"It was discovered that the Linux kernel did not properly initialize a
Wake- on-Lan data structure. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2014-9900)

Alexander Potapenko discovered a race condition in the Advanced Linux
Sound Architecture (ALSA) subsystem in the Linux kernel. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-1000380)

Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the
Linux kernel did not properly validate some ioctl arguments. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-7346)

Murray McAllister discovered that the DRM driver for VMware Virtual
GPUs in the Linux kernel did not properly initialize memory. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-9605).

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."
