Overview

CVE-2025-38484 is a high-severity vulnerability. It was published on July 28, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

Technical description

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

iio: backend: fix out-of-bound write

The buffer is set to 80 character. If a caller write more characters,

count is truncated to the max available space in "simple_write_to_buffer".

But afterwards a string terminator is written to the buffer at offset count

without boundary check. The zero termination is written OUT-OF-BOUND.

Add a check that the given buffer is smaller then the buffer to prevent.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
