CVE-2026-2492

Local privilege escalation via HDF5 plugin loading

Published Feb 20, 2026 · Updated Feb 20, 2026

Uncontrolled plugin search in Google TensorFlow 2.17.0 allows local users to execute code as a target user through HDF5 plugin loading. TensorFlow's Keras HDF5 modules import h5py without first setting HDF5_PLUGIN_PATH to disable HDF5's default external-plugin search locations. Low-privileged code execution is required, and a planted plugin runs when a higher-privileged target imports the affected path.
