I'm bumping the fixed-in-version to the latest release on maint-21 (21.3.8.20).  It contains this additional fix which we really should have:

    erts: Fix race on ErtsMonLnkDist in erts_net_message
    
    Problem:
    DistEntry.mld read without DistEntry locked. If connection goes
    down mld pointer may be NULL leading to VM crash.
    
    Solution:
    Copy DistEntry.mld pointer and schedule destruction of ErtsMonLnkDist
    with thread progress. ErtsMonLnkDist already prepared with its own
    mutex and 'alive' flag, but we make sure to handle correctly when
    ErtsMonLnkDist is not alive (connection is down).
