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

  - netfilter: nfnetlink_osf: fix divide-by-zero in OSF_WSS_MODULO nf_osf_match_one() computes ctx->window %     f->wss.val in the OSF_WSS_MODULO branch with no guard for f->wss.val == 0. A CAP_NET_ADMIN user can add     such a fingerprint via nfnetlink; a subsequent matching TCP SYN divides by zero and panics the kernel.
    Reject the bogus fingerprint in nfnl_osf_add_callback() above the per-option for-loop. f->wss is per-     fingerprint, not per-option, so the check must run regardless of f->opt_num (including 0). Also reject     wss.wc >= OSF_WSS_MAX; nf_osf_match_one() already treats that as should not happen. Crash: Oops: divide     error: 0000 [#1] SMP KASAN NOPTI RIP: 0010:nf_osf_match_one (net/netfilter/nfnetlink_osf.c:98) Call Trace:
