The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2729 advisory.

  • kernel: use-after-free in net/bluetooth/hci_event.c when destroying an hci_chan (CVE-2021-33034)

  • 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.
