CVE-2024-50231
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
iio: gts-helper: Fix memory leaks in iio_gts_build_avail_scale_table()
modprobe iio-test-gts and rmmod it, then the following memory leak occurs:
It includes 5*5 times "size 64" memory leaks, which correspond to 5 times test_init_iio_gain_scale() calls with gts_test_gains size 10 (10*size(int)) and gts_test_itimes size 5. It also includes 5*1 times "size 16" memory leak, which correspond to one time __test_init_iio_gain_scale() call with gts_test_gains_gain_low size 3 (3*size(int)) and gts_test_itimes size 5.
The reason is that the per_time_gains[i] is not freed which is allocated in the "gts->num_itime" for loop in iio_gts_build_avail_scale_table().
