CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in Linux Kernel up to 7.1.9 and classified as problematic. This vulnerability affects the function rmi_f54_buffer_queue of the component synaptics-rmi4. The manipulation with an unknown input leads to a uninitialized pointer vulnerability. The CWE definition for the vulnerability is CWE-824. The product accesses or uses a pointer that has not been initialized. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - propagate F54 worker errors to V4L2 queue Previously, rmi_f54_buffer_queue() waited for the worker thread to finish but ignored whether it succeeded. If the worker failed (e.g., due to a timeout or register read failure), the queue thread would silently return success, delivering stale or uninitialized memory to userspace. Add a 'report_error' field to struct f54_data to store the worker's exit status. Check this field in rmi_f54_buffer_queue() after the worker finishes, and mark the buffer as VB2_BUF_STATE_ERROR if an error occurred.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2026-80567 since 08/26/2026. The exploitation appears to be easy. The attack needs to be approached locally. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/26/2026).
