A race condition was found in the GSM 0710 tty multiplexor in the Linux
kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl
on the same tty file descriptor with the gsm line discipline enabled, and
can lead to a use-after-free problem on a struct gsm_dlci while restarting
the gsm mux. This could allow a local unprivileged user to escalate their
privileges on the system.
