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

octeontx2-vf: fix workqueue and netdev race in probe/remove

Initialize the VF workqueue before register_netdev() so ndo_set_rx_mode does not queue work on a NULL workqueue. Unregister the netdev before destroying the workqueue, and add proper probe error cleanup.
