Summary
[none]
Details

In the Linux kernel, the following vulnerability has been resolved:

iavf: free qvectors before queues in iavfdisable_vf

iavffreequeues() clears adapter->numactivequeues, which iavffreeqvectors() relies on, so swap the order of these two function calls in iavfdisable_vf(). This resolves a panic encountered when the interface is disabled and then later brought up again after PF communication is restored.
