CVE-2026-124762

P-Net before 1.0.4 finds the RPC session of a received PDU by its activity UUID only, and a reject, fault or cancel PDU for the session aborts the Application Relationship, without checking that the PDU is the answer to a call of the device or where it comes from. A host with ADJACENT network access that has observed the activity UUID of the connection, which is sent in clear in every RPC request, can abort the Application Relationship with one PDU. It also allocates a session for an unknown activity UUID and changes the address stored for an existing session.
