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

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a deadlock issue in the Linux kernel's virtio-net driver. It occurs during the probing process when the virtual machine monitor (VMM) sends a VIRTIO_NET_S_ANNOUNCE request while the driver is still initializing. The deadlock happens because the rtnl_lock() function is called recursively in a sequence of function calls, causing the system to hang.


How can this vulnerability impact me? :

This vulnerability can cause a deadlock in the Linux kernel's networking driver, potentially leading to system hangs or unresponsiveness in virtualized environments using virtio-net. This can disrupt network functionality and affect the stability of virtual machines.
