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.

Affected products

Linux kernel: from 6.4 before 6.6.60; from 6.7 before 6.11.7; 6.12-rc1, 6.12-rc2, 6.12-rc3, 6.12-rc4, 6.12-rc5 — fixed in 6.11.7, 6.6.60
