket. A local attacker
could use this to craft an application that exposed sensitive information
from kernel memory. (CVE-2015-8569)

kernel did not properly validate the socket address length for Synchronous
Connection-Oriented (SCO) sockets. A local attacker could use this to
expose sensitive information. (CVE-2015-8575)

implementation did not handle initial zero length segments properly. A
local attacker could use this to cause a denial of service (unkillable
task). (CVE-2015-8785)");
