Descriptions

In FreeBSD 12.1-STABLE before r356606 and 12.1-RELEASE before 12.1-RELEASE-p3, driver specific ioctl command handlers in the ixl network driver failed to check whether the caller has sufficient privileges allowing unprivileged users to trigger updates to the device's non-volatile memory.

En FreeBSD versiones 12.1-STABLE anteriores a r356606 y versiones 12.1-RELEASE anteriores a 12.1-RELEASE-p3, los manejadores del comando ioctl específico del controlador en el controlador de red ixl presentaron un fallo al comprobar si él que llama tiene suficientes privilegios que permite a los usuarios no privilegiados activar actualizaciones en la memoria no volátil del dispositivo .
