Descriptions

TensorFlow is an open source platform for machine learning. When the `BaseCandidateSamplerOp` function receives a value in `true_classes` larger than `range_max`, a heap oob read occurs. We have patched the issue in GitHub commit b389f5c944cadfdfe599b3f1e4026e036f30d2d4. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.

TensorFlow es una plataforma de código abierto para aprendizaje automático. Cuando la función `BaseCandidateSamplerOp` recibe un valor en `true_classes` mayor que `range_max`, se produce una lectura fuera de los límites del heap. Hemos solucionado el problema en el commit de GitHub b389f5c944cadfdfe599b3f1e4026e036f30d2d4. La solución se incluirá en TensorFlow 2.11. También seleccionaremos este commit en TensorFlow 2.10.1, 2.9.3 y TensorFlow 2.8.4, ya que estos también se ven afectados y aún se encuentran en el rango admitido.
