Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Keep the domain reference while processing hotplug We process hotplug events in a workqueue that may run after the domain has been removed by tb_domain_remove(). For example if user unloads the driver while at the same time plugging a device router we may have scheduled tb_handle_hotplug() to run. Avoid possible UAF in this case by taking the domain reference before scheduling the hotplug handler in tb_queue_hotplug().
