Reading these invalid values in the\nregister can lead to out-of-bound memory access. So, fix\nby using the saved server TID base when clearing filters."

Leer estos valores no v\u00e1lidos en el registro puede provocar un acceso a la memoria fuera de l\u00edmites. Por lo tanto, solucione el problema utilizando la base TID del servidor guardado al borrar los filtros."
