Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ixgbe: Fix NULL pointer dereference in ethtool loopback test<br />
<br />
The ixgbe driver currently generates a NULL pointer dereference when<br />
performing the ethtool loopback test. This is due to the fact that there<br />
isn&#39;t a q_vector associated with the test ring when it is setup as<br />
interrupts are not normally added to the test rings.<br />
<br />
To address this I have added code that will check for a q_vector before<br />
returning a napi_id value. If a q_vector is not present it will return a<br />
value of 0.
