CVE-2026-68337

A flaw was found in the Linux kernel. The BPF (Berkeley Packet Filter) redirect helpers, specifically bpf_redirect*() and skb_do_redirect(), can attempt to dereference a null pointer if a bpf_net_context is not established. This can occur when certain BPF programs are attached to a network queueing discipline (qdisc). A local attacker could exploit this to trigger a null pointer dereference, leading to a system crash and a Denial of Service (DoS).
