"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: wwan: t7xx: check skb_clone in control TX\n\nt7xx_port_ctrl_tx() clones each skb fragment before passing it to the\nport transmit path. The clone is used immediately to set cloned->len, so\nan skb_clone() failure results in a NULL pointer dereference.\n\nCheck the clone before using it. If previous fragments were already\nqueued, preserve the driver's existing partial-write behavior by\nreturning the number of bytes submitted so far."
