      "title": "iio: gyro: itg3200: fix i2c read into the wrong stack location",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: gyro: itg3200: fix i2c read into the wrong stack location\n\nitg3200_read_all_channels() takes `__be16 *buf' as a parameter and\nfills the i2c_msg destination as `(char *)&buf'. Since `buf' is the\nparameter (a pointer), `&buf' is the address of the local pointer\nslot on the stack of itg3200_read_all_channels(), not the address\nof the caller's scan buffer. The (char *) cast hides the type\nmismatch.\n\ni2c_transfer() therefore writes ITG3200_SCAN_ELEMENTS * sizeof(s16)\n= 8 bytes into the parameter's stack slot, which is discarded when\nthe function returns. The caller's scan buffer in\nitg3200_trigger_handler() is never written to, so\niio_push_to_buffers_with_timestamp() pushes uninitialised stack\ncontents to userspace via /dev/iio:deviceX every scan -- both a\nfunctional bug (no actual gyroscope or temperature data is\ndelivered through the triggered buffer) and an information leak.\n\nThe non-buffered read_raw() path is unaffected: it goes through\nitg3200_read_reg_s16() which uses `&out' on a local s16 value,\nwhere that is correct.\n\nDrop the spurious `&' so the i2c read writes into the caller's\nbuffer.",
