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.

A flaw was found in the Linux kernel. The `synaptics-rmi4` input driver's `rmi_f54_buffer_queue()` function failed to propagate errors from its worker thread. This oversight could result in the delivery of stale or uninitialized memory to user applications, potentially leading to information disclosure or system instability.
