Description

A flaw was found in the Linux kernel. When a User Datagram Protocol (UDP) socket is configured with a sockmap, and a BPF (Berkeley Packet Filter) program attached to it calls a socket-lookup helper, the `skb->dev` field is not properly cleared. This improper handling of the `skb->dev` field can lead to a general protection fault, resulting in a Denial of Service (DoS) condition. A local attacker with the necessary permissions to load BPF programs could potentially trigger this vulnerability.
