[Ksplice-Fedora-20-updates] New updates available via Ksplice (FEDORA-2015-1994)

[Oracle Ksplice]

Synopsis: FEDORA-2015-1994 can now be patched using Ksplice

Systems running Fedora 20 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2015-1994.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 20 install
these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Resource leak in GPIO during sysfs accesses.

Multiple call sites in the GPIO sysfs handling code failed to put
resources on exit.  This could result in failure to remove devices and
memory leaks.


* Userspace memory corruption on page walks.

Incorrect handling of mapped files that had not been written to could
result in reading incorrect data when performing a page walk such as
reading /proc/pid/mem.


* Multiple crashes in Radeon driver during memory copies.

Copies were performed without a valid reservation object resulting in a
kernel crash.  These crashes could be triggered during tests and
benchmarks.


* NULL pointer dereference during hotplug CPU offline.

A race condition when hotplugging a CPU could result in failure to
initialize a percpu thread, causing a NULL pointer dereference when the
CPU was later offlined.
