Description

A flaw was found in the Linux kernel's X.25 networking component. This vulnerability, a double free, occurs when a socket buffer (skb) allocation fails in x25_queue_rx_frame, causing the same skb to be freed twice. This improper memory handling can lead to a system crash, resulting in a Denial of Service (DoS).
