Description
CVE-2026-124760 is a low-severity vulnerability in RT-Labs P-Net versions before 1.0.4. The issue involves improper handling of alarm receiver state when parsing alarm notifications fails, causing subsequent alarms of the same priority to be discarded without acknowledgment until the Application Relationship is released. The attacker requires adjacent network access and an established Application Relationship to exploit this flaw. The Application Relationship and cyclic data exchange continue functioning despite the issue. A fix is available in version 1.0.4.
