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

  - net: marvell: prestera: fix NULL dereference on devlink_alloc() failure devlink_alloc() may return NULL on     allocation failure, but prestera_devlink_alloc() unconditionally calls devlink_priv() on the returned     pointer. This leads to a NULL pointer dereference if devlink allocation fails. Add a check for a NULL     devlink pointer and return NULL early to avoid the crash. (CVE-2026-23019)

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