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