The version of cri-o installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-1708 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of cri-o installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected
by a vulnerability as referenced in the CVE-2022-1708 advisory.
- A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with
access to the Kube API. The ExecSync request runs commands in a container and logs the output of the
command. This output is then read by CRI-O after command execution, and it is read in a manner where the
entire file corresponding to the output of the command is read in. Thus, if the output of the command is
large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of
the command. The highest threat from this vulnerability is system availability. (CVE-2022-1708)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
