Description
In the Linux kernel, the following vulnerability has been resolved: rnbd-srv: Zero the rsp buffer before using it Before using the data buffer to send back the response message, zero it completely. This prevents any stray bytes to be picked up by the client side when there the message is exchanged between different protocol versions.
