CAI Qian discovered that shared bind mounts in a mount namespace exponentially added entries without restriction to the Linux kernel’s mount table. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-6213)

Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges. (CVE-2016-7097)

Marco Grassi discovered that the driver for Areca RAID Controllers in the Linux kernel did not properly validate control messages. A local attacker could use this to cause a denial of service (system crash) or possibly gain privileges. (CVE-2016-7425)

It was discovered that the KVM implementation for x86/x86_64 in the Linux kernel could dereference a NULL pointer. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the KVM host. (CVE-2016-8630)

Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation in the Linux kernel contained a buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute arbitrary code with administrative privileges.
(CVE-2016-8633)

Marco Grassi discovered that the TCP implementation in the Linux kernel mishandles socket buffer (skb) truncation. A local attacker could use this to cause a denial of service (system crash).
(CVE-2016-8645)

It was discovered that the keyring implementation in the Linux kernel improperly handled crypto registration in conjunction with successful key- type registration. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-9313)

Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation of incoming data. A remote attacker could use this to cause a denial of service (system crash).
(CVE-2016-9555).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
