      "value": "The \"profiling.sampling\" module (Python 3.15+) and \"asyncio introspection capabilities\" (3.14+, \"python -m asyncio ps\" and \"python -m asyncio pstree\") features could be used to read and write addresses in a privileged process if that process connected to a malicious or \"infected\" Python process via the remote debugging feature. This vulnerability requires persistently and repeatedly connecting to the process to be exploited, even after the connecting process crashes with high likelihood due to ASLR."

      "value": "El módulo ’profiling.sampling’ (Python 3.15+) y las características de ’asyncio introspection capabilities’ (3.14+, ’python -m asyncio ps’ y ’python -m asyncio pstree’) podrían usarse para leer y escribir direcciones en un proceso privilegiado si ese proceso se conectara a un proceso Python malicioso o ’infectado’ a través de la función de depuración remota. Esta vulnerabilidad requiere conectarse de forma persistente y repetida al proceso para ser explotada, incluso después de que el proceso de conexión falle con alta probabilidad debido a ASLR."
