Summary
In 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.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: octeon_ep: Se solucion\u00f3 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 funci\u00f3n ndo_stop espec\u00edfica 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 funci\u00f3n de detenci\u00f3n espec\u00edfica 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 est\u00e1 inactivo, no se llama a ndo_stop."
