[Ksplice-Fedora-19-updates] New updates available via Ksplice (FEDORA-2013-13964)

[Jamie Iles]

Synopsis: FEDORA-2013-13964 can now be patched using Ksplice

Systems running Fedora 19 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2013-13964.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 19 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

* Data loss in filesystems due to missing writeback.

Incorrect handling of periodic writeback could cause filesystems to fail
to write data back to disk leading to corruption in the case of a crash
or power failure.


* Kernel crash in FUSE filesystem readdir().

Missing reference counting could cause the kernel to leak filesystem
objects resulting in a kernel BUG() when unmounting a FUSE filesystem.


* NULL pointer dereference in bcache closures.

Invalid reference counting could result in a NULL pointer dereference
when performing closure destructors in the bcache subsystem.


* NULL pointer dereference in LSI MPT Fusion SAS 3.0 probing.

With some enclosures where LUN 0 is created after the other LUN's or not
at all, incorrect initialization could lead to a NULL pointer
dereference in the discovery process.


* Memory leak in LSI Megaraid controller management firmware interface.

Incorrect handling of scatter-gather lists with 0 sized entries could
result in a memory leak of DMA coherent memory.


* Filesystem corruption on ext4 truncation.

Missing error handling could result in filesystem corruption when
removing extents during truncation.


* Use-after-free in DVB ring buffer.

Incorrect use of a lockless ring buffer could result in accessing
invalid data triggering a use-after-free and kernel crash.


* Use-after-free in NFS lock daemon lock retry mechanism.

Missing locking could result in a race condition with the retry list
allowing the kernel to use a freed item resulting in a kernel crash.


* Kernel crash during simultaneous iee80211 channel switch and removal.

Removing a WiFi device during a channel switch could result in a NULL
pointer dereference and kernel crash.
