Description Sam Fowler 2018-02-11 21:02:08 EST 
The DPDK vhost-user interface does not check all the requested guest physical range is mapped and contiguous when performing Guest Physical Adresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory.

Statement:

Red Hat OpenStack Platform versions 7 to 9 provided openvswitch-dpdk as a technical preview for customers, it was provided without support and is not intended on being deployed in production.

Red Hat Ceph Storage version 3 provides ceph bundled with DPDK as a technical preview for customers. It was provided without support and is not intended on being deployed in production.

Is the vulnerability fixed upstream? Which version does / will include the fix?
Comment 9 Sandro Bonazzola 2018-04-20 10:54:22 EDT 
Is dpdk-17.11-7.el7 included in RHEL 7.5 affected? I've no access to bug #1555179 (and I don't understand why)

Hi Sandro,

The fix will be delivered on DPDK upstream on Monday around 1pm UTC in:
v16.11.6
v17.11.2
upstream master (will be v18.05).

(In reply to Sandro Bonazzola from comment #9)
> Is dpdk-17.11-7.el7 included in RHEL 7.5 affected?

Yes, all current dpdk versions are affected.

I think this is because it is still under embargo.

Comment 19 Maxime Coquelin 2018-06-15 08:51:12 EDT 
No specific test for this one,
you can run existing vhost-user tests to ensure there is no regression 
introduced. This is what was done for ovs-dpdk.
