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

  - gpio: cdev: make sure the cdev fd is still active before emitting events With the final call to fput() on     a file descriptor, the release action may be deferred and scheduled on a work queue. The reference count     of that descriptor is still zero and it must not be used. It's possible that a GPIO change, we want to     notify the user-space about, happens AFTER the reference count on the file descriptor associated with the     character device went down to zero but BEFORE the .release() callback was called from the workqueue and so     BEFORE we unregistered from the notifier. Using the regular get_file() routine in this situation triggers     the following warning: struct file::f_count incremented from zero; use-after-free condition present! So     use the get_file_active() variant that will return NULL on file descriptors that have been or are being     released. (CVE-2025-40249)

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