Description
Impact
The function tf.raw_ops.LookupTableImportV2 cannot handle scalars in the values parameter and gives an NPE.
import tensorflow as tf
v = tf.Variable(1)
@tf.function(jit_compile=True)
def test():
func = tf.raw_ops.LookupTableImportV2
para={'table_handle': v.handle,'keys': [62.98910140991211, 94.36528015136719], 'values': -919}
y = func(**para)
return y
print(test())
Patches
We have patched the issue in GitHub commit 980b22536abcbbe1b4a5642fc940af33d8c19b69.
The fix will be included in TensorFlow 2.12. We will also cherrypick this commit on TensorFlow 2.11.1.

tensorflowgoogleDetection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tensorflow, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update tensorflow to 2.11.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-25672 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
