USN-2529-1: Linux kernel (Utopic HWE) vulnerability

Releases

• Ubuntu 14.04 ESM

Packages

• linux-lts-utopic - Linux hardware enablement kernel from Utopic

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.

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

Ubuntu 14.04

• linux-image-3.16.0-31-generic - 3.16.0-31.43~14.04.1
