      "value": "By passing invalid javascript code where await and yield were called upon non-async and non-generator getter/setter functions, Hermes would invoke generator functions and error out on invalid await/yield positions. This could result in segmentation fault as a consequence of type confusion error, with a low chance of RCE. This issue affects Hermes versions prior to v0.10.0."

Esto podr\u00eda resultar en un fallo de segmentaci\u00f3n como consecuencia de un error de confusi\u00f3n de tipos, con una baja probabilidad de RCE.
