CVE-2025-32399
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn Unchecked Input for Loop Condition in RT-Labs P-Net version 1.0.1 or earlier allows an attacker to cause IO devices that use the library to enter an infinite loop by sending a malicious RPC packet.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceRT-Labs P-Net versions 1.0.1 and earlier contain an unchecked input vulnerability in loop condition handling within the RPC packet processing logic. An attacker can send a specially crafted malicious RPC packet to cause the affected IO device to enter an infinite loop, resulting in denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify P-Net library versionLocate the P-Net library binary or source package and query its version information using package manager commands, library file metadata, or version strings in the binary (e.g., strings command on libpnet.so)Affected if The installed version is 1.0.1 or any version prior to 1.0.2
-
Confirm P-Net is running as an IO deviceInspect the P-Net configuration or running process to determine if the device is operating in IO device mode (check config files, process arguments, or device role settings)Affected if P-Net is configured and running as an IO device, as the vulnerability affects IO device packet processing
-
Verify RPC packet handling is activeCheck if RPC services are enabled in the P-Net configuration or network settings, and monitor for RPC traffic on the network interface used by P-NetAffected if RPC packet processing is enabled and the device is processing RPC packets on the network
-
Review application logs for infinite loop symptomsExamine system and application logs for indicators of the device becoming unresponsive, high CPU usage, or watchdog timeouts that may indicate an infinite loop conditionAffected if The device exhibits symptoms consistent with an infinite loop (unresponsiveness, high CPU, restart loops)
The environment is affected if P-Net version is 1.0.1 or earlier, the device is operating as an IO device, and RPC packet processing is active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.0.2
Update P-Net library to a version beyond 1.0.1 where input validation has been implemented for loop conditions, or implement proper bounds checking and input validation on RPC packet data before use in loop statements.
P-Net 1.0.2
- Upgrade P-Net library to version 1.0.2 or later to resolve the unchecked input for loop condition vulnerability
