MEDIUMCVSS v4 6.0Vulnerability
CVE-2026-127123
P-Net before 1.0.4 releases the Application Relationship of an RPC session, without the abort procedure, when a fragment of a request has another data representation (endianness) than the first fragment of the call. The application is not told that the Application Relationship is gone, the cyclic data stops, and the resources of the Application Relationship are left referencing a cleared structure. Another host can then connect in its place. 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 do this with one PDU.
