Details

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

net/mlx5: Fix IPsec cleanup over MPV device

When we do mlx5e_detach_netdev() we eventually disable blocking events notifier, among those events are IPsec MPV events from IB to core.

So before disabling those blocking events, make sure to also unregister the devcom device and mark all this device operations as complete, in order to prevent the other device from using invalid netdev during future devcom events which could cause the trace below.
