Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

A replica-set database server node does not limit or reclaim internal wait records created while handling a client-supplied read option that names a point in time the node will never reach. A party with network access and no credentials can cause these records to accumulate without bound and persist after the requests end, which may make the server run out of memory and become unavailable.
