Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> can: gs_usb: gs_usb_receive_bulk_callback(): check actual_length before accessing data<br /> <br /> The URB received in gs_usb_receive_bulk_callback() contains a struct<br /> gs_host_frame. The length of the data after the header depends on the<br /> gs_host_frame hf::flags and the active device features (e.g. time<br /> stamping).<br /> <br /> Introduce a new function gs_usb_get_minimum_length() and check that we have<br /> at least received the required amount of data before accessing it. Only<br /> copy the data to that skb that has actually been received.<br /> <br /> [mkl: rename gs_usb_get_minimum_length() -&gt; +gs_usb_get_minimum_rx_length()]
