CVE-2026-72480
iio: adc: xilinx-ams: fix out-of-bounds channel lookup in event handling
Overview
Description

In the Linux kernel, the following vulnerability has been resolved: iio: adc: xilinx-ams: fix out-of-bounds channel lookup in event handling ams_event_to_channel() may return a pointer past the end of dev->channels when no matching scan_index is found. This can lead to invalid memory access in ams_handle_event(). Add a bounds check in ams_event_to_channel() and return NULL when no channel is found. Also guard the caller to safely handle this case.

Solution
Check array bounds in channel lookup to prevent invalid memory access.
  • Add bounds check in ams_event_to_channel.
  • Return NULL if no channel is found.
  • Handle NULL return safely in caller.
