Details
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:

InfiniBand drivers;
Netfilter;
Network traffic control

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