USN-2527-1: Linux kernel (Trusty HWE) vulnerability

Releases

• Ubuntu 12.04

Packages

• linux-lts-trusty - Linux hardware enablement kernel from Trusty

Details

It was discovered that the Linux kernel's Infiniband subsystem did not
properly sanitize its input parameters while registering memory regions
from userspace. A local user could exploit this flaw to cause a denial of
service (system crash) or to potentially gain administrative privileges.

Update instructions

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

Ubuntu 12.04

• linux-image-3.13.0-46-generic-lpae - 3.13.0-46.79~precise1
• linux-image-3.13.0-46-generic - 3.13.0-46.79~precise1

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