Descriptions

An insufficient boundary validation in the USB code could lead to an out-of-bounds read on the heap, which could potentially lead to an arbitrary write and remote code execution.

Una validación de los límites insuficiente en el código USB podría provocar una lectura fuera de los límites en el montón, lo que potencialmente podría generar una escritura arbitraria y la ejecución remota de código.
