[Ksplice-Fedora-28-updates] New Ksplice updates for Fedora 28 (FEDORA-2018-cfc5245d6e)

[Oracle Ksplice]

Synopsis: FEDORA-2018-cfc5245d6e can now be patched using Ksplice

Systems running Fedora 28 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2018-cfc5245d6e.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Fedora 28
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

* Improved fix for Spectre v1: Bounds-check bypass in asynchronous I/O subsystem.

A missing sanitization of array index after bounds check in asynchronous
I/O subsystem could lead to an information leak. A local attacker
could use this flaw to leak information about running system.


* Checksum validation failure in AQtion ethernet controller.

A logic error during packet checksum verification in the AQtion
ethernet controller driver can lead to packets with bad checksums being
treated as valid packets.  This could allow a remote attacker to trigger
unexpected behavior in the driver.


* Denial-of-service when closing an AF_VSOCK socket.

A memory leak when closing a socket from the VSOCK address family could
allow an unprivileged process to exhaust kernel memory and cause a
denial-of-service.


* Denial-of-service when sending NVMe packets over RDMA.

A use-after-free bug in the error path when sending NVMe packet over
RDMA fails could lead to uninitialized memory access and cause a
denial-of-service.
