Denial-of-service in Rockwell Automation CompactLogix/GuardLogix 5380, CompactLogix 5480, and ControlLogix/GuardLogix 5580 controllers running boot firmware below version 1.072 lets a remote unauthenticated attacker write malformed file data that forces the device into a major non-recoverable fault (MNRF), halting the controlled process until manual recovery. The flaw carries a CVSS 4.0 base of 9.2 driven purely by availability impact (no data confidentiality or integrity loss) and requires no authentication or user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
