linux vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel

Details:

Pengfei Wang discovered that the Turtle Beach MultiSound audio device
driver in the Linux kernel contained race conditions when fetching from the
ring-buffer, leading to an out-of-bounds access. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-9986)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- Ethernet bonding driver;
- PCI subsystem;
- SCSI subsystem;
- Tracing infrastructure;
- B.A.T.M.A.N. meshing protocol;
- IUCV driver;
(CVE-2022-49114, CVE-2023-52784, CVE-2024-53194, CVE-2024-53210,
CVE-2024-56763, CVE-2026-31657, CVE-2026-43456)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS
linux-image-3.13.0-220-generic 3.13.0-220.271
Available with Ubuntu Pro
linux-image-3.13.0-220-lowlatency 3.13.0-220.271
Available with Ubuntu Pro
linux-image-generic 3.13.0.220.230
Available with Ubuntu Pro
linux-image-generic-lts-trusty 3.13.0.220.230
Available with Ubuntu Pro
linux-image-lowlatency 3.13.0.220.230
Available with Ubuntu Pro
linux-image-server 3.13.0.220.230
Available with Ubuntu Pro
linux-image-virtual 3.13.0.220.230
Available with Ubuntu Pro

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
