# Android crypto HAL: use-after-free race lets remote code run

A race condition in the decrypt path of CryptoHalHidl.cpp, an Android hardware crypto component, can cause a use-after-free. The description says this could lead to remote code execution without extra privileges or user interaction.

_Summary, check and fix written by a model from the sources; labelled as such._
