Hi, there!
The symptom of an oak dropping all of its leaves this time of year sounds like oak wilt.

However, oak wilt doesn't usually come with scabs on the leaves? Please read through the bulletin and if the symptoms don't match what you are seeing in the tree, then please send along a picture of the leaves and we can go from there.
Thank you!
