CVE-2016-10044 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that a buffer overflow existed in the Bluetooth stack of
the Linux kernel when handling L2CAP configuration responses. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2017-1000251)
It was discovered that the asynchronous I/O (aio) subsystem of the Linux
kernel did not properly set permissions on aio memory mappings in some
situations. An attacker could use this to more easily exploit other
vulnerabilities. (CVE-2016-10044)

CVE-2016-9191 kernel: Local DoS via cgroup offline code
A malicious user who can run an arbitrary image with a non-privileged user
in a Container-as-a-service cloud environment could use the exploit to
deadlock the container nodes to deny the service for other users.
This is confirmed to affect the latest mainline kernel (4.9-rc3) using this
kernel config, http://people.redhat.com/qcai/tmp/config-god-4.9rc2
and as old as v3.17. RHEL 7.3 kernel is not affected.
