      "title": "Input: usbtouchscreen - clamp NEXIO data_len/x_len to URB buffer size",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: usbtouchscreen - clamp NEXIO data_len/x_len to URB buffer size\n\nnexio_read_data() pulls data_len and x_len from a packed __be16 header\nin the device's interrupt packet and then walks packet->data[0..x_len)\nand packet->data[x_len..data_len) comparing each byte against a\nthreshold.\n\nBoth fields are 16-bit on the wire (max 65535).  The existing\nadjustments shave at most 0x100 / 0x80 off, so the loop bound can still\nreach roughly 0xfeff.  The URB transfer buffer for NEXIO is rept_size\n(1024) bytes from usb_alloc_coherent(), with the first 7 occupied by the\npacked header — so packet->data[] has 1017 valid bytes.  read_data()\ncallbacks are not given urb->actual_length, and nothing else bounds the\nwalk.\n\nA device that lies about its length can get a ~64 KiB out-of-bounds read\npast the coherent DMA allocation.  The first index whose byte exceeds\nNEXIO_THRESHOLD lands in begin_x / begin_y and from there into the\nreported touch coordinates, so adjacent kernel memory contents leak to\nuserspace as ABS_X / ABS_Y events.  Far enough out, the read can also\nhit an unmapped page and fault.\n\nFix this all by clamping data_len to the buffer's data[] capacity and\nx_len to data_len.",
