CVE-2024-43825

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”.
