Comment 2 Vladis Dronov 2016-01-04 11:31:55 EST
a root access is needed on a virtual machines with SRIOV network card's VF allocated to disturb communications of other VMs on the same host which use the same SRIOV network card.

the problem i see here is that every driver for SRIOV cards should be checked/modified, to properly close this, not a kernel code. there are fixes for intel and broadcom cards (see http://seclists.org/oss-sec/2015/q4/425), but no CVE assigned since Dec 3 2015. looks more like a security hardening than security issue.
Comment 3 Josh Boyer 2016-01-05 15:25:46 EST
I agree with Vladis' assessment.  The fixes for this will come in piecemeal through individual drivers or in some cases through device firmware updates.  After discussing with the rest of the kernel team, we are closing this as upstream.
