3S-Smart Software Solutions GmbH CODESYS V3 OPC UA Server, all versions 3.5.11.0 to 3.5.15.0, allows an attacker to send crafted requests from a trusted OPC UA client that cause a NULL pointer dereference, which may trigger a denial-of-service condition.

Does this matter?

Lower severity and a low EPSS score (1.36%). Track it; it rarely justifies an emergency change on its own.
