## Description

In the Linux kernel, the following vulnerability has been resolved:  iio: buffer: hw-consumer: free scan_mask on buffer release  The scan_mask lifetime changed in commit 9a2e1233d38c ("iio: buffer: hw-consumer: remove redundant scan_mask flexible array").  Before that change, the scan mask storage was embedded in struct hw_consumer_buffer, so iio_hw_buf_release() could free the whole allocation with a single kfree(hw_buf).  That commit moved the scan mask to a separate bitmap_zalloc() allocation stored in buffer.scan_mask, but left iio_hw_buf_release() unchanged.  Free the scan mask in iio_hw_buf_release() before freeing the buffer wrapper.
