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
Out-of-bounds Read vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of13::TableFeaturePropOXM::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 confidence

An out-of-bounds read vulnerability exists in the fluid_msg::of13::TableFeaturePropOXM::unpack routine of libfluid 0.1.0. This vulnerability occurs when parsing OpenFlow 1.3 Table Feature Property messages with OXM (OpenFlow Extensible Match) fields, where improper bounds validation during message unpacking allows reading memory beyond allocated buffers.

MitigationUpdate to a patched version of libfluid if available, or implement proper bounds checking in the TableFeaturePropOXM::unpack routine to validate buffer lengths before reading OXM field data.

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. Identify libfluid msg library installation
    Search for libfluid library files or headers in the system. Look for files named libfluid-msg, fluid-msg, or check package managers for installed libfluid packages.
    Affected if libfluid msg library version 0.1.0 is present on the system
  2. Verify exact version of libfluid-msg
    Check the version of the installed libfluid msg library through package metadata, library version symbols, or by inspecting version information in library files.
    Affected if The installed version is exactly 0.1.0 (any other version is not affected)
  3. Confirm OpenFlow 1.3 support is enabled
    Inspect the application or service configuration to determine if OpenFlow 1.3 protocol support is enabled. Look for of13, openflow13, or OFP_VERSION in configuration files.
    Affected if OpenFlow 1.3 protocol support is enabled and in use
  4. Check for Table Feature Property message processing
    Monitor or inspect network traffic and application logs for incoming OpenFlow 1.3 Table Feature Property messages (OFPT_TABLE_FEATURES) with OXM fields. Check if the application processes OFPT_TABLE_FEATURES messages.
    Affected if The application processes OpenFlow 1.3 Table Feature Property messages containing OXM (OpenFlow Extensible Match) fields
  5. Inspect TableFeaturePropOXM unpack code
    If source code is available, locate and review the fluid_msg::of13::TableFeaturePropOXM::unpack routine for bounds checking logic. Look for buffer length validation before OXM field data access.
    Affected if The unpack routine lacks proper bounds validation before reading OXM field data from buffers

A system is affected only if it runs libfluid msg version 0.1.0 with OpenFlow 1.3 enabled and processes Table Feature Property messages containing OXM fields.
