In the Linux kernel, the following vulnerability has been resolved: iavf: Fix out-of-bounds when setting channels on remove If we set channels greater during iavf_remove(), and waiting reset done would be timeout, then returned with error but changed num_active_queues directly, that will lead to OOB like the following logs. Because the num_active_queues is greater than tx/rx_rings[] allocated actually.
