Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> virtio-net: fix recursived rtnl_lock() during probe()<br /> <br /> The deadlock appears in a stack trace like:<br /> <br /> virtnet_probe()<br /> rtnl_lock()<br /> virtio_config_changed_work()<br /> netdev_notify_peers()<br /> rtnl_lock()<br /> <br /> It happens if the VMM sends a VIRTIO_NET_S_ANNOUNCE request while the<br /> virtio-net driver is still probing.<br /> <br /> The config_work in probe() will get scheduled until virtnet_open() enables<br /> the config change notification via virtio_config_driver_enable().
