CVE-2026-72109

In the Linux kernel, the following vulnerability has been resolved:

net: sparx5: unregister blocking notifier on init failure

sparx5_register_notifier_blocks() registers the switchdev blocking

notifier before allocating the ordered workqueue. If the workqueue

allocation fails, the error path unregisters the switchdev and netdevice

notifiers, but leaves the blocking notifier registered.

Add a separate error label for the workqueue allocation failure path and

unregister the switchdev blocking notifier there.
