"value": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: buffer: hw-consumer: free scan_mask on buffer release\n\nThe scan_mask lifetime changed in commit 9a2e1233d38c (\"iio: buffer:\nhw-consumer: remove redundant scan_mask flexible array\").\n\nBefore that change, the scan mask storage was embedded in struct\nhw_consumer_buffer, so iio_hw_buf_release() could free the whole\nallocation with a single kfree(hw_buf).\n\nThat commit moved the scan mask to a separate bitmap_zalloc() allocation\nstored in buffer.scan_mask, but left iio_hw_buf_release() unchanged.\n\nFree the scan mask in iio_hw_buf_release() before freeing the buffer\nwrapper."
