CVE-2024-43825 high CVSS 7.8

Out-of-Bounds Write in Linux kernel (CVE-2024-43825)

Summary

Out-of-bounds write in Linux kernel (CVE-2024-43825). Successful exploitation can lead to full system takeover. Exploitable via new.

Original description

The description as published by the source.

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".
