In the Linux kernel, the following vulnerability has been resolved: igb: Fix potential invalid memory access in igb_init_module() The pci_register_driver() can fail and when this happened, the dca_notifier needs to be unregistered, otherwise the dca_notifier can be called when igb fails to install, resulting to invalid memory access.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: igb: Se corrige un posible acceso no válido a la memoria en igb_init_module(). pci_register_driver() puede fallar y cuando esto sucede, se debe anular el registro de dca_notifier; de lo contrario, se puede llamar a dca_notifier cuando igb no se instala, lo que genera un acceso no válido a la memoria.
