Details

In the Linux kernel, the following vulnerability has been resolved: bonding: 3ad: implement proper RCU rules for port->aggregator syzbot found a data-race in bond_3ad_get_active_agg_info / bond_3ad_state_machine_handler [1] which hints at lack of proper RCU implementation. Add __rcu qualifier to port->aggregator, and add proper RCU API.
