In the Linux kernel, the following vulnerability has been resolved:
tls: stop recv() if initial process_rx_list gave us non-DATA
If we have a non-DATA record on the rx_list and another record of the
same type still on the queue, we will end up merging them:
- process_rx_list 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 process_rx_list
did some work.
