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

  - proc: protect ptrace_may_access() with exec_update_lock (part 1) Fix the easy cases where procfs currently     calls ptrace_may_access() without exec_update_lock protection, where the fix is to simply add the extra     lock or use mm_access(): - do_task_stat(): grab exec_update_lock - proc_pid_wchan(): grab exec_update_lock
    - proc_map_files_lookup(): use mm_access() instead of get_task_mm() - proc_map_files_readdir(): use     mm_access() instead of get_task_mm() - proc_ns_get_link(): grab exec_update_lock - proc_ns_readlink():
    grab exec_update_lock (CVE-2026-64371)

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