CVE-2024-31175
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 · uneditedUnchecked Return Value to NULL Pointer Dereference vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of13::TablePropertiesList::unpack. This issue affects libfluid: 0.1.0.
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 · moderate confidenceA NULL pointer dereference vulnerability exists in libfluid's of13::TablePropertiesList::unpack function due to an unchecked return value. When unpacking OpenFlow 1.3 TablePropertiesList messages, if the routine returns NULL (e.g., from a parsing failure), the code dereferences this NULL pointer without validation, causing a crash. This can be triggered by malformed OpenFlow messages on the network, leading to 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.
-
Confirm libfluid presenceIdentify whether the Opennetworking libfluid library is installed or embedded in your environment. Search for packages or binaries named libfluid, libfluid-msg, or containing 'fluid' in the name.Affected if libfluid is present in the environment
-
Check libfluid-msg versionDetermine the exact version of the libfluid-msg component. Compare your installed version against the affected range: version = 0.1.0Affected if The installed version is libfluid-msg version 0.1.0
-
Verify OpenFlow 1.3 module usageDetermine whether your deployment utilizes the of13 (OpenFlow 1.3) module for processing OpenFlow messages. Review application code or configuration for imports or references to of13 functionality.Affected if The of13 module is being used to process OpenFlow 1.3 messages
-
Assess network exposure to OpenFlowIdentify whether the system accepts OpenFlow connections from the network. Review firewall rules, network ACLs, and service configurations for exposed OpenFlow ports (typically 6653/6633).Affected if The libfluid service is network-accessible and processes incoming OpenFlow messages
-
Review for crash evidenceExamine system logs, application logs, and core dumps for crashes occurring in the TablePropertiesList::unpack function or related to OpenFlow message parsing.Affected if Crashes have occurred during OpenFlow 1.3 TablePropertiesList message processing
You are affected if you are running libfluid-msg version 0.1.0 with the of13 module enabled and network-accessible OpenFlow message processing.

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.
From vendor dataImplement proper NULL check validation on return values before dereferencing in the TablePropertiesList::unpack function. Ensure all unpack operations validate their results and handle errors gracefully rather than proceeding with NULL pointers.
