[Oracle Ksplice]

Synopsis: FEDORA-2016-3daf782dfa can now be patched using Ksplice

Systems running Fedora 22 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2016-3daf782dfa.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 22 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

* Kernel panic when initializing Realtek 8xxx WiFi device.

Invalid locking when resetting the transfer/receive ring-buffers for
Realtek 8xxx devices can trigger an assertion trigger a kernel panic.


* Denial of service with corrupt orphan list on ext4 filesystem.

The kernel ext4 filesystem driver does not correctly corrupt orphan
inode lists which can trigger an infinite loop and kernel deadlock.


* Kernel panic when adding orphaned inodes on ext4 filesystem.

A logic error when adding orphaned inodes on ext4 filesystems can
trigger memory corruption and kernel panic.


* Use after free in when failing xfs inode writeback.

Incorrect locking when flushing inodes on an xfs filesystem can trigger
a use after free and kernel panic.


* Kernel information leak in TIPC compatibility dump ioctl.

The kernel TIPC driver does not correctly initialize kernel memory which
is copied to userspace leading to the contents of kernel memory being
leaked to userspace.


* Kernel information leak when sending RDS messages.

The kernel RDS driver does not correctly initialize kernel memory when
creating RDS messages which can lead to the contents of kernel memory
being leaked to userspace.


* Use after free when loading Atheros 10k WiFi driver.

A race condition between initializing an Atheros 10k device and
receiving frames can trigger a use after free and kernel panic.


* Kernel panic when resuming Xen VM from suspend.

A logic error when resuming a Xen VM from suspend can trigger an
assertion failure and kernel panic when moving IRQs that have been
disabled.
