Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> hv_netvsc: Register VF in netvsc_probe if NET_DEVICE_REGISTER missed<br /> <br /> If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER<br /> handler cannot perform VF register successfully as the register call<br /> is received before netvsc_probe is finished. This is because we<br /> register register_netdevice_notifier() very early( even before<br /> vmbus_driver_register()).<br /> To fix this, we try to register each such matching VF( if it is visible<br /> as a netdevice) at the end of netvsc_probe.
