CVE-2026-80567
Published Aug 26, 2026
Description
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.

Frequently Asked Questions
What is CVE-2026-80567? +
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.
How do I check if I'm vulnerable to CVE-2026-80567? +
