n the Linux kernel, the following vulnerability has been resolved: octeon_ep: Fix host hang issue during device reboot When the host loses heartbeat messages from the device, the driver calls the device-specific ndo_stop function, which frees the resources. If the driver is unloaded in this scenario, it calls ndo_stop again, attempting to free resources that have already been freed, leading to a host hang issue. To resolve this, dev_close should be called instead of the device-specific stop function.dev_close internally calls ndo_stop to stop the network interface and performs additional cleanup tasks. During the driver unload process, if the device is already down, ndo_stop is not called.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: octeon_ep: Se solucionó el problema de bloqueo del host durante el reinicio del dispositivo. Cuando el host pierde los mensajes de latido del dispositivo, el controlador llama a la función ndo_stop específica del dispositivo, que libera los recursos. Si el controlador se descarga en este caso, vuelve a llamar a ndo_stop para intentar liberar los recursos ya liberados, lo que provoca un problema de bloqueo del host. Para solucionar esto, se debe llamar a dev_close en lugar de a la función de detención específica del dispositivo. Dev_close llama internamente a ndo_stop para detener la interfaz de red y realiza tareas de limpieza adicionales. Durante el proceso de descarga del controlador, si el dispositivo ya está inactivo, no se llama a ndo_stop.
