We apologize for the inconvenience.

Original advisory details:

 Mohamed Ghannam discovered that a use-after-free vulnerability existed in
 the Netlink subsystem (XFRM) in the Linux kernel. A local attacker could
 use this to cause a denial of service (system crash) or possibly execute
 arbitrary code. (CVE-2017-16939)

 It was discovered that the Linux kernel did not properly handle copy-on-
 write of transparent huge pages. A local attacker could use this to cause a
 denial of service (application crashes) or possibly gain administrative
 privileges. (CVE-2017-1000405)

 Fan Wu, Haoran Qiu, and Shixiong Zhao discovered that the associative array
 implementation in the Linux kernel sometimes did not properly handle adding
 a new entry. A local attacker could use this to cause a denial of service
 (system crash). (CVE-2017-12193)

 Andrey Konovalov discovered an out-of-bounds read in the GTCO digitizer USB
 driver for the Linux kernel. A physically proximate attacker could use this
 to cause a denial of service (system crash) or possibly execute arbitrary
 code. (CVE-2017-16643)");
