The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - bpf: Prevent decl_tag from being referenced in func_proto arg Syzkaller managed to hit another decl_tag     issue: btf_func_proto_check kernel/bpf/btf.c:4506 [inline] btf_check_all_types kernel/bpf/btf.c:4734     [inline] btf_parse_type_sec+0x1175/0x1980 kernel/bpf/btf.c:4763 btf_parse kernel/bpf/btf.c:5042 [inline]     btf_new_fd+0x65a/0xb00 kernel/bpf/btf.c:6709 bpf_btf_load+0x6f/0x90 kernel/bpf/syscall.c:4342

    prevent decl_tag from being referenced in func_proto) but for the argument. (CVE-2022-50883)

Note that Nessus relies on the presence of the package as reported by the vendor.
