CVE-2024-53076 iio: gts-helper: Fix memory leaks for the error path of iio_gts_build_avail_scale_table()

What is CVE-2024-53076?

CVE-2024-53076 is a high-severity denial of service vulnerability in Linux kernel, published on 19 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

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

iio: gts-helper: Fix memory leaks for the error path of iio_gts_build_avail_scale_table()

If per_time_scales[i] or per_time_gains[i] kcalloc fails in the for loop of iio_gts_build_avail_scale_table(), the err_free_out will fail to call kfree() each time when i is reduced to 0, so all the per_time_scales[0] and per_time_gains[0] will not be freed, which will cause memory leaks.

Fix it by checking if i >= 0.

Weakness: CWE-401
