Ubuntu.comUB:CVE-2021-47201CVE-2021-47201
In the Linux kernel, the following vulnerability has been resolved: iavf:
free q_vectors before queues in iavf_disable_vf iavf_free_queues() clears
adapter->num_active_queues, which iavf_free_q_vectors() relies on, so swap
the order of these two function calls in iavf_disable_vf(). This resolves a
panic encountered when the interface is disabled and then later brought up
again after PF communication is restored.
