About vulnerability

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

devlink: fix net namespace reference leak in reload

devlink_nl_reload_doit() calls devlink_netns_get(), which returns a net with a held reference. When the requested namespace differs from the current one and the reload action is not DRIVER_REINIT, the function returns -EOPNOTSUPP without releasing the reference. Add the missing put_net() on this error path.
