Yue Cao et al discovered a flaw in the TCP implementation's handling of
challenge acks in the Linux kernel. A remote attacker could use this to
cause a denial of service (reset connection) or inject content into an TCP
stream. (CVE-2016-5696)

It was discovered that a heap based buffer overflow existed in the USB HID
driver in the Linux kernel. A local attacker could use this cause a denial
of service (system crash) or possibly execute arbitrary code.
