 What does it mean "current source"? Please be specific which exactly

kernel version is affected, which commit introduced it.

Then the risk is quite low, right? SPI busses are not user hot-pluggable

except some development boards (so again a real niche). Basically it's
impact is negligible

Agreed.

What does it mean "remote device"? NFC? NFC tag does not talk over SPI...

I was wondering maybe the tag is the source for the content that actually
overflows the kernel buffer,
In which case it changes the picture a bit.

The buffer is used for SPI transfer, so the NFC tag - except that it
works with that device - is rather long shot.
