  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: wwan: t7xx: check skb_clone in control TX  t7xx_port_ctrl_tx() clones each skb fragment before passing it to the port transmit path. The clone is used immediately to set cloned-\u003elen, so an skb_clone() failure results in a NULL pointer dereference.  Check the clone before using it. If previous fragments were already queued, preserve the driver's existing partial-write behavior by returning the number of bytes submitted so far.",
