The version of containerd installed on the remote host is prior to 1.4.6-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2NITRO-ENCLAVES-2022-016 advisory.

  - containerd is an open source container runtime with an emphasis on simplicity, robustness and portability.
    A bug was found in containerd where container root directories and some plugins had insufficiently     restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and     execute programs. When containers included executable programs with extended permission bits (such as     setuid), unprivileged Linux users could discover and execute those programs. When the UID of an     unprivileged Linux user on the host collided with the file owner or group inside a container, the     unprivileged Linux user on the host could discover, read, and modify those files. This vulnerability has     been fixed in containerd 1.4.11 and containerd 1.5.7. Users should update to these version when they are     released and may restart containers or update directory permissions to mitigate the vulnerability. Users     unable to update should limit access to the host to trusted users. Update directory permission on     container bundles directories. (CVE-2021-41103)

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