A specific malformed fragmented packet type (fragmented packets may be generated automatically by devices that send large amounts of data) can cause a major nonrecoverable fault (MNRF) Rockwell Automationโs ControlLogix 5580, Guard Logixย 5580,ย CompactLogix 5380,ย and 1756-EN4TR. If exploited, the affected product will become unavailable and require a manual restart to recover it. Additionally, an MNRF could result in a loss of view and/or control of connected devices.
