Descriptions
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Use after free in __vmbus_open()
The "open_info" variable is added to the &vmbus_connection.chn_msg_list,
but the error handling frees "open_info" without removing it from the
list. This will result in a use after free. First remove it from the
list, and then free it.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Controladores: hv: vmbus: Usar después de liberar en __vmbus_open() La variable "open_info" se agrega a &vmbus_connection.chn_msg_list, pero el manejo de errores libera "open_info" sin eliminarlo de la lista. Esto resultará en un uso posterior gratuito. Primero elimínelo de la lista y luego libérelo.
