CVE-2025-40071

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> tty: n_gsm: Don&amp;#39;t block input queue by waiting MSC<br /> <br /> Currently gsm_queue() processes incoming frames and when opening<br /> a DLC channel it calls gsm_dlci_open() which calls gsm_modem_update().<br /> If basic mode is used it calls gsm_modem_upd_via_msc() and it<br /> cannot block the input queue by waiting the response to come<br /> into the same input queue.<br /> <br /> Instead allow sending Modem Status Command without waiting for remote<br /> end to respond. Define a new function gsm_modem_send_initial_msc()<br /> for this purpose. As MSC is only valid for basic encoding, it does<br /> not do anything for advanced or when convergence layer type 2 is used.
