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 · unedited
Unchecked 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::SetFieldAction::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 · high confidence

A NULL pointer dereference vulnerability exists in the SetFieldAction::unpack function within libfluid's of13 module. The function fails to check a return value before using it, leading to dereferencing a NULL pointer when the return value is NULL. This can cause a denial of service via application crash.

MitigationAdd proper validation checks for return values in the SetFieldAction::unpack function before dereferencing them. Ensure all unpack operations return valid pointers or proper error codes that are validated before use.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm libfluid installation
    Locate libfluid library files or source code in your environment. Check for files named libfluid or directories containing 'fluid' in the project structure.
    Affected if libfluid Msg version 0.1.0 is present in the environment
  2. Verify libfluid Msg version
    Check the version identifier of the installed libfluid Msg library. Compare against the affected version 0.1.0.
    Affected if The installed version is exactly 0.1.0
  3. Check if of13 module is in use
    Inspect project dependencies or build configuration to determine if the of13 (OpenFlow 1.3) module is compiled or imported.
    Affected if The of13 module is included in the build or runtime dependencies
  4. Identify SetFieldAction::unpack usage
    Search codebase for calls to SetFieldAction::unpack function or references to SetFieldAction class in the of13 module.
    Affected if Codebase contains usage of SetFieldAction::unpack from the of13 module
  5. Inspect return value handling
    Examine the SetFieldAction::unpack function implementation in the of13 module source code. Look for proper NULL checks on return values before dereferencing.
    Affected if The function lacks validation of return values before use, allowing NULL pointer dereference

The environment is affected if libfluid Msg version 0.1.0 is in use and the of13 module with SetFieldAction::unpack is being exercised without proper NULL checks on return values.
