CVE-2025-40578

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions). Affected devices do not properly handle multiple incoming Profinet packets received in rapid succession. An unauthenticated remote attacker can exploit this flaw by sending multiple packets in a very short time frame, which leads to a crash of the dcpd process.
