  "description": "In the Linux kernel, the following vulnerability has been resolved:  smb: server: make use of smbdirect_socket.send_io.bcredits  It turns out that our code will corrupt the stream of reassabled data transfer messages when we trigger an immendiate (empty) send.  In order to fix this we\u0027ll have a single \u0027batch\u0027 credit per connection. And code getting that credit is free to use as much messages until remaining_length reaches 0, then the batch credit it given back and the next logical send can happen.",
