How to fix?

Upgrade SLES:16.0.0 kernel-docs-html to version 6.12.0-160000.26.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs-html package and not the kernel-docs-html package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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().
