Overview

CVE-2025-38680 is a high-severity vulnerability. It was published on September 4, 2025 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

media: uvcvideo: Fix 1-byte out-of-bounds read in uvc_parse_format()

The buffer length check before calling uvc_parse_format() only ensured

that the buffer has at least 3 bytes (buflen > 2), buf the function

accesses buffer[3], requiring at least 4 bytes.

This can lead to an out-of-bounds read if the buffer has exactly 3 bytes.

Fix it by checking that the buffer has at least 4 bytes in

uvc_parse_format().

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.
