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

  - net-shapers: don't free reply skb after genlmsg_reply() genlmsg_reply() hands the reply skb to netlink,     and netlink_unicast() consumes it on all return paths, whether the skb is queued successfully or freed on     an error path. net_shaper_nl_get_doit() and net_shaper_nl_cap_get_doit() currently jump to free_msg after     genlmsg_reply() fails and call nlmsg_free(msg), which can hit the same skb twice. Return the     genlmsg_reply() error directly and keep free_msg only for pre-reply failures. (CVE-2026-43481)

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