Overview

CVE-2026-80568 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 - block s_input when F54 queue is busy

Changing the input (diagnostic report type) mid-stream changes the

report size. Since V4L2 buffers are allocated based on the size at

stream start, changing the input while streaming could lead to a

heap buffer overflow if the new size is larger than the allocated

buffers.

Prevent this by blocking VIDIOC_S_INPUT with -EBUSY if the V4L2 queue

is busy (streaming).

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-2026-80568?

CyberStrike is an open-source, AI-augmented pentesting engine.
