DESCRIPTION

* CVE-2016-4578, CVE-2016-4569: Information leak in sound timers.

Missing initialization of stack data structures could result in leaking
the contents of kernel stack memory to user-space.  A local user with
access to the sound device could use this flaw to infer the layout of
kernel memory.


* CVE-2016-4580: Kernel stack information leak in X25 facility negotiation.

Missing initialization of a stack data structure could result in leaking
up to 8 bytes of kernel stack information to a local, unprivileged user.


* CVE-2016-4913: Information leak in ISO9660 filename parsing.

Incorrect handling of NUL termination bytes could result in reading
excessive data from a kernel buffer into user-space.  A local user with
permissions to mount a maliciously crafted filesystem could use this
flaw to leak the contents of sensitive memory.


* CVE-2016-4482: Information leak in USB devfs ioctl.

The USB devfs driver can leak the contents on the kernel stack to
userspace when performing a USBDEVFS_CONNECTINFO operation.


* CVE-2016-4565: Privilege escalation in Infiniband ioctl.

The Infiniband ioctl interface does not correctly validate parameters
from userspace which can allow local users to corrupt kernel memory and
escalate privileges.


* CVE-2016-3134, CVE-2016-4997, CVE-2016-4998: Memory corruption in SO_SET_REPLACE netfilter interface.

The netfilter subsystem does not correctly validate IPT_SO_SET_REPLACE
data from userspace which can allow local users with CAP_NET_ADMIN
privileges to trigger kernel memory corruption and possibly gain
elevated privileges.
