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

  - A flaw was found in Cockpit. A local authenticated user with control over a target account's home     directory can exploit a privileged symlink dereference vulnerability in the `ssh-add-public-key.sh`     helper. When this helper runs with elevated privileges, it can be tricked into following attacker-     controlled symlinks within the `.ssh` or `authorized_keys` paths. This allows the attacker to arbitrarily     change file ownership and modes, potentially leading to local privilege escalation and impacting the     integrity, confidentiality, and availability of the system. (CVE-2026-91151)

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