Affected: Linux Kernel Organization, Inc. Linux Kernel

A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.

Affected: Ubuntu:16.04:LTS: linux, Ubuntu:16.04:LTS: linux-aws, Ubuntu:16.04:LTS: linux-kvm

Jann Horn and Ken Johnson discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via a sidechannel attack. This flaw is known as Spectre Variant 4. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2018-3639)

Tuba Yavuz discovered that a double-free error existed in the USBTV007 driver of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-17975)

It was discovered that a race condition existed in the F2FS implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18193)

It was discovered that a buffer overflow existed in the Hisilicon HNS Ethernet Device driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-18222)

It was discovered that the netfilter subsystem in the Linux kernel did not validate that rules containing jumps contained user-defined chains. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-1065)

It was discovered that the netfilter subsystem of the Linux kernel did not properly validate ebtables offsets. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-1068)
