  script_tag(name:"insight", value:"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)

Eric Biggers discovered that the key management subsystem in the Linux
kernel did not properly restrict adding a key that already exists but is
uninstantiated. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2017-15299)

It was discovered that a null pointer dereference error existed in the
PowerPC KVM implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash). (CVE-2017-15306)

Eric Biggers discovered a race condition in the key management subsystem of
the Linux kernel around keys in a negative state. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-15951)

Andrey Konovalov discovered that the USB subsystem in the Linux kernel did
not properly validate USB BOS metadata. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2017-16535)

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)");
