Overview

CVE-2026-80754 is a high-severity vulnerability. It was published on September 3, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, 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:

Input: synaptics-rmi4 - fix F55 transmitter electrode count typo

During F55 sensor detection, the transmitter (TX) electrode count was

incorrectly assigned the value of the receiver (RX) electrode count

due to copy-paste typos.

This incorrect value was then propagated to the driver data and used

by F54 to determine the diagnostics report size. On devices with more

RX than TX electrodes, this inflated the perceived TX count, leading

to incorrect report size calculations and potential out-of-bounds

buffer accesses.

Fix the typos by correctly assigning the TX electrode counts.

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.

How can CyberStrike help with CVE-2026-80754?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-80754 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
