Vulnerability in tensorflow (CVE-2022-41887)
Summary
Vulnerability in tensorflow (CVE-2022-41887). Risk of unauthorized operations or information disclosure. Exploitable via tf.keras.losses.poisson. Mitigation: upgrade to 2.10.1 or later.
Original description
The description as published by the source.
TensorFlow is an open source platform for machine learning. tf.keras.losses.poisson receives a y_pred and y_true that are passed through functor::mul in BinaryOp. If the resulting dimensions overflow an int32, TensorFlow will crash due to a size mismatch during broadcast assignment. We have patched the issue in GitHub commit c5b30379ba87cbe774b08ac50c1f6d36df4ebb7c. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1 and 2.9.3, as these are also affected and still in supported range. However, we will not cherrypick this commit into TensorFlow 2.8.x, as it depends on Eigen behavior that changed between 2.8 and 2.9.

Refs: see the GHSA / vendor advisory / patched release linked on this page.
A vulnerability (CWE-131) exists in tensorflow. Attackers reach the vulnerable code path via tf.keras.losses.poisson.
Check the vendor advisory for the affected versions of tensorflow. Attack surface: tf.keras.losses.poisson / y_pred / y_true / BinaryOp.
Severity: ?. Risk of unauthorized operations or information disclosure.
Update to 2.10.1.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'tensorflow' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

-
1Identify exposure identify
grep -r 'tensorflow' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
tensorflowを grep し、稼働しているサービス・バージョンを把握する。 -
2Apply patch patch
Upgrade tensorflow to 2.10.1ステージング環境で 2.10.1 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。
-
3Post-deployment verification verify
Confirm patched version is live in productionパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
