Update from 09/19/2019:
After investigating the reported CVE, we figure out that it is a pure hardware issue and there will be no patches for this vulnerability.

We’d like to let you know that we’re aware of the latest NetCat vulnerability report (CVE-2019-11184) for Intel processors. This vulnerability relies on Intel’s Data Direct IO (DDIO) technology, a performance-enhancing feature that allows network devices access to the CPU cache data. The researchers found they could use Intel’s Remote Direct Memory Access feature (RDMA) and statistical analysis of packet data to reveal shared cache data.

Our team is watching this issue and preparing for further upstream developments. We’ll post more information when we have it. Watch this blog or our twitter feed @KernelCare.
