Description
A flaw was found in the Linux kernel's ESP-in-TCP (Encapsulating Security Payload in Transmission Control Protocol) implementation. Certain error-handling routines fail to properly release allocated network socket buffers, resulting in a memory leak. An attacker capable of triggering these error conditions can cause gradual system memory exhaustion, potentially leading to a Denial of Service (DoS).
