As soon as it encounters a TLS control message, it would return an error. At that point, NFS can setup a kvec backed msg buffer and read in the control message such as a TLS alert. Msg iterator can advance the kvec pointer as a part of the copy process thus we need to revert the iterator before calling into the tls_alert_recv.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>sunrpc: fix handling of server side tls alerts</p> <p>Scott Mayhew discovered a security exploit in NFS over TLS in tls_alert_recv() due to its assumption it can read data from the msg iterator&#39;s kvec..</p> <p>kTLS implementation splits TLS non-data record payload between the control message buffer (which includes the type such as TLS aler or TLS cipher change) and the rest of the payload (say TLS alert&#39;s level/description) which goes into the msg payload buffer.</p> <p>This patch proposes to rework how control messages are setup and used by sock_recvmsg().</p> <p>If no control message structure is setup, kTLS layer will read and process TLS data record types.
