Overview

CVE-2026-80570 is a high-severity vulnerability. It was published on August 26, 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 - zero report size on F54 work error

In rmi_f54_work(), if an error occurs during report request or command

verification, the code jumped directly to the 'error' label, bypassing

the 'abort' label where f54->report_size was normally zeroed out.

This left f54->report_size containing its previous successful payload

size. If a user then altered the V4L2 format to a smaller size, and a

subsequent run failed, rmi_f54_buffer_queue() would copy the stale,

larger payload size into the shrunken V4L2 buffer, causing a heap

buffer overflow.

Fix this by merging the 'abort' and 'error' labels into a single 'out'

exit path, and ensuring that f54->report_size is always set to 0 on

failure by checking for error and zeroing the local report_size first.

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-2026-80570?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-80570 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.
