Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

It was discovered that the Option USB High Speed Mobile device driver in
the Linux kernel did not properly handle error conditions. A physically
proximate attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2021-37159)

A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystem:

Update instructions

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

Learn more about how to get the fixes.

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.

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

Ubuntu Release Package Version
14.04 trusty linux-image-3.13.0-199-generic –  3.13.0-199.250  
linux-image-3.13.0-199-lowlatency –  3.13.0-199.250  
linux-image-generic –  3.13.0.199.209  
linux-image-generic-lts-trusty –  3.13.0.199.209  
linux-image-lowlatency –  3.13.0.199.209  
linux-image-server –  3.13.0.199.209  
linux-image-virtual –  3.13.0.199.209
