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

  - Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol     suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an     unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to     the same domain (e.g., h.local as a CNAME for h.local). This causes unbounded recursion in the     lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where     AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by     nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524. (CVE-2026-24401)

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