A vulnerability stemming from floating-point arithmetic precision errors exists in the QuickJS engine's implementation of TypedArray.prototype.indexOf() when a negative fromIndex argument is supplied.
* The fromIndex argument (read as a double variable, $d$) is used to calculate the starting position for the search.

* Due to the inher
