  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  iio: gyro: itg3200: fix i2c read into the wrong...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  iio: gyro: itg3200: fix i2c read into the wrong stack location  itg3200_read_all_channels() takes \u0060__be16 *buf\u0027 as a parameter and fills the i2c_msg destination as \u0060(char *)\u0026buf\u0027. Since \u0060buf\u0027 is the parameter (a pointer), \u0060\u0026buf\u0027 is the address of the local pointer slot on the stack of itg3200_read_all_channels(), not the address of the caller\u0027s scan buffer. The (char *) cast hides the type mismatch.  i2c_transfer() therefore writes ITG3200_SCAN_ELEMENTS * sizeof(s16) = 8 bytes into the parameter\u0027s stack slot, which is discarded when the function returns. The caller\u0027s scan buffer in itg3200_trigger_handler() is never written to, so iio_push_to_buffers_with_timestamp() pushes uninitialised stack contents to userspace via /dev/iio:deviceX every scan -- both a functional bug (no actual gyroscope or temperature data is delivered through the triggered buffer) and an information leak.  The non-buffered read_raw() path is unaffected: it goes through itg3200_read_reg_s16() which uses \u0060\u0026out\u0027 on a local s16 value, where that is correct.  Drop the spurious \u0060\u0026\u0027 so the i2c read writes into the caller\u0027s buffer.",
