type enforcement in BPF_LINK_CREATE\n\nbpf_prog_attach uses attach_type_to_prog_type to enforce proper\nattach type for BPF_PROG_TYPE_CGROUP_SKB. link_create uses\nbpf_prog_get and relies on bpf_prog_attach_check_attach_type\nto properly verify prog_type <> attach_type association.\n\nAdd missing attach_type enforcement for the link_create case.\nOtherwise, it's currently possible to attach cgroup_skb prog\ntypes to other cgroup hooks.","state":0,"publishedAt":"2024-06-19T13:35:32.222+00:00","modifiedAt":"2026-10-27T15:53:48.399+00:00","affected":[{"ecosystem":"Vendor
