In the Linux kernel, the following vulnerability has been resolved: tls: stop recv() if initial processrxlist gave us non-DATA If we have a non-DATA record on the rxlist and another record of the same type still on the queue, we will end up merging them: - processrxlist copies the non-DATA record - we start the loop and process the first available record since it's of the same type - we break out of the loop since the record was not DATA Just check the record type and jump to the end in case processrx_list did some work.
