In the Linux kernel, the following vulnerability has been resolved:

iio: gts-helper: Fix memory leaks in iiogtsbuildavailscale_table()

modprobe iio-test-gts and rmmod it, then the following memory leak occurs:

It includes 55 times "size 64" memory leaks, which correspond to 5 times test_init_iio_gain_scale() calls with gts_test_gains size 10 (10size(int)) and gtstestitimes size 5. It also includes 51 times "size 16" memory leak, which correspond to one time __test_init_iio_gain_scale() call with gts_test_gains_gain_low size 3 (3size(int)) and gtstestitimes size 5.

The reason is that the pertimegains[i] is not freed which is allocated in the "gts->numitime" for loop in iiogtsbuildavailscaletable().
