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.
