Subject: Nethammer and kernel network drivers

Hello. I wanted to get your attention about a new, more serious
reincarnation of rowhammer called nethammer that doesn't need to execut
any code on the system like in the past nor does it leave a trace.

The summary of the paper is that rowhammer can be
remotely triggered by feeding susceptible* network driver crafted
traffic. This attack can do all kinds of nasty things such as modifying
SSL certs on the victim system.

* Susceptible drivers are those relying on Intel CAT, uncached memory or
the clflush instruction.

In absence of hardware mitigations, please identify and disable/fix
susceptible network drivers to avoid this type of attack. Thanks.
