Description
CVE-2026-124759 is a high-severity vulnerability in RT-Labs P-Net prior to version 1.0.4. The vulnerability arises from improper origin validation of received RTA alarm frames, allowing an adjacent network host to disrupt or forge alarm notifications. This can lead to aborting established Application Relationships or injecting malicious alarm data.
