CVE-2022-49867

In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix memory leak in ipc_wwan_dellink IOSM driver registers network device without setting the needs_free_netdev flag, and does NOT call free_netdev() when unregisters network device, which causes a memory leak. This patch sets needs_free_netdev to true when registers network device, which makes netdev subsystem call free_netdev() automatically after unregister_netdevice().

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: wwan: iosm: se corrige una fuga de memoria en ipc_wwan_dellink. El controlador IOSM registra el dispositivo de red sin configurar el indicador needs_free_netdev y NO llama a free_netdev() al cancelar el registro del dispositivo de red, lo que provoca una fuga de memoria. Este parche establece needs_free_netdev como verdadero al registrar el dispositivo de red, lo que hace que el subsistema netdev llame automáticamente a free_netdev() después de cancelar el registro de netdevice().
