Overview

CVE-2026-90025 is a high-severity vulnerability. It was published on September 16, 2026 and has a CVSS 3.1 base score of 7.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

usb: typec: ucsi: displayport: Fix OOB altmode array index

The UCSI displayport driver indexes the connector's port altmode array

with the GET_CURRENT_CAM response after checking it is not 0xff. The

port altmode array is UCSI_MAX_ALTMODES elements long. If the PPM

returns an invalid GET_CURRENT_CAM response above UCSI_MAX_ALTMODES and

not equal to 0xff, the kernel may crash with an array index OOB error.

Update the UCSI displayport driver to verify the current cam is less

than UCSI_MAX_ALTMODES before accessing the port altmode array.

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.
