  "details": "In the Linux kernel, the following vulnerability has been resolved:  can: peak_usb: add bounds check for USB channel index  The channel control index ctrl_idx is derived from rx-\u003elen which comes directly from a device USB payload. The mask 0x0f allows values 0-15, but the array size of usb_if-\u003edev[] is only 2. Values 2-15 cause heap out-of-bounds read, eventually causing kernel panic in the IRQ context.  Add bounds checking for ctrl_idx before the array access in both pcan_usb_pro_handle_canmsg() and pcan_usb_pro_handle_error().",
