In the Linux kernel, the following vulnerability has been resolved:
macvlan: fix possible UAF in macvlan_forward_source()
Add RCU protection on (struct macvlan_source_entry)->vlan.
Whenever macvlan_hash_del_source() is called, we must clear entry->vlan pointer before RCU grace period starts.
This allows macvlan_forward_source() to skip over entries queued for freeing.
Note that macvlan_dev are already RCU protected, as they are embedded in a standard netdev (netdev_priv(ndev)).
