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

  - In the Linux kernel, the following vulnerability has been resolved: fuse: wait for FR_FINISHED on     abort_on_kill to prevent use-after-free The abort_on_kill path in request_wait_answer() calls     fuse_abort_conn() and returns without waiting for FR_FINISHED. If fuse_dev_do_write() is concurrently     processing the same request (FR_LOCKED set), the caller frees req->args while it is still being accessed,     causing a use-after-free. Fix this by jumping to the existing wait_event(FR_FINISHED) instead of returning     early. The wait will not hang because fuse_abort_conn() ensures all requests are ended. (CVE-2026-80857)

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