Echo: linux: security update to 6.12.57-1

medium Tenable Cloud Security Plugin ID 461172

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: tty: n_gsm: Don't block input queue by
 waiting MSC Currently gsm_queue() processes incoming frames and when opening a DLC channel it calls
 gsm_dlci_open() which calls gsm_modem_update(). If basic mode is used it calls gsm_modem_upd_via_msc() and
 it cannot block the input queue by waiting the response to come into the same input queue. Instead allow
 sending Modem Status Command without waiting for remote end to respond. Define a new function
 gsm_modem_send_initial_msc() for this purpose. As MSC is only valid for basic encoding, it does not do
 anything for advanced or when convergence layer type 2 is used. (CVE-2025-40071)

Solution

Update the linux library and its related packages to version 6.12.57-1 or later.
