n the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix use-after-free when reverting termination table When having multiple dests with termination tables and second one or afterwards fails the driver reverts usage of term tables but doesn't reset the assignment in attr->dests[num_vport_dests].termtbl which case a use-after-free when releasing the rule. Fix by resetting the assignment of termtbl to null.

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.
