Can my mother get any benefits due to my father being a Korean War vet?

My father was a Korean War veteran and was diagnosed as fully disabled from the war in his later years from shrapnel and total hearing loss and was receiving financial benefits due to this. He passed away last year, leaving my mother suddenly without a husband or the finances. Now she is in danger of losing their home of over 21 years because her meager pension isn't enough to cover all the expenses. Is she entitled to anything at all?
