Description

A flaw was found in the Linux kernel. When the espintcp component processes network traffic using asynchronous cryptography, a memory leak can occur. This happens because a socket buffer (skb) is not correctly released if the transmit queue becomes full. This continuous leak of memory can lead to resource exhaustion, potentially allowing a remote attacker to cause a Denial of Service (DoS) on the system.
