In the Linux kernel, the following vulnerability has been resolved:
iio: accel: mma8452: handle I2C read error(s) in mma8452_read()
Currently, If i2c_smbus_read_i2c_block_data() fails but mma8452_set_runtime_pm_state() succeeds, mma8452_read() returns 0.
As a result, the caller mma8452_read_raw() assumes the read was successful and proceeds to use a buffer containing uninitialized stack memory.
Add proper checking of the I2C read return value and propagate errors to the caller.
