Nothing much. Once particle board gets wet and dries it crumbles. Also can swell from the moisture. If it's not too bad you can try a few coats of a water based polyurethane to seal the areas temporarily until you can replace it.
You need to keep the humidity low and the particle board away from sources of water.
Use a solvent-based polyurethane (exterior grade) on the particle board that is crumbling. This will soak in and hopefully glue it all back together. Think about gluing a thin plastic of some sort over the area so that the particleboard isn't exposed to moisture anymore.
I got this off of Google after checking that my idea was correct... LOL.
Get wood glue & sawdust. Apply glue add sawdust. Let dry, prime and paint then cover with Thompsons water seal. Dont forget to use silicone caulking around taps and edge of sink
Glad I could help. I made sure I verified the info. I used to be a remodeling and renovation contractor and that was all I could think of that might work. Best of luck to you!

Once it starts to deteriorate it's done. Need to replace. Hopefully you've repaired the water leak that caused it.
