The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2714 advisory.

  • kernel: race condition for removal of the HCI controller (CVE-2021-32399)

  • kernel: size_t-to-int conversion vulnerability in the filesystem layer (CVE-2021-33909)

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