[Ksplice-Fedora-27-updates] New Ksplice updates for Fedora 27 (FEDORA-2018-09afae3bb9)

[Oracle Ksplice]

Synopsis: FEDORA-2018-09afae3bb9 can now be patched using Ksplice

Systems running Fedora 27 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2018-09afae3bb9.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Fedora 27
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

* NULL pointer dereference when creating unix domain sockets on CIFS.

Attempting to create a unix domain socket on a mounted CIFS share can
cause a NULL pointer dereference and denial-of-service.


* Memory corruption in Intel i915 graphics driver error path.

In a rare case, the Intel i915 graphics driver would free memory
directly that was still in use in a cache, causing corruption or a
denial-of-service.


* Use-after-free when deleting net namespaces.

When tearing down a net namespace, hwsim wireless interfaces are deleted
asynchronously. The namespace destruction can proceed simultaneously,
resulting in a denial-of-service when the hwsim interfaces are deleted.


* NULL-pointer dereference when debugging xhci device.

In rare cases, disconnecting an xhci device while debugging can cause
the device to unregister itself twice, causing a NULL pointer
dereference and denial-of-service.
