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

  - netfs: Fix read abandonment during retry Under certain circumstances, all the remaining subrequests from a     read request will get abandoned during retry. The abandonment process expects the 'subreq' variable to be     set to the place to start abandonment from, but it doesn't always have a useful value (it will be     uninitialised on the first pass through the loop and it may point to a deleted subrequest on later     passes). Fix the first jump to abandon: to set subreq to the start of the first subrequest expected to     need retry (which, in this abandonment case, turned out unexpectedly to no longer have NEED_RETRY set).
    Also clear the subreq pointer after discarding superfluous retryable subrequests to cause an oops if we do     try to access it. (CVE-2026-31435)

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