  "statement" : "Redhat has rated this vulnerability as Low severity as by default in RHEL system the BPF sockmap feature is disabled by default which is needed for this vulnerability to be exploitable, on top of that local access and higher privileges are required to exploit this vulnerability and a successful exploitation will only result in a denial of service vulnerability.",
