1. A system, comprising a processor and logic integrated with and/or executable by the processor, the logic being configured to: identify a security issue affecting a first peer in one or more secure transmission control protocol/user datagram protocol (TCP/UDP) sessions; inform a second peer about the security issue using the first peer of the one or more TCP/UDP sessions by causing the first peer to send a packet from the first peer to the second peer, the first peer being aware of the security issue prior to informing the second peer about the security issue, and the packet comprising an indication of the security issue in a TCP header of the packet; receive a second packet at the first peer indicating that the security issue has been acknowledged by the second peer, the second packet comprising a second TCP header having a security acknowledgement flag set therein to indicate that the security issue has been acknowledged by the second peer, wherein the security acknowledgement flag is stored within a reserve field of the second TCP header; and perform at least one action to resolve and/or avoid the security issue in response to identifying and/or being informed about the security issue at the first peer, the at least one action comprising informing, via a socket call or an extension of a socket call, one or more applications operating on the second peer via the one or more TCP/UDP sessions to limit information exchange based on a severity of the security issue.
