[USN-3364-3] Linux kernel (AWS, GKE) vulnerabilities

Severity Medium

Affected Packages 3

CVEs 6

Several security issues were fixed in the Linux kernel.

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)

It was discovered that the Linux kernel did not properly restrict access to
/proc/iomem. A local attacker could use this to expose sensitive
information. (CVE-2015-8944)

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)

Jann Horn discovered that bpf in Linux kernel does not restrict the output
of the print_bpf_insn function. A local attacker could use this to obtain
sensitive address information. (CVE-2017-9150)

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)
