Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: Se corrige el use after free al revertir la tabla de terminación Cuando se tienen varios destinos con tablas de terminación y fallo el segundo o posteriores, el controlador revierte el uso de las tablas de términos, pero no restablece la asignación en attr->dests[num_vport_dests].termtbl, en cuyo caso se produce un use after free al liberar la regla. Se soluciona restableciendo la asignación de termtbl a nulo.
