Description

iio: Fix the sorting functionality in iio_gts_build_avail_time_table

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

iio: Fix the sorting functionality in iio_gts_build_avail_time_table

The sorting in iio_gts_build_avail_time_table is not working as intended.

It could result in an out-of-bounds access when the time is zero.

Here are more details:

1. When the gts->itime_table[i].time_us is zero, e.g., the time

sequence is 3, 0, 1, the inner for-loop will not terminate and do

out-of-bound writes. This is because once times[j] > new, the value

new will be added in the current position and the times[j] will be

moved to j+1 position, which makes the if-condition always hold.

Meanwhile, idx will be added one, making the loop keep running without

termination and out-of-bound write.

2. If none of the gts->itime_table[i].time_us is zero, the elements

will just be copied without being sorted as described in the comment

"Sort times from all tables to one and remove duplicates".
