Descriptions

In the Linux kernel, the following vulnerability has been resolved:

tty: n_gsm: require CAP_NET_ADMIN to attach N_GSM0710 ldisc

Any unprivileged user can attach N_GSM0710 ldisc, but it requires
CAP_NET_ADMIN to create a GSM network anyway.

Require initial namespace CAP_NET_ADMIN to do that.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tty: n_gsm: requiere CAP_NET_ADMIN para adjuntar el ldisc N_GSM0710. Cualquier usuario sin privilegios puede adjuntar el ldisc N_GSM0710, pero de todos modos requiere CAP_NET_ADMIN para crear una red GSM. Requiere el espacio de nombres inicial CAP_NET_ADMIN para hacer eso.
