In the Linux kernel, the following vulnerability has been resolved: iommufd: Break the loop on failure in iommufd_fault_fops_read() On a copy_to_user() failure inside the inner list_for_each_entry, only the inner loop breaks; the outer while re-fetches the just-restored fault group and retries the failing copy_to_user() forever, spinning the reader at 100% CPU with fault->mutex held. Check rc after the inner loop and break the outer while as well.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4745 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - iommufd: Break the loop on failure in iommufd_fault_fops_read() On a copy_to_user() failure inside the     inner list_for_each_entry, only the inner loop breaks; the outer while re-fetches the just-restored fault     group and retries the failing copy_to_user() forever, spinning the reader at 100% CPU with fault->mutex     held. Check rc after the inner loop and break the outer while as well. (CVE-2026-64290)

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