Is my WiFi under attack?

Hello
I'm new to OpenWRT. I have set up a simple Wireless network with MAC filtering.
By logs it seems like someone is trying to change his MAC and connect.
Am I under attack? Or is it normal.

Below is log fragment:

Not likely. Since MAC addresses are at the whim of the device, current devices (like cell phones) randomize them when looking for wireless nearby to reduce the chances of being easily tracked.

MAC filtering and hidden SSIDs provide virtually no security benefits at this time.
