DESCRIPTION

* CVE-2013-3223: Kernel stack information leak in amateur radio drivers.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3224: Kernel stack information leak in Bluetooth sockets.

Receiving messages from a bluetooth socket whilst the socket is
simultaneously being shut down could leak kernel stack bytes to
userspace allowing a local user to gain information about the running
kernel.


* CVE-2013-3235: Kernel stack information leak in TIPC protocol.

Missing initialization could allow a local user to leak stack
information when receiving messages on a Transparent Inter Process
Communication (TIPC) socket.


* CVE-2013-3234: Kernel stack information leak in ROSE protocol.

Missing initialization could allow a local user to leak kernel stack
information when receiving from a ROSE socket.


* CVE-2013-3225: Kernel stack information leak in Bluetooth rfcomm.

Missing data clearing operations could allow a local user to leak kernel
stack memory to userspace.


* CVE-2013-3222: Kernel stack information leak in ATM sockets.

Missing data clearing operations could allow an unprivileged user to
leak kernel stack memory to userspace.


* Kernel deadlock in Xen pv-spinlocks.

A race condition can lead to a deadlock where a CPU gets stuck
waiting forever for a lock.


* CVE-2013-1798: Information leak in KVM APIC driver.

The KVM paravirtualized APIC driver does not correctly validate arguments
from the guest virtual machine when querying the APIC device allowing a
malicious guest virtual machine read kernel memory from the host.


* CVE-2013-3231: Kernel stack information leak in LLC sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3232: Kernel stack information leak in amateur radio NET/ROM driver.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages from a NET/ROM socket.


* CVE-2013-3228: Kernel stack information leak in IRDA sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3229: Kernel stack information leak in IUCV sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages from an iUCV socket.
