Detail

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

net/mlx5e: Fix null deref accessing lag dev

It could be the lag dev is null so stop processing the event. In bond_enslave() the active/backup slave being set before setting the upper dev so first event is without an upper dev. After setting the upper dev with bond_master_upper_dev_link() there is a second event and in that event we have an upper dev.
