In the Linux kernel, the following vulnerability has been resolved:
hsr: hold rcu and dev lock for hsr_get_port_ndev
hsr_get_port_ndev calls hsr_for_each_port, which need to hold rcu lock.
On the other hand, before return the port device, we need to hold the
device reference to avoid UaF in the caller function.
