Is this type of fretboard damage fixable?

This is a Fender Eric Clapton Strat built in 1990 that I bought myself for my 30th birthday as it was the same age.

I played it a bit and this happened. Not sure if it was already damaged and I made it worse or if the old strings caused the damage. There was no noticable damage when I bought it.

Is this type of thing possible to fix? Or will it need a new neck?

Thank you! (First post on Lemmy!)
