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

  - tap: free page on error paths in tap_get_user_xdp() tap_get_user_xdp() rejects a frame shorter than     ETH_HLEN with -EINVAL, and returns -ENOMEM when build_skb() fails. Both paths jump to the err label     without freeing the page that vhost_net_build_xdp() allocated for the frame. tap_sendmsg() discards the     per-buffer return value and always returns 0, so vhost_tx_batch() takes the success path and never frees     the page; each rejected frame in a batch leaks one page-frag chunk. Free the page on both error paths,     before the skb is built. This is the tap counterpart of the same leak in tun_xdp_one(). (CVE-2026-46320)

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