The version of Google Chrome installed on the remote macOS host is prior to 76.0.3809.132. It is, therefore, affected by use-after-free in Blink as referenced in the 2019_08_stable-channel-update-for-desktop_26 advisory.

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