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: io_uring: fix overflows checks in     provide buffers Colin reported before possible overflow and sign extension problems in     io_provide_buffers_prep(). As Linus pointed out previous attempt did nothing useful, see d81269fecb8ce     (io_uring: fix provide_buffers sign extension). Do that with help of check_<op>_overflow helpers. And     fix struct io_provide_buf::len type, as it doesn't make much sense to keep it signed. (CVE-2021-47040)

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